When an ore is extracted it appears in rock form and it contains a concentration of minerals which occur naturally and contain metallic elements These rocks must be crushed to have the copper extracted this process is called comminution Typically there is a small percentage of copper bound in an ore the rest is considered gangue otherwise known as the worthless minerals that are

Sponge iron is the product created when iron ore is reduced to metallic iron in the presence of coal at temperatures below the melting point of iron The external shape of the ore is retained with 30% reduction in weight due to oxide reduction resulting in change in true density from gm/cc to gm/cc in this product

Hydrometallurgy refers to the application of aqueous solutions for metal recovery from ores and has been practiced for copper recovery for many years The original impetus for solution methods for copper extraction before the development of froth flotation technology was the existence of large ore bodies of low copper content which were uneconomic to work using conventional smelting methods
