Limestone is used in various metal production applications for example steel making, copper production and metal recycling. Lime can be delivered as limestone, quicklime or slaked lime, depending on application.
Unit operations in metal production are blast furnace, electrical arc furnace, steel converter process and ladle metallurgy. The purpose of lime, as quicklime, is to form a high basicity slag, in order to remove impurities from the melt into the slag phase. Impurities can be, for example, sulphur, phosphorous and other unwanted elements.
Lime is also utilized for protecting the environment with effluent treatment, such as process water treatment and flue gas treatment.
Nordkalk can supply different lime qualities to fit the need for the specific applications. Lime can be delivered in bulk, discharged into a silo. Alternatively, packed in small or big bags.
Selecting the most suitable lime product ensures easy process control, which helps to match the target quality – and maintain low processing costs.
