Copper Concentration Operation

Copper concentration is the process of obtaining copper from its ores. This operation consists of a series of chemical, physical, and electrochemical processes. As in all mining operations, the ore must usually be beneficiated or concentrated. To do this, the ore is first crushed and grinded, then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. Finally, it undergoes various refining processes, the final one being electrolysis.

Copper Crushing Plant

Copper crushing may be performed in two or three stages. Primary crushing systems consist of crushers, feeders, dust control systems, and conveyors used to transport ore to coarse ore storage. Primary crushing is often accomplished by a jaw or gyratory crusher, since these units can handle larger rocks. According to production requirements, secondary and tertiary crushing will be applied, the crushing plant involved includes impact crusher and cone crusher.

Copper Grinding Mill

Grinding is the last stage in comminution. In this operation, ore particles are reduced and classified (typically in a hydrocyclone) into a uniformly sorted material between 20 and 200 mesh. Most copper facilities use a combination of rod and ball mills to grind sulfide ore. Rod mills use free steel rods in the rotating drum to grind the ore. Othe types of grinding mill used in copper concentration includes high pressure mill, vertical roller mill, ultrafine mill, trapezium mill etc.

Copper Flotation Machine

The purpose of concentration is to separate the valuable mineral (or “values”) from nonvaluable minerals (referred to as “gangue”). There are a variety of concentration methods. Froth flotation is the standard method of concentration used in the copper industry.

The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals. The ore is then wet, suspended in a slurry, and mixed with xanthates or other reagents, which render the sulfide particles hydrophobic. Typical reagents include potassium ethylxanthate and sodium ethylxanthate, but dithiophosphates and dithiocarbamates are also used.
