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.
