Mixed smelter for Tennessee

Korea Zinc says it will partner with the US government to construct a critical minerals smelter in Clarksville, Tennessee, producing zinc, lead, and copper. Korea Zinc will begin site preparation next year, followed by phased commercial operations from 2029. The plant is planned to process around 1.0 million t/a of raw materials and turn out 540,000 st/a of finished products. Processing of gold, silver, and key strategic minerals such as antimony, indium, bismuth, tellurium, cadmium, palladium, gallium and germanium, are also planned in what is being touted as a "state-of-the-art" facility. Sulphuric acid and semiconductor-grade sulphuric acid will also be produced. The output will include 300,000 t/a of zinc production, 200,000 t/a of lead, 35,000 t/a of copper and 5,100 t/a of rare and strategic metals. Development will be through Korea Zinc’s US subsidiary, Crucible Metals.

Capacity increase at Heartland Sulphur

Heartland Sulphur says that it has debottlenecked its crushed bulk sulphur remelting operations, increasing capacity by 40%. Heartland says that the increase boosts the company’s sulphur handling efficiency and service capability for producers and buyers. It has also completed a full feasibility study and retained engineering partners to add an additional 1,000 t/d of sulphur remelt capacity, slated to be fully operational by yearend 2026. Heartland Sulphur can form 4,500 t/d for offshore markets, transport molten sulphur by tank car to destinations across North America, and accept and condition sulphur in both molten and solid states. The company’s existing remelt capacity stands at 700 t/d and is projected to reach a total of 1,700 t/d (560,000 t/a) by the end of 2026.

Sulphur ban extended

At the end of December, the Russian government extended its ban on the export of technical sulphur until at least the end of March 2026. The move prolongs the initial restrictions, which were first reported on 4 November and which were set to expire at the end of 2025. The initial ban was widely expected and followed early September drone strikes on the Astrakhan and Orenburg natural-gas plants. The official justification for the extension remains to “stabilise shipments of raw materials to the domestic market” and maintain production volumes for mineral fertilizers, according to the government’s press service Interfax.

Arianne to receive government support

Arianne Phosphate says that the government of Canada has approved contribution funding of up to C$735,000 to support the company’s ongoing work on processing phosphate rock and optimising its purified phosphoric acid (PPA) process. The funding, provided through Natural Resources Canada’s Critical Minerals Research, Development and Demonstration programme, is part of a C$80.3 million investment announced by Prime Minister Mark Carney to help build secure critical minerals supply chains in Canada. Phosphate was added to the Canadian critical mineral list in 2024. Arianne’s Lac à Paul project is the only fully permitted phosphate mine in the country. Arianne is now actively pursuing opportunities for the downstream production of PPA, a necessary ingredient for lithium-iron-phosphate batteries.

Approval for phosphate expansion

Madhya Bharat Agro Products has announced board approval for a major capacity expansion at its Dhule manufacturing facility. The expansion represents a comprehensive enhancement of the company's fertilizer production capabilities, including 330,000 t/a of diammonium phosphate and NPK fertilizer, a 66,000 t/a phosphoric acid plant, and a 396,000 t/a sulphuric acid plant. The expansion plan is part of a strategy of vertical integration in fertilizer production. The addition of phosphoric acid and sulphuric acid production capabilities will support the primary DAP/NPK manufacturing operations, creating operational synergies and potentially reducing input costs, according to the company.

Indonesian nickel shutdown signals risk for sulphur demand

PT QMB New Energy Materials, a major Chinese-owned nickel smelter in Indonesia, is temporarily cutting production due to mounting waste management challenges, according to a 24 November report from local news source Sina, a move expected to temporarily impact regional sulphur demand. The facility, located in the Morowali Industrial Park, will reduce output for at least two weeks as its tailings ponds are nearing capacity while it awaits approval for a new facility. The shutdown may have implications for the sulphur market, as QMB is a major consumer.

Manyar smelter faces supply issues

Freeport Indonesia may be forced to suspend operations at its Manyar smelter at the end of October due to a lack of copper concentrate, according to local press reports. The news follows the mudslide at the Grasberg mine in September, which killed seven workers. Grasberg, which represents almost 3% of global copper mine production, has halted production and Freeport says that it may not return to pre-accident operating rates until 2027. Stocks of copper concentrate at Grasberg were estimated to be only sufficient to operate the Manyar smelter until the end of October. The $3.7 billion Manyar smelter only resumed operations in May after a fire broke out in October last year, damaging the plant.

Sultech to supply micronised sulphur technology

Sultech Global Innovation Corp., a Canadian agricultural technology company, has signed a memorandum of understanding (MoU) with ADNOC Sour Gas for its micronised elemental sulphur technology. Under the MoU, the companies will conduct a feasibility study and pilot production program to establish the UAE’s first commercial micronised sulphur manufacturing facility. The initiative will integrate Sultech’s patented micronisation process within ADNOC’s sulphur granulation at the Shah Gas Plant, the world’s largest ultra-sour gas operation.
