Hydrometallurgical separation of zinc and copper from ...
2020-3-1 The separation of zinc and copper from brass ash residues was evaluated using a hydrometallurgical route comprised of two main steps: (i) selective leaching of zinc with dilute sulfuric acid and (ii) selective solvent extraction of zinc with D2EHPA. The route produced an aqueous solution rich in zinc and a leaching residue rich in copper.

copper extraction and purification - chemguide
2015-7-26 Purification of copper. When copper is made from sulphide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper - hence "blister copper") and then cast into anodes for refining using electrolysis. Electrolytic refining

Blister Copper - an overview ScienceDirect Topics
Copper production begins with ore milling and copper separation by flotation in order to produce a concentrate with a copper content of about 30%. The produced concentrates are smelted to remove volatile and other impurities and by further purification of the copper melt from the smelter, a primary form of the metal, known as blister copper is ...

The primary production of sulfide concentrates includes smelting to copper matte or blister copper, conversion of matte to blister copper, and refining to copper. Smelting, converting, and fire-refining can use a limited amount of secondary materials. Molten copper can effectively dissolve many metals, from valuable noble metals to harmful impurities such as bismuth.

Processing method of copper anode slime
FIELD: metallurgy. SUBSTANCE: method includes antimony and lead leaching from copper anode slime in a solution containing 50-200 g/dm 3 of glycerin, 50-100 g/dm 3 of alkali and a reducing agent, in an amount that provides the system oxidation-reduction potential more positively than +0.8 V at a temperature of 70-90°C for 2-3 hours. Thus lead from the leach solution is educed by known methods.

2021-2-13 There are only a few smelters processing copper concentrates directly into blister copper. Despite the many advantages of this process, a serious challenge of this technology is the need to process the resulting flash smelting slag. It contains 12–15% copper and 2.5–4% lead. In this form, it cannot be considered as waste material and, therefore, a high-temperature reduction process is ...
