  Phosphate Beneficiation - Florida Polytechnic University

  Flotation separates valuable minerals (copper, lead, zinc, iron, and phosphate too) from the contaminating minerals in the ore (sand in this case). In the direct flotation process the valuable mineral is coated with a special hydrocarbon (fatty acid) that makes coated particles behave the same as a waxed car.
