Methods of concentration ores like magnetic separation and froth flotation method and other names of the ores concentrated by th

concentration of the metal of interest or its compound in the ore. Several methods are available for this process and the choice of method will depend on the nature of the ore, type of impurity and environmental factors. Some of the common methods of ore concentration are discussed below. 1.2.1 Gravity separation or Hydraulic wash
