The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Froth flotation is a process used to concentrate copper sulfide ores. Ground ore is mixed with water and reagents, making copper minerals hydrophobic. Air is pumped into the mixture, creating bubbles that cling to the copper minerals and carry them to the surface. The froth, rich in copper, is skimmed off, leaving behind waste material. ...
