Copper Mining and Processing Processing of 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.

Mineral Concentrate Marketing Treatment Charges amp; Penalties

If the ore treated will not produce a fluid slag, fluxes such as silica, iron or lime must be added and a penalty charge made for such added expense. High grade concentrates from jigs, concentrating tables, or other recovery methods and those containing metallics as native gold or silver should be sold separately from lower grade products for best returns.

What is the typical concentration for silica or silicates

Silica (SiO2) is an oxide of silicon, and is present in almost all minerals It is found in surface and well water in the range of 1 100 mg/i. Silica is considered to be colloidal in nature because of the way it reacts with adsorbents. A colloid is a gelatinous substance made up of non173;diffusible particles that remain suspended in a fluid medium.
