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 pyrometallurgy, respectively, due to the different ...

B. Placer Mining Claims: are located upon deposits of loose, unconsolidated material, such as gravel beds, or upon certain consolidated sedimentary deposits lying at the surface. There are few limitations on the exterior dimensions of a placer mining claim, but a single individual cannot locate more then 20 acres in each claim.

1.1.3.2 Placer mining Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called 'hydraulic mining') are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer
