An innovative copper-processing solution developed by AMMAN in Sumbawa, utilizing Controlled Potential Sulfidisation (CPS) technology combined with Oxidation Reduction Potential (ORP) sensors, has received international recognition. Didit and his colleagues from the Metallurgy team at the Batu Hijau processing plant have continuously sought innovative ways to enhance value creation in mining operations. Their drive for improvement stems from the positive workplace culture fostered by PT Amman Mineral Nusa Tenggara (AMMAN), one of Indonesia’s largest copper and gold mining companies.Drawing on their technical expertise, the team focused on improving copper recovery rates. Higher recovery means a greater proportion of copper contained in mineral ore can be converted into concentrate products, while reducing the amount lost to tailings.The ore processed at Batu Hijau may come either directly from mining operations or from stockpiles—ore that has been previously mined and stored for future production requirements. Processing stockpiled ore presents a particular challenge because prolonged exposure to the environment causes oxidation, which can reduce copper recovery rates when the material is processed through the flotation plant. If left unaddressed, declining recovery levels can gradually erode the economic value of stockpiled ore over time.Driven by a commitment to continuous improvement, Didit and his colleagues developed an innovative solution to address this issue through the implementation of Controlled Potential Sulfidisation (CPS) enhanced by Oxidation Reduction Potential (ORP) sensor technology.The innovation significantly increased copper recovery rates. Notably, the improved performance was achieved while reducing chemical consumption by as much as 18.3 percent. The result represents a tangible example of more efficient and productive operations, where technology optimizes resource utilization while lowering operating costs.Precision and Consistency Behind CPS TechnologyControlled Potential Sulfidisation (CPS) is a process designed to enhance the flotation performance of copper-bearing minerals, enabling them to be separated and recovered more effectively. The AMMAN Metallurgy team integrated Oxidation Reduction Potential (ORP) sensor technology to monitor the chemical condition of processing slurry in real time. The system provides more accurate operational data, allowing metallurgists to precisely control the dosage of sodium hydrosulfide (NaHS), the activating reagent added to the slurry.Much like seasoning in cooking, the reagent must be added in the correct amount. With precise dosing, copper minerals that were previously difficult to recover become more readily recoverable during flotation. Flotation is the process by which copper- or gold-bearing minerals attach to air bubbles and rise to the surface, allowing them to be separated from waste material.International RecognitionThe success of the innovation was documented in a technical paper presented in Adelaide, Australia, at one of the mineral processing industry's most prestigious metallurgical conferences, where global experts gather to exchange knowledge and best practices in mineral plant design and operations.Representing AMMAN, Didit and his colleagues received significant recognition when their paper was awarded the conference’s “Best Paper” honor. The achievement demonstrates that innovation originating from Sumbawa and developed by local Indonesian talent is capable of competing and being recognized at the international level.As a native of West Sumbawa, Didit said the innovation was made possible by an environment that actively encourages improvement and creativity. “At AMMAN, we are constantly encouraged to keep improving and never become complacent. A highly supportive work culture, strong teamwork, and leadership support were all key factors behind this innovation. The company provides broad opportunities for us to continue innovating and developing the most effective systems. For me, this is proof that local talent from West Sumbawa can produce technical achievements that earn global recognition,” Didit said.

Aneka Tambang (ANTM) to Channel Ferro Alloy Exports Through Single-Window DSI System
Aneka Tambang (ANTM) to Channel Ferro Alloy Exports Through Single-Window DSI System
02 Jun 2026, 04:25 PM 414

