mar 18, 2019 introduction. In its simplest definition, gravity concentration is a class of methods which take advantage of the density differences among mineral particles .as a result, particles of which densities are different from each other have their own relative movement against the forces of the gravity depending on the factors such as viscosity of the environment, resistance to the motion in
the specific gravity of gold is 19.3, so it is 19.3 times as dense as water. when separating free gold from a typical quartz deposit, gravity concentration must separate based on specific gravities of 19.3 and 2.6, for gold and quartz respectively. the gravity concentration separation process gets more complex as the specific gravities between
knelson concentrator is a gravity-based centrifugal fluidized bed separator in which fine particles are separated by application of centrifugal force based on their specific gravity. centrifugal field of about could be achieved in this type of separator. this unit is widely used for recovering gold particles in

prior continuous discharge centrifugal concentrators for separating higher density particles from a slurry have used pinch valves to control the flow of discharge. such pinch valves tend to be blocked by coarse particles, requiring shutdown of the machine. the present invention provides a muscle-type valve to provide a circular orifice for the valve bore of continuously variable perimeter.
gold refining shaking table as one of gravity mining equipment, shaking table is widely applied on separating gold, manganese, chrome, lead, zinc, mercury, auluminum and rare metals, the noble metal ore, also applied on sorting coal, ect. shaking table can be usedin different stages in mining, like rough concentration, retreat and scanvenging.
during the separation process, the adjustable-frequency blower supplies air-flows with different speed and quantity; due to the specific gravity and particle size differences of the sand and gold, the effects of gravity force, wind resistance and wind thrust force to the sand and gold are also different, the displacements of the sand and gold are therefore different in the horizontal direction.
flsmidth knelson concentrators are the market leaders in gravity concentrators, and are worth more than their weight in gold. using centrifugal force and water injection processes, flsmidth knelson concentrators create enhanced gravitational forces of up to 200 gs to recover free gold, fine gold and any other precious metals or minerals with high specific gravities.
supply various specific gravity concentrator for gold. spiral separator for gold. spirals are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
concentrating tables are comprised of wooden decks, rectangular or diagonal shape, with ultra-smooth rubber cover and riffle surface and are operating in horizontal plane, where material with higher specific gravity is separated from material with lower specific gravity.. head motion imparts a reciprocating movement to the tables deck in a horizontal plane.
prior centrifugal concentrators for concentrating precious minerals use annular ribs or baffles to trap the precious minerals. sand or magnetite tends to pack against such ribs, reducing the effectiveness of these devices. In the present invention, the inner surface of the rotating drum is free of obstacles, but forms three continuous zones, a migration zone, a retention zone and a lip zone.
the semi-continuous knelson concentrator is the most widely utilised centrifugal gravity concentration device in the industry. knelson concentrators combine centrifuge enhanced gravitational force with a patented bed fluidization process to provide unmatched performance in the recovery of precious metals such as gold and fine gold, platinum, silver, mercury and native copper.
