Process Description
Mining:
Lead –Zinc ore is divided into stope blocks which are drilled and blasted using long hole open stoping mining method. Ore is either crushed to underground or at surface to feed mill. A backfill and a paste fill plants were recently completed to use tailings from ore beneficiation plants. The mine also has a dry stack tailing plant, the first of its kind in India.
Processing:
The ore is further crushed and milled before undergoing a flotation process, to produce the concentrate. Zinc and lead concentrates produced are transferred to our smelters.
