Advantages of bessemerisation in extraction of copper

general principles and processes of isolation of elementaug 22, 2020· back to course general principles and processes of isolation of element complete. 0% complete. 0/0 stepscopper extraction wikipediacopper extraction refers to the methods used to obtain copper from its ores.the conversion of copper consists of a series of physical and electrochemical processes. methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. as in all mining operations, the ore must usually be beneficiated (concentrated).extraction of copper mining, concentration, smeltingthe copper extracted from this process is mixed with the slag and is called matte copper due to its texture and appearance. this mainly consists of cu2s which is reduced to pure metal by blasting matte copper with air. cu 2 s+o 2 2cu+so 2. the sulphur dioxide escapes the copper and this causes bubbles to appear and burst as so2 leaves. this causes the final product to have a very blistery appearance and hence it is called blister copper;
