Froth floatation is perhaps the most well-known method for eliminating minerals from rocks and materials. Frost floatation separates economically significant minerals from different minerals and pollutants in metal/mineral handling. The minerals are gathered on the outer layer of a thick layer of foam called a “froth layer.”.