PT Aneka Tambang Tbk (ANTM) has expressed its readiness to support the government’s single-gate export policy under the supervision of PT Danantara Sumberdaya Indonesia (DSI). Ferroalloys—one of three strategic natural resource commodities designated for export monitoring through DSI—are among the products affected by the new mechanism.Antam Corporate Secretary Wisnu Danandi Haryanto said the company produces ferroalloys in the form of ferronickel (FeNi). The product is manufactured at Antam’s nickel processing and refining facilities (smelters) operated by its Nickel Mining Business Unit (UBPN) in Kolaka and Pomalaa, Southeast Sulawesi.For 2026, Antam has set a ferronickel production target of approximately 18,000 tonnes of nickel contained in ferronickel (tNi). At present, the majority of the company’s ferronickel output is sold to export markets, primarily China, South Korea, and India, as well as several European countries in smaller volumes.“In principle, Antam supports the Government’s efforts to strengthen the governance of trade and exports of Indonesia’s strategic commodities, including policies aimed at improving efficiency, transparency, and the competitiveness of the country’s exports. Fundamentally, Antam has no objection to the policy,” Wisnu told Kontan.co.id on Tuesday (June 2, 2026).Wisnu noted that Antam’s ferronickel exports have so far been conducted in accordance with all applicable laws and regulations, including licensing requirements and export governance provisions established by the Government. Consequently, the company is prepared to adjust its export procedures in line with the new policy framework.He emphasized that any adjustments would be implemented while safeguarding operational continuity, maintaining strong customer relationships, and supporting national efforts to enhance value-added processing and strengthen Indonesia’s export competitiveness.Wisnu added that Antam’s business remains overwhelmingly focused on the domestic market. “Approximately 97% of Antam’s sales are directed to the domestic market, meaning the company’s export share remains relatively limited,” he said.As previously reported, the Government has begun implementing a new reporting mechanism for exports of three strategic natural resource commodities: coal, palm oil, and ferroalloys. The transition period commenced on Monday, June 1, 2026.Under the policy, exporters are required to report their export activities for these commodities to DSI. The transition phase will remain in effect until the Government conducts an evaluation after the first three months of implementation.The results of that evaluation will serve as the basis for the next stage of the program. The Government aims to fully implement the DSI-supervised export mechanism no later than January 1, 2027.

BUMA International (DOID) Records IDR 5.4 Trillion Revenue in Q1 2026
01 Jun 2026, 06:53 PM 522

PT BUMA International Group Tbk. (DOID) recorded revenue of USD 318 million, equivalent to IDR 5.4 trillion, in the first quarter of 2026 (based on the Jisdor exchange rate of IDR 16,999 per US dollar as of March 31, 2026).In its official statement, BUMA management explained that the company posted revenue of USD 318 million, down 10% year-on-year (YoY), in line with a smaller active portfolio.The Average Selling Price (ASP) of its mining contractor business increased 3% YoY, supported by a higher proportion of rise-and-fall contracts as well as tiered tariff increases linked to coal prices.Meanwhile, EBITDA surged 98% YoY to USD 28 million from USD 14 million in the first quarter of 2025, with the EBITDA margin improving to 11% from 5% in the same period last year.DOID also recorded a net loss of USD 24 million, equivalent to IDR 407.97 billion, compared to a net loss of USD 70 million in the first quarter of 2025.Management stated that the 66% YoY improvement reflected EBITDA recovery along with three supporting non-operational factors: a USD 12 million gain from the ongoing optimization of the ACG portfolio through land asset sales, a USD 12 million reduction in investment losses from 29Metals, and the absence of a USD 4 million receivables provision in Australia that had been recorded in the first quarter of 2025.BUMA International Group Director Iwan Fuad Salim said the first quarter of 2026 demonstrated that the recovery initiated throughout 2025 continued despite the seasonally challenging quarter.“EBITDA nearly doubled year-on-year despite lower revenue, supported by stronger cost discipline and improved productivity,” said Iwan.He also noted that operational discipline and EBITDA improvements remained intact through the peak rainy season in February, providing DOID with a stronger foundation for the rest of the year.“The foundation has been established, and our focus going forward is solid execution as we enter the drier operational quarters,” he added.DOID also recorded capital expenditure of USD 20 million, allocated to maintaining fleet reliability and operational sustainability.Meanwhile, free cash flow turned positive at USD 2 million, compared to negative USD 19 million in the first quarter of 2025. The improvement was mainly driven by USD 17 million in proceeds from land sales under the ACG portfolio optimization framework, supported by EBITDA recovery and significantly lower capital expenditure.Operationally, overburden removal volume declined 12% YoY to 89 million bank cubic meters (MBCM), while coal production fell 20% YoY to 15 million tons (MT).The decline in volumes primarily reflected the completion of contracts at the Binungan site in Indonesia and the Burton site in Australia, as well as ramp-down activities at two Indonesian sites during 2025.

