This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. 92;(Cu^{2}S + O^{2} 2Cu + SO^{2}92;) 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; 98 99.5 % pure.

    Copper 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. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals, the ore is crushed and ground to li

    How copper conducts Copper is a metal made up of copper atoms closely packed together. If we could look closely enough, we would see that there are electrons moving about between the copper atoms. Each copper atom has lost one electron and become a positive ion. So copper is a lattice of positive copper ions with free electrons moving between them.
