Jun 23, 2021 Some of the common methods of ore concentration are discussed below. Gravity Separation or Hydraulic Wash. In this method, the ore having high specific gravity is separated from the gangue that has low specific gravity by simply washing with running water. Ore is crushed to a finely powdered form and treated with rapidly flowing current of water.
Sep 19, 2019 Heavy media separation is a gravity separation process that crush ores into a certain size, and make the density of the fluid heavier than water (that is heavy medium). According to the Archimedes principle of buoyancy, when density is less than media, ore particles will float when the density is greater than media, ore particles will sink.

According to the density difference among mines and the difference of gravity, fluid power and mechanical force in moving medium, mines realizes mineral grains separation through density difference, it still occupies an important position in the contemporary mineral
The Froth Floatation method is a method used for the concentration of metal ores. It is used for the concentration of sulphide ores. In this method, water is added to powdered ore. To this, substances called collectors (such as pine oil ) are added so that the ore particles can be separated from the gangue particles. The ore particles become ...
Concentration of ores is also known as enrichment of ores. Process of concentration depends upon physical and chemical properties of ores. Gravity separation, electromagnetic separation, froth flotation process , etc. are some examples of the processes which are applied for concentration of ores.
The choice of method depends on the nature of the ore. Some important methods are (i) Gravity separation (Hydraulic washing) In this method, the light (low specific gravity) earthy impurities are removed from the heavier metallic ore particles by washing with water. It is therefore, used for the concentration of heavier oxide ores, like ...
