flotation process in mineral treatment and mining process for concentrating the metalbearing 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
