Extraction of Metals of Least Reactivity and Medium …
Extraction of Copper. Copper glance (Cu 2 S) is roasted in the presence of air. This results in oxidation of copper sulphide to give copper oxide. Roasting turns copper glance (ore of copper) into copper (I) oxide. 2Cu 2 S + 3O 2 ⇨ 2Cu 2 O + 2SO 2. After that, copper oxide is then heated in the absence of air, so that it can undergo calcination.

The Extraction of Copper
Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest …
Extraction of copper by smelting uses silica as an additive …
The extraction of copper consists of a series of physical and electrochemical processes. Various methods have been evolved with the country depending on the ore source, local environment regulations and other factors. Oxidised copper ores can be treated by hydrometallurgical extraction. The most common ore used in the …
The Extraction of Copper
Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a …
Extraction of Zinc
Earlier days, extraction of zinc was very difficult compared to extraction of other metals because, at temperatures where metals such as iron begin to melt, zinc is in a gaseous state. Due to its low boiling point, at such temperatures, zinc will escape with exhaust gases. Process of Zinc Extraction
