GIFS The 5 Stages of the Mining Life Cycle Operations

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
