The Extraction of Copper - Chemistry LibreTexts

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 sili e carbonate or sulfate ores. Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of

Extraction of copper from copper pyrites CuFeS2 Mastering

2. Copper pyrites is converted to a mixture of Cu 2 S and FeS 2CuFeS 2 O 2-----> Cu 2 S 2FeS SO 2 3. The sulphides of Cu and Fe are partially oxidized 2Cu 2 S 3O 2 <=====> 2Cu 2 O 2SO 2 2FeS 3O 2 <=====> 2FeO 2SO 2 Smelting in extraction of copper The roasted ore mixed with silica as flux is heated in a blast furnace by a blast of

Notes OCCURRENCE AND EXTRACTION OF METALS

involved in the extraction of metals from their ores are : i Crushing and pulverization ii Concentration or dressing of the ore iii Calcination or roasting of the ore iv Reduction of metal oxides to free metal v Purifi ion and refining of metal. 16.2.1. Crushing and Pulverization The ore is generally obtained as big rock pieces.

Copper: Occurrence principles of extraction Properties and Uses

The chief ore of copper is copper pyrite. It yields nearly 76% of the world production of copper. Extraction from copper pyrites. Extraction of copper from copper pyrites involves the following steps. 1. Crushing and concentration. The ore is crushed and then concentrated by froth-floatation process. 2. Roasting.
