In mining process, lime materials are mainly applied to refine and improve metal elements and non-ferrous metals such as Copper, Zinc, Nickel, Gold, Silver and Aluminum. Lime products are used in the froth flotation process of metals including (Copper, Nickel and Zinc as well as Gold and Silver) to ensure proper pH is maintained in the leaching circuit. Lime product is also used in precipitating impurities and regenerating caustic within the Aluminum processing.

Moreover, in the mining industry, lime products may be applied for scrubbing acid gases from smelting operations, this is to dry and stabilize waste sludge, and also as a reagent in process water treatment plants.
