Extraction of metals from ores diffesale processes involved,this is one of the methods of extraction of metals from ores by using two mediums together. both oil and water are used to separate impurities. It can only be done when the ore forms froth when compressed air is passed in this medium. the frothed ore collects on the oil section whereas the impurities settle down in the water medium.