Coal Prices Surge Close to USD 140, China and India Scramble for Supply
Coal Prices Surge Close to USD 140, China and India Scramble for Supply
27 May 2026, 06:39 PM 670

Coal prices surged amid market concerns over supply conditions in China and strong demand from India.According to Refinitiv data, coal prices closed at USD 139.4 per ton on Tuesday (May 26, 2026), rising 2.16%. The latest closing price marked the highest level since May 5, 2026, or in more than three weeks.Coke prices in China officially increased for the fourth time this year after major steel mills accepted price hikes proposed by coke producers. The latest increase took effect on May 26, amounting to around CNY 50–55 per ton.The increase came amid tightening coking coal supply following a mining accident in Shanxi, China’s key coal-producing region.Large-scale safety inspections forced several mines to temporarily halt production, raising market concerns that supply could shrink further.After the fourth round of price hikes took effect, the market immediately began discussing the possibility of a fifth increase.Coal Price Performance (USD/tonSource: RefinitivIndustry players believe coke producers now hold stronger bargaining power as market inventories remain relatively low while demand from the steel industry stays fairly stable.However, not all parties agree. Several steel mills have begun resisting further price increases as profit margins in the steel sector remain under pressure due to weakening steel prices. Tensions between coke producers and steelmakers have started to emerge.Meanwhile, the global coking coal market has also strengthened. Australian and Chinese coking coal prices climbed throughout May due to tight supply conditions and production disruptions in several mining regions.Following a mining accident that killed 82 people last week, authorities in Shanxi suspended operations at 109 mines with a combined annual production capacity of 122 million tons.The fatal explosion occurred at the privately owned Liushenyu mine on Friday night.Most mines are typically required to suspend operations for three to seven days after a serious incident.The market is now watching closely to see whether the scope of the shutdowns will be expanded, especially as China prepares to launch its annual mining safety campaign on June 1.If Beijing does not impose broader restrictions, coal production could recover quickly once the initial inspections are completed, potentially putting downward pressure on prices again.“Considering the need to maintain coal supply ahead of summer, the central government has so far not tightened safety supervision further,” said Yu Dian, lead researcher at Shanghai-based Citic Futures, as quoted by The Star.The explosion killed at least 82 people and suddenly tightened China’s coking coal market, directly impacting around 4% of total national production. Mysteel reported that several mining companies had already started receiving higher price offers following the disaster.Coking coal futures rose 0.5% to 1,273 yuan per ton at 11:01 a.m. Singapore time. Meanwhile, iron ore prices on the Singapore Exchange fell 1.4% to USD 105.20 per ton. Iron ore prices in Dalian and steel prices in Shanghai also weakened.Summer Demand Drives ConsumptionIn addition to the inspections, summer is approaching and electricity demand is entering its peak period. Institutions such as CITIC Securities noted that this year’s summer demand — including coal consumption by coal-fired power plants and the chemical sector — has exceeded expectations.Downstream users are currently reducing inventories during the low-demand season, but restocking demand for the peak season could emerge at any time.On one side, coal supply is shrinking, while on the other, demand remains stable or is even increasing. Naturally, the remaining coal supply has become increasingly contested.As a result, coal prices were immediately repriced in the futures market.Front-month coking coal futures surged nearly 8% in a single day, while contracts for the following month also hit their daily price limit.From India, state-owned miner Coal India instructed its subsidiaries to increase coal supply to power plants.The move aims to avoid shortages as the country’s electricity demand reaches record highs due to an extreme heatwave, according to two sources familiar with the matter.Several regions in India have experienced power outages, especially at night when renewable energy supply is unavailable. The situation comes after extreme temperatures triggered by El Niño weather patterns placed heavy pressure on the national power grid.A total of 21 power plants were reported to have critically low coal inventories — enough to meet demand for less than one week — based on the latest data from the Central Electricity Authority, an advisory body under India’s Ministry of Power.The world’s largest coal producer has instructed its subsidiaries to maximize coal shipments through all transportation modes, including railways transporting coal directly from mines to power plants, the sources said.Coal India on Tuesday stated that it had asked power utilities to increase coal inventories earlier ahead of peak demand, especially for plants located in areas with logistical challenges.India’s peak power demand, which measures maximum electricity requirements, reached a record high of 270.8 gigawatts (GW) last week.Although India already has 228 GW of non-fossil fuel energy capacity, coal still accounts for more than 70% of the country’s electricity generation.Coal India and its eight subsidiaries, which contribute around 80% of India’s coal production, recorded a 9.7% decline in output to 56.1 million metric tons in April, according to company data.The mining company stated that it currently holds coal inventories totaling 168 million tons, including 47.6 million tons at power plants, enough to meet consumption for 19 days.Meanwhile, coal stockpiles at mining sites reached 113.5 million tons as of May 23, up around 10% compared to the previous year.

