copper flotation. efd is the leading supplier of with over 170 installations worldwide. our commercial columns are up to 6 metres in diameter, and are being used in most of the world's largest copper concentrators. our range of sparging technologies allow us to choose the right sparging technology for your application.
this was the beginning. when it became clear that froth flotation could save the ‘extremely fine free mineral’ in the slime, with a higher recovery than even gravity concentration could make under the most favorable conditions, such as slime-free pulp, froth flotation forged ahead to revolutionize the nonferrous mining industry.
since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. in gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s hydrophobicity.
the froth of copper-rich bubbles at the top of the tank is then skimmed off for further processing. the gangue sinks to the bottom of the tank to be removed or disposed of as mine tailings. the next stage after froth flotation is the thickening stage. the froth is poured into large tanks called thickeners.
there's gold in ordinary cell phones, along with copper and silver, and the gold is easy to extract. cell phones yield up to 150 grams (15.3 ounces) of gold per ton, compared to five grams per ton
