copper and cobalt ore processing

cobalt processing | Uses, Supply, & Facts | Britannica

From copper and nickel processing. Cobalt contained in and smelted with copper concentrate is oxidized along with iron during the final conversion to blister copper. It then enters the slag layer, which can be treated separately, usually in an electric furnace, and the cobalt recovered by reduction with carbon to a copper-iron-cobalt alloy. In

Cobalt processing The metal and its alloys | Britannica

Cobalt processing Cobalt processing The metal and its alloys: In the production of a so-called cemented carbide, such as tungsten carbide, a briquetted mixture of tungsten carbide and cobalt powder is heated at a temperature above the melting point of cobalt. The latter melts and binds the hard carbides, giving them the toughness and shock resistance needed to make carbides of practical

Sep 06, 2019· The ore is mixed with calcium oxide and silica, producing a slag. This makes it possible to separate silver, a mixture of materials rich in copper, nickel and cobalt and a scorifiable residue. This mixture rich in copper, nickel and cobalt is what is technically called “speiss”. Getting from this mixture to the pure metal is a complex process.

Segregation Process of Mixed Sulphide Copper Ore

Thus copper values, originally disseminated in ore particles “segregate” to the surface of coke particles. The segregated ore is then wet ground in a ball mill and floated in a conventional way. The segregation process does not affect sulphide copper minerals and they float together with the segregated charge in a common concentrate.

How Hydrometallurgy and the SX/EW Process Made Copper the

In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.
