Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare-earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.

Such tables are termed tables. The ore is continuously washed with a fine spray of water and the rocking motion sieves the heavier portions, while allowing the impurities to filter away. Fig: 10.2 - table for washing of the ore. Sometimes in the gravity method, a hydraulic classifier based on the gravity method is used.

The pulverized ore is separated by hydraulic washing, froth-floatation process, magnetic or chemical process, depending on the nature of the ore and its impurities. Concentration of the ore is also known as dressing of the ore or enrichment of ore. Concentration of an ore is the process of removal of impurities from the ore.
By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind. For this, either table or Hydraulic classifier is used. Generally oxide and carbonate ores are concentrated by this method. i.e. haematite and cerussite. There are two gravity concentration methods.
(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 haematite Fe O2 3 tinstone SnO2 and gold (Au). In this method, as shown in
Jul 06, 2017· 5.ExplainGravity separation process or hydraulic washing This method is especially suitable for heavy 'oxide' ores like haematite, tinstone, etc. In this, the powdered ore is placed on a sloping floor (or platform) and washed by directing on it a strong current of water. The lighter sandy, and earthy impurities are washed
