Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has these operations some of the copper is oxidized to cuprous oxide and dissolved by the metal bath.

1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process.. Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).
The method of sulfide mining is broken down into five steps: : • Exploration • Development • Mining • Smelting and • Refining and reclamation. Exploration has mostly of testing the site to find if the source of the minerals is more enough to make mining the site valuable. Extensive core drilling and metallurgical mass sampling are the ...
Aug 18, 2015· The final step in production is smelting. This process involves melting the concentrate in a furnance to extract the metal from its ore. The ore is then poured into moulds, producing bars of bullion, which are then ready for sale. Closure and reclamation. The fifth and final stage in mining operations is closure and reclamation.
Copper Mining and Processing: Processing of Copper Ores. ... At the smelter, high temperatures are used to further purify the ore in a series of smelting steps. The copper concentrate is first sent through the smelting furnace to be heated up to 2,300 °F and converted into molten liquid. The heated liquid is poured into a slagsettling furnace.
steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Process Description24 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.
