processing of zinc from ore

Zinc Ore - an overview | ScienceDirect Topics1 Processing. Zinc oxide is prepared commercially by two methods: the American (or direct) process, which uses zinc ore and concentrate, and the French (or indirect) process, which uses zinc metal. Some 54% of US zinc oxide production is from zinc ore and concentrate (American process), 33% from slab zinc (French process) and 13% from secondary ...zinc ore processing from ore to metal - ME Mining MachineryZinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products..
