Start-up for Adani smelter

Start-up for Adani smelter

Adani Group subsidiary Kutch Copper has commenced operations at its new Mundra copper refinery and smelter, the company announced on 28 March. The company previously indicated an expected start-up by the end of Q1. The new smelter will help boost domestic supplies of copper, demand for which is robust from the construction, transport and power sectors in particular and likely to double by 2030, with the shift towards clean energy and electric vehicles. This first phase of the project will have around 500,000 t/a copper capacity, with a similar capacity planned to be added in the second phase by 2029.

The first phase of the plant is expected to have 1.5 million t/a of sulphuric acid production capacity, while the phosphate-based demand for acid should be around 750,000 t/a once running. Acid exports from India are therefore expected to climb following ramp-up. The company also plans to add phosphoric acid capacity of around 500,000 t/a at the site, though this is not expected to come online until 2026.

India’s imports of copper and sulphuric acid have surged since 2018 when Tamil Nadu’s state government closed Vedanta Limited’s Tuticorin smelter on environmental grounds. Last month, the country’s supreme court rejected Vedanta’s appeal to restart the plant.

Coromandel starts trial operations at new acid plants

Coromandel International says that it has started trial production at its new sulphuric acid and phosphoric acid plants in Kakinada, Andhra Pradesh. The company says that this marks a crucial step towards transforming the unit into a fully integrated facility, significantly enhancing production capacity and diminishing reliance on imported raw materials for fertiliser manufacturing. The company is now focusing on a phased ramp-up. The new plants have of 2,000 t/d of sulphuric acid and 650 t/d of phosphoric acid, respectively. The integration of these acid plants is strategic, aligning with Coromandel's objective to strengthen backward integration in its fertiliser manufacturing value chain. By producing key intermediates in-house, the company aims to secure stable supplies, enhance cost efficiencies, and achieve greater self-sufficiency, thereby reducing dependence on imported raw materials. The project aims to replace over 50% of the Kakinada plant's imported acid requirements and mirror the integration levels seen at its Vizag and Ennore facilities.

Indonesian nickel shutdown to cut sulphur/acid demand

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.

NCOC seeks arbitration over sulphur fine

The North Caspian Operating Company (NCOC), which operates the huge Kashagan oil field in Kazakhstan, has said that it is seeking international arbitration to resolve its ongoing dispute with the government of Kazakhstan. Kazakhstan has imposed a swingeing $4.6 billion fine for alleged violations of sulphur storage regulations at the NCOC site. In December, a special administrative court in Astana turned down an appeal by NCOC, although it also granted leave to appeal in a higher court. NCOC, a partnership between Shell, Eni, TotalEnergies, ExxonMobil, China National Petroleum Corporation, Inpex and Kazakh state oil and gas company KazMunayGaz, continues to maintain that its sulphur handling operations have been conducted in compliance with Kazakhstan’s laws and that it had the required permits in place.