Tsingshan Cuts Nickel Production at Weda Bay for Aluminium
Tsingshan Cuts Nickel Production at Weda Bay for Aluminium
19 May 2026, 06:51 PM 567

Tsingshan Holding Group has redirected part of the electricity supply at the Weda Bay industrial area in Indonesia from nickel smelters to aluminum operations. The move signals a shift in business priorities amid soaring global aluminum prices.Quoting MINING, the policy highlights how nickel and aluminum are becoming increasingly interconnected, particularly as both metals require massive amounts of electricity for smelting operations.Tsingshan has asked several nickel pig iron (NPI) producers in Weda Bay to reduce output in June so electricity can be redirected to support aluminum operations. The request was reportedly delivered last week to NPI operators, whose products are mainly used as raw material for stainless steel.The move signals that Tsingshan’s expansion into the aluminum business is beginning to put pressure on nickel operations within the industrial zone.Tsingshan is said to be prioritizing aluminum after rising prices for the lightweight metal significantly boosted profit margins compared to the NPI business.The power diversion will utilize electricity previously allocated to 22 NPI production lines at Weda Bay, including several owned by Tsingshan itself, to support the Juwan aluminum project — a joint venture between Tsingshan and Xinfa — which has an annual production capacity of 250,000 tons of aluminum.The Relationship Between Nickel and AluminumThe connection between nickel and aluminum in this case lies in their equally high energy requirements.Until now, electricity at the Weda Bay industrial complex had mainly supported nickel smelters. However, as aluminum prices surged and profit margins improved, electricity has started to shift toward aluminum smelters, which are seen as generating higher economic returns.Three-month aluminum prices on the London Metal Exchange (LME) jumped more than 12% after the Iran conflict disrupted shipping through the Strait of Hormuz and damaged aluminum facilities in the Gulf region, which accounts for nearly 9% of global supply. Meanwhile, profit margins in the NPI business are reportedly below 10%, making aluminum increasingly attractive.The situation reflects changing dynamics within Indonesia’s metals industry. Over the past few years, industrial zones such as Weda Bay were primarily developed to support nickel downstream processing for stainless steel and electric vehicle batteries.Now, aluminum is emerging as a new sector directly competing for energy and infrastructure resources.Pressure on electricity supply is also increasing as captive power plant development is considered to be lagging behind smelter expansion.Morgan Stanley Head of China Materials Research Rachel Zhang stated that captive power plant construction typically takes around two to two-and-a-half years, while aluminum smelters can be completed in less than a year. As a result, production capacity risks operating below optimal design levels.Weda Bay, located on Halmahera Island, currently has NPI production capacity exceeding 700,000 tons per year, according to Eramet’s investor presentation in May.Tsingshan Holding Group is one of the world’s largest stainless steel and nickel producers based in China.The company is known for aggressively building an integrated metals industry chain, ranging from mining and smelting to downstream stainless steel products and electric vehicle battery materials.In recent years, Tsingshan has become a dominant player in Indonesia’s nickel downstream sector through major investments in industrial areas such as Morowali and Weda Bay.Beyond nickel, Tsingshan is now expanding into aluminum, a metal widely used in the automotive, construction, electrical cable, and electric vehicle industries due to its lightweight and corrosion-resistant properties.This diversification reflects the company’s strategy to strengthen its position in the global metals industry while capitalizing on rising aluminum prices and growing demand for lightweight materials driven by the global energy transition.
