Aug 28 2014 This refining process removes any remaining nonlead materials e.g. gold silver bismuth zinc and metal oxides such as oxides of antimony arsenic tin and copper. While the gold and silver are considered to be pollutants in the refinement process these elements can be more profitable than the primary ore elements.

Zinc processing - Zinc processing - Ores Zinc ores are widely distributed throughout the world although more than 40 percent of the worlds output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite ZnS a ferrous form of zinc blende known as marmatite ZnFeS and a zinc carbonate known as calamine

Dec 18 2016 When silver is a byproduct of processing these other minerals then a different method has to be used to extract the silver ore. For example is silver is found in ore containing zinc a method known as the Parkes Process is used to mine the minerals. When using this method the ore is first heated until it melts. When the ore is the cooled down a .

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.
Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores the Parkes process is used. In this method the ore is heated until it becomes molten. As the mixture of metals is allowed to cool a crust of zinc and silver forms on the surface.
