网页2015年7月1日The copper extraction and metal formation is a “one-pot” process using a molten eutectic mixture of NaCl, KCl and ZnCl 2 as both the lixiviant (to dissolve copper and copper oxide from copper concentrate ore or slag) and as an ionically conductive electrolyte medium for electrodeposition of copper ions as copper metal.

Extraction of Copper Oxide (I): Purified CuSO4 Solution
网页2023年3月16日The deductions reached are that extraction of copper from waste copper dust (WCD) takes place rapidly and plateaus after approximately 30 minutes. This trend was observed across the different concentrations. The presence of Fe 2+ in the leach solutions has the capacity to lower the Eh, thus causing the plateau in copper extraction.

An investigation into the leaching behaviour of copper
网页2017年1月1日Copper oxide minerals are normally extracted by acidic leaching followed by copper recovery with solvent extraction and electrowinning. However, copper oxide deposits often containing large amounts of acid consumable gangue leads to a very high acid consumption.

网页The extraction of copper also involves many steps. The ore used for extraction is copper pyrites, For example, if you react copper(I) oxide with hot dilute sulfuric acid, you might expect to get a solution of copper(I) sulfate and water produced. In fact you get a brown precipitate of copper and a blue solution of copper(II)
