copper gold concentrate processing

MINING TO SMELTING GOLD/COPPER CONCENTRATES IN

Copper concentrate smelting is a large scale, intensive process consisting of four stages: sulphur in the sulphide minerals is “burnt-off”; the metals are melted to form a “matte” and the waste material forms a “slag”; copper in the matte is electro-refined to copper metal; and the gold/silver is refined to doré.

Jan 01, 2016· This process is believed to be adaptable to the recovery of gold (and silver) from copper leach residues containing sulfur and may well open a new route for combined copper- and gold-processing options for copper concentrate producers. More details on this process may be found in Chapters 28 and 50 Chapter 28 Chapter 50. 2.

Whilst the smelters do charge to process our concentrate, on average for the contract terms that we have agreed with the overseas smelters, we receive 97% of the total value of gold, silver and copper.

It is not surprising to observe that the metals extraction increase when the initial cyanide concentration increases, due to higher WAD cyanide generation.

Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
