Workshop on beneficiation of lead zinc ore

Workshop on beneficiation of lead zinc ore

6.1.2 Lead and Zinc Ore beneficiation Due to low zinc content, run-of-mine zinc-bearing ores must be concentrated before smelting and refining. Beneficiation, which usually occurs at the mine, consists of crushing, grinding, and flotation to produce concentrates of
