1 天前 The ore has first to be separated from clays and other silicates ('gangue') after which the lead ore and the zinc ore are separated. The process used is froth flotation, a succession of stages each delivering a greater concentration of the lead ore. The ore, containing gangue (which typically contains 3-8% lead) is ground with water to a ...
Lead and Zinc - Energy
2013年11月8日 6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
