A typical application for a Falcon SB Gravity Concentrator is recovering liberated precious metals (Au, Ag, Pt, etc.) within a grinding circuit. Outside grinding circuits, Falcon SB Gravity Concentrators are also used for precious metal separation from aggregate or placer deposits.. Falcon SB Gravity Concentrators are known as “Semi-Batch” Gravity Concentrators because they continually ...

Where there is gravity recoverable gold, it is important that it be maximized, as the unit operating cost for a gravity circuit is much lower than that for any other process. Minimizing the Size of the Gravity Concentration Circuit Many process engineers view gravity concentration in gold grinding circuits as a nuisance and a security risk.

Using gravity concentration to optimize gold recovery is now a necessity in today’s competitive mineral industry.. At Sepro, our goal is to help you squeeze out every ounce of gold from your recovery circuit. While froth flotation and cyanide leaching both play major roles in gold recovery, the benefits of using gravity concentrators cannot be understated.

Gravity concentration. Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as ...

The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious metal is ...

In many instances, it is most profitable to recover the gold in the form of a concentrate, and either ship this product to a smelter, or amalgamate or cyanide the concentrates at the mine. In other cases, flotation has been utilized to recover the values remaining after amalgamation or gravity concentration.

Essentially, a gravity table is a mechanized gold pan, that operates with a high degree of efficiency and continuously. The table is comprised of a deck, in somewhat of a rectangular shape, covered with riffles (raised bars running perpendicular to the feed side of the table), mounted in a near flat position, on a supporting frame that allows the table to slide along the long axis of the table.

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. However, froth flotation processes may also be used to concentrate the gold.
