    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.

    LS MnM targets battery-materials growth with smelter-derived sulphuric acid

    South Korean metals producer LS MnM plans to use sulphuric acid recovered from copper-smelting operations to process nickel and cobalt for battery materials, linking its existing metals business with its expansion into the electric-vehicle supply chain. The company captures sulphur dioxide generated at its Onsan Smelter and converts it into sulphuric acid. LS MnM’s sulphuric-acid facilities have annual capacity of 1.925 million t/a, according to the company, providing a potential internal reagent source for hydrometallurgical processing.

    MoU on coal gasification

    Coal India Limited (CIL) says that it has executed a non-binding memorandum of understanding (MoU) with ArcelorMittal Nippon Steel India Private Limited (AMNS), to examine the use of syngas from a gasification facility which CIL would set up next to the ArcelorMittal’s Paradip pellet plant in Odisha state. The company says that it will be “exploring the possibility of utilising syngas produced from a coal gasification facility… coupled with CCUS.” The focus of the MoU will initially be to assess the technical, commercial, and implementation aspects of the project and to facilitate preparation of a preliminary feasibility report for evaluating project viability.
