CA2598055C - Method for the recovery of gold from sulphide ...

The invention relates to a method for recovering gold from a sulphidic concentrate, particularly one containing arsenopyrite and/or pyrite, hydro-metallurgically. The concentrate is first subjected to leaching with a concentrated solution of alkali chloride and copper (II) chloride, by means of which the copper minerals and some of the gold in the concentrate are made to dissolve.

The ore is then ground finely before the copper-bearing sulphide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate can contain between 25 and 57% copper.

The gangue particles can consist of a range of silicate minerals from quartz to talc and clays. Carbonate mineral gangue can also be present. When liberated, typical copper sulphide minerals are relatively easy to float. When there are no overriding metallurgical issues, producing a sufficiently high copper concentrate grade is often the focus.

Extraction Of Copper - Chemistry

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

COPPER Copper production - TU Delft

Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 % Cu) must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue.
