Copper Mining and Processing: Processing Copper Ores
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and …

How silver is made
Silver was first obtained in sixteenth-century Mexico by a method called the patio process. It involved mixing silver ore, salt, copper sulphide, and water. The resultant silver chloride was then picked up by adding mercury. This inefficient method was superseded by the von Patera process. In this process, ore was heated with rock salt ...

PARTING: Separate Gold and Silver by Melting
The processes of parting may be tabulated as follows: Cementation. Melting with sulphide of antimony. Melting with sulphur, and precipitation of the gold from the regulus by silver, iron, or litharge. Parting by nitric acid. Parting by sulphuric acid, sometimes called "refining.". A combination of these last two methods.
