Concentrator. The ore is mixed with an aqueous solution and ground into a fine powder. It is then mixed with water, chemicals and air in flotation cells. This process causes the copperbearing minerals to stick to air bubbles in the cells. When the bubbles float off the top, they are collected as a liquid concentrate that is 28 per cent copper.
