Precious metals can be found in ore deposits along with sulfur, and are known as sulfid Cadmium, cobalt, copper, lead, molybdenum, nickel, silver, zinc, and gold and platinum group metals can be found in sulfide forms These concentrated ore deposits are considered low grade because of the economic costs associated ....
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 01mm, giving the ore a texture similar to table salt...
As the mixture of metals is allowed to cool, a crust of zinc and silver forms on the surface The crust is removed, and the metals undergo a distillation process to remove the zinc from the silver To extract silver from copper-containing ores, an electrolytic refining process is used...
