Simply put, pre-concentration drastically reduces the ore mass that reports to intensive downstream processing. By using gravity to recover mineral-bearing particles into a much smaller volume, significant savings in energy and operational expenses are achieved.
It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore. The concentration criterion is commonly used for this purpose, designated in the following equation (where represents specific gravity):

At first the ore is crushed to powder. The pulverized ore is separated by physical processes like hydraulic washing, froth-floatation, and magnetic separation or by chemical processes, depending on the nature of the ore and its impurities. Concentration of the ore is also known as 'dressing' or 'enrichment' of ore.

There are numerous methods of concentration and the methods are chosen based on the properties of the ore. Hydraulic Washing: This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic ...
Multotec's Gravity concentration equipment is an efficient, low-energy classification solution used in coal, copper, iron ore, chrome, mineral sands and gold processing.

baichy gravity concentrators for gold and silver extraction. Gravity concentration is the separation of minerals based on differences in specific gravity A gravity concentration process is designed to recover very high grades of valuable ore material .
Oct 12, 2018· The 'concentration criteria' (CC) gives an idea of the amenability of separation of two ore particles and can be expressed by (Dh-Df)/(Dg-Df) where Dh is the specific gravity of heavier component of the ore, Df is the specific gravity of the fluid medium, and Dg is the specific gravity of the lighter component of the ore.
In the method we use to How to Find and Determine Specific Gravity of Rocks (some call it Specific Density because they don't know better!), we'll use simple equipment. What is required to make this measurement is a weight scale, and the list of the different minerals SPECIFIC GRAVITIES. What specific gravity is, is the mass of a solid in relationship to its weight.
CHAPTER-7 GRAVITY CONCENTRATION OF IRON ORE R. K. Rath and R. Singh INTRODUCTION Gravity concentration process is the oldest beneficiation method known to mankind. This is a physical process and exploits the differences in densities of minerals to bring about a separation.
Copper ore weighs 2.265 gram per cubic centimeter or 2 265 kilogram per cubic meter, i.e. density of copper ore is equal to 2 265 kg/m³. In Imperial or US customary measurement system, the density is equal to 141.4 pound per cubic foot [lb/ft³], or 1.309 ounce per cubic inch [oz/inch³] .
