Extraction Of Copper Mining Concentration Smelting

The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

Copper Mining amp Extraction Process Flow Chart

Aug 26, 2015 The copper oxide minimum minerals are dissolved by the acid to give a blue copper rich solution mainly of copper sulfate. This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper.

Innovations Introduction to Copper Mining amp Extraction

There is no shortage of copper resources. In fact, copper is one of the most abundant of the metallic elements in the earth's crust. The average estimated concentration is between 55 and 70 mg/kg, placing it below chromium (200 mg/kg) and zinc (132) but above tin and lead. Commercially exploited deposits of copper ores are found in many parts ...

Gold processing Mining and concentrating Britannica

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Concentration of Ores Hydraulic Washing Froth Flotation

Learn the process of extracting Crude Metal from Concentrated Ore. Froth Flotation Process. Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals.
