Extracting Lead Materials from Ore
Usually, lead is 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 multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt.
