purification of copper by electrolysis metal extraction

Copper is extracted from its ores by chemical processes that involve heat or electricity (roasting ores in a smelter–furnace and purification by electrolysis all the details below). Because of its position in the reactivity series of metals, less reactive copper can be extracted using carbon in a smelting furnace.

The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore: The ore is crushed into a fine powder and a suspension is

Copper: Copper is an amazing metal. All the electricity and you are enjoying now is due to copper. The electricity cables are made of copper. Copper is even embedded inside electrical devices such as power circuit boards to conduct electricity. In some countries, copper is used to making hot water pipes as they do not react with water. The coaxial cable of your TV also has copper inside it

Extraction Of Metals Definition, Factors & Occurence

These metals are economically and conveniently extracted from these ores by following certain extraction techniques. The reason behind presence of metals in form of ores and minerals is that, most of metals being highly reactive, cannot exist in free form [6]. Ores have usually high traces of metals to be extracted and that’s why these ores are of major importance in metal industry. Table
