Mining should continue for 11 years. ORE PROCESSING. The present lead mine concentrator was built in 1966 with rod and ball milling, lead-silver flotation, zinc flotation and low-grade middlings recovery circuits. In 1982, MIM added heavy-medium separation to pre-concentrate the mill feed. Later enhancements have included column cell flotation.

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

The most common method for accomplishing this concentration is to isolate the sulfide mineral from the impure constituents, or gangue, by flotation separation. In this process, the ore initially is crushed to about 1.9 centimetres (0.75 inch), combined with water, and ground to less than 0.1 millimetre in a ball mill.
