Copper Mining and Extraction Sulfide Ores

From the formula it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 C and 700 C in air.

Copper can then be extracted from the copper II sulfate solution. But in many cases it is possible to separate the metal compound from unwanted rocky material by physical means. A common example of this involves froth flotation.

Copper Mining and Production Processes Explained

An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding. The ore is crushed then ground into powder. Concentrating. The ore is enriched using a process called froth flotation. Unwanted material called gangue sinks to the bottom and is removed. Roasting. This is where the chemical reactions start.

These chemicals are used to extract the copper sulfides from the other materials in the slurry. This is done by a process called froth flotation where the copper sulfide particles attach to air bubbles and rise to the surface. This is then skimmed off the surface and sent for smelting which creates pure copper. Related Articles. Who
