Roasting is a technique by which carbon and sulfur react with metal to separate the ore for example copper acetate is reacted with chemicals to separate the copper ore and residue this mix is reduced which involves placing it under extremely high temperatures injecting a reagent such as hydrogen or carbon dioxide and melting away the metal
Copper minerals and ore are found throughout the earths crust they occur in both sedimentary and igneous rocks the outer 10 km of the crust contains 33 g of copper for every tonne of rock this is not enough to make it commercially viable to extract the rock
After the copper ore is crushed liquid is added to make it a slurry the slurry is a mix of valuable copper ore minerals and worthless rock called gangue pronounced gang the slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue chemical reagents called collectors are added to the slurry and bind to the copper particles making them
To separate the ore from the waste rock first the rocks are crushed then the minerals are separated out of the ore there are a few methods for doing this heap leaching the addition of chemicals such as cyanide or acid to remove ore this is often done at very high temperatures
In order to separate the valuable components of an ore from the waste rock the minerals must be liberated from their interlocked state physically by comminution as a rule comminution begins by crushing the ore to below a certain size and finishes by grinding it into powder the ultimate fineness of which depends on the fineness of dissemination of the desired mineral
It is the area where the waste rock and ore are separated they add more oxygen o2 for the smelting process to operate at a higher temperature the bubbles trap sulfur from the crushed rock to enrich the remainder in copper the bubblers are used in the waste pile rocks this problem has been solved
