1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry The particles with attached air bubbles are then carried to the surface and

Most of the copper ores contains only 0 4 -0 6 copper and other valuable metals as coproducts or byproducts, including molybdenum, silver, gold, bismuth, cadmium, and cobalt Copper Ore Mining Process For many sulfide copper minerals, the removal of copper is ultimately accomplished with fire, so it is known as a pyrometallurgical process
