Copper Mining and Extraction: Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised

Ivanhoe to build DRC's second copper smelter amid

Ivanhoe Mines is considering construction of a new copper smelter to treat Kamoa Kakula copper concentrates following the recent push by the government of the Democratic Republic of the Congo (DRC) to facilitate local processing of copper ore.

Copper extraction by wet chemical method ScienceDirect

01/01/2018· The method involves the reduction of copper (II) ions leached from copper ore to zero valence using chlorine treated solution prepared from chicken droppings at a temperature range of 60–70 °C. The ore samples were pulverized to 250 micro millimetres and leached with hydrochloric acid to obtain leachate containing copper ions. The dissolved copper was reduced to copper metal and

Processing of Nickel Laterite Ores on the Rise

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry. The Move to Nickel Laterites

Biological methods of metal extraction Higher Material

Certain bacteria. can break down low-grade ores to produce an acidic. solution. containing copper ions. The solution is called a leachate and the process is called bioleaching . Bioleaching does

Smelting Cornish Mining WHS

Copper smelting was a technical, complex process which needed a large amount of copper ore – so initially it made sense to smelt it near where it was mined. The process also used large amounts of coal, both for fuel and as part of the reduction process. Copper was smelted in several locations around Cornwall, but principally by the Cornwall Copper Company at Hayle (1758-1819). However, later
