    The ground ore is mixed with water to form slurry which chemical reagents are added and then aerated to produce bubbles. Using the principle that the hydrophobic ore particles attach to the bubbles the target ores are recovered. From this process copper concentrates with 20-40 -Cu is produced which is sent to a smelting and refining plant
