Four Chinese-operated nickel plants at the Indonesian Morowali Industrial Park have temporarily ceased operations following a fatal landslide in February, in a development that will significantly reduce regional demand for sulphur and sulphuric acid. The shutdowns affect facilities run by China’s GEM Co. and its partners, which together account for 30% of Indonesia’s high-pressure acid leaching (HPAL) capacity. The move comes amid heightened regulatory scrutiny. The largest of the four plants, PT QMB New Energy Materials, could remain offline for up to three months.

Taseko Mines’ Florence Copper project, featuring Metso’s copper solvent extraction and electrowinning (SX-EW) technology, is ramping up its commercial operations in Arizona. The successful harvesting of the first copper cathodes at the end of February 2026 is an important milestone for Taseko Mines and Metso, marking the first new greenfield copper production in the United States since 2008. The project caters to the rapidly growing copper demand while supporting the transition towards more environmentally responsible copper production in North America.

• Market sentiment has shifted decisively from bearish to bullish as the conflict in the Middle East has triggers a significant price rally.

Conflict in the Middle East has halted all vessel traffic through the Strait of Hormuz, effectively paralysing a region that accounts for 48% of global seaborne sulphur trade. As a result, the sulphur spot market has ground to a halt, with prices notionally holding unchanged in the $490-515/t f.o.b. range simply due to a lack of activity. No spot offers were reported out of the Middle East.

Worley Comprimo has carried out an evaluation of technologies allowing 99.8+% sulphur recovery for an Indian refinery case. The TopClaus process was compared to alternative technologies, focussing on modern technical challenges, investment operation and maintenance costs, as well as CO2 considerations.

The Saudi Arabian Mining Company (Ma’aden) says that the Ministry of Energy has approved the allocation of feedstock for its fourth phosphate project. This project aims to produce approximately 1.1 million t/a of ammonia and increase the production of phosphate and specialty fertilizers by about 2.5 million t/a, raising the company’s total production capacity to nearly 12 million t/a. This will further solidify Ma’aden’s position as one of the world’s largest producers of phosphate fertilizers, according to a company statement. Ma’aden will now commence engineering studies and obtain the necessary approvals.

Metso says it has won a €180 million order for the delivery of engineering and key process equipment for a new primary copper smelter investment at an undisclosed location in Asia. The planned production capacity of the copper smelter complex is 300,000 t/a of copper cathodes and 1.1 million t/a of sulphuric acid, based on licensed Outotec® Flash Smelting, PS Converting and Lurec® technologies. It includes the design and supply of key process equipment for the main areas of the smelter complex, and the gas cleaning and sulphuric acid plant, copper electrolytic refinery, and precious metals refinery. The delivery also comprises site services and spares.
