Lead Mining Concentration Process Flotation Filtering

Lead is extracted from ores dug from under-ground mines. Lead is also found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by- product of these other more valuable metals. Extracting the lead materials from the ore is a tedious process. First the lead ore is ground into small salt-like particles.
