Copper concentrate, a crucial raw material for producing electrolytic copper, contains sulfur(S), which generates sulfur dioxide(SO2) during the refining process. When SO2 is released into the atmosphere, it can cause pollution and also have harmful effects on human health. To mitigate these risks, LS MnM collects and processes these SO2, converting it into sulfuric acid products that are used as an essential material in various industries such as fertilizer, textile, medicine, steel, metal, and food.
LS MnM utilizes surplus reaction heat generated from the copper mine oxidation reaction during the smelting process to produce steam. Since 2005, we have been selling steam to Hankuk Paper, and in 2008, we expanded to S-OIL. Currently, we supply steam for four companies, including pier operators such as Jeongil, Onsan, and Hyundai. By providing steam as a heat source to these companies, we ultimately contribute to the reduction of carbon emissions.
Slag is a significant by-product generated during the copper refining process, which LS MnM processes and sells as LSFerrosand. This material is a chemically stabilized and exhibits excellent aggregate properties, making it an ideal substitute for natural aggregate. By promoting the use of LS-Ferrosand, we indirectly contribute to the conservation of natural resources. As a participant in the Molten Slags, Fluxes, Salts Conference, we actively support technology development related to slag recycling. Since the generation of slag is unavoidable as long as the smelting business is in operation, effective treatment of slag is directly linked to business continuity. We recognize slag as a resource rather than waste, and recovering valuable metals from it is an important research topic that requires extensive global research beyond LS MnM. Going forward, we will expand our network and take the lead in recovering resource from slag.
