CrushingCrushing involves tipping ore into a large crushing machine. The swinging weight of the crushing machine compresses and fractures any large or small rocks into smaller rocks. 50% of the rocks from this process are smaller than your fist in size.The smaller rocks are dropped onto a large travelling rubber belt conveyor. Conveyors are good at deliveries rocks quickly to large stockpiles.

GrindingGrinding is the process that breaks fist size rocks to very fine particle sizes. This is done in large SAG mills or ball mills.The size of rock particles after milling is less than 1/5 of one millimetre. To break rock to this very fine size involves using a lot of electrical power. The SAG mill alone uses 12 megawatts of power (enough to operate all the homes in 2 small towns).All rock particles formed during grinding now travel with water added to the mills. This mixture is called a slurry. The slurry from milling is transported around the treatment plant by special pumps.

FlotationThis process uses chemicals to collect both Phosphate  into a concentrated form.Special chemicals are added to the slurry from grinding. These attach themselves to certain minerals in the slurry. All the slurry is pumped to large tanks called flotation cells. Air is added to the bottom of flotation cells and rises through the slurry. The chemicals added earlier are hydrophobic so they attach themselves to the passing air bubbles and float to the top of the cell. When the air bubbles reach the top of the cell they form a froth much like the top of a cappuccino. This froth contains nearly all the Phosphate .
