copper flotation new

Mining produces ores with less than 1 percent copper Concentration is accomplished at the mine sites by crushing grinding and flotation purification resulting in ore with 15 to 35 percent copper A continuous process called floatation which uses water various flotation chemicals and compressed air separates the ore into fractions

Flotation Frothers What is the Function of Frothers The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the nonfloatable minerals Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form
