COPPER Copper production - TU Delft

About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate

Nickel processing - Extraction and refining | Britannica

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 higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...

Talk:Copper extraction - Wikipedia

This article is a little unwieldy and far-reaching to my mind. Copper extraction obviously involves a lot of things related to many wide and varied subjects, a lot of which actually have nothing to do with the extraction per se, of copper. This, sadly includes; All of the geology and formation of copper orebodies

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 ...
