flotation process mining

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore . Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

    Mining Flotation. Flotation is an incredibly robust and versatile process that is well accepted around the world. It works equally well on mixed sulfide, oxide, silicate and other ores. It relies on generating a population of bubbles of suitable size that can carry the hydrophobic target mineral (usually but not exclusively sulfide minerals)...

    Flotation Machines | Mineral Processing Machine

    Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

    Copper Mining and Processing: Processing of Copper Ores

    After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and “worthless” rock, called gangue (pronounced “gang”). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.
