2. Separation - gravity separation: The principle of gravity separation used for the alluvial gold mining is to separate the gold concentrate from other minerals according to the different ore weight in the original ore. The first step of the gravity process is desliming, which removes the dirt from the mineral.

Gravity separation is a important mineral recovery method and has been the main beneficiation sector used in gold mining plants, alternatively ahead of other processes such as flotation and cyanidation.

The process is still used extensively by artesian mines in third world countries and at small mines, due to its simplicity [4]. Gravity Concentration Gravity concentration processes rely on the principal that gold contained within an ore body is higher in specific gravity than the host rocks that contain the gold [4].

We can supply the whole line of Rock gold gravity processing plant, including: Main Equipment. Jaw crusher, hammer crusher, ball mill, spiral classifier ...

Gravity concentration processes rely on the principal that gold contained within an ore body is higher in specific gravity than the host rocks that contain the gold. Elemental gold has a specific gravity of 19.3, and typical ore has a specific gravity of about 2.6. All gravity concentration devices create movement between the gold and host rock particles in

The process is simple in operation and the processing capacity of the equipment is large. Under the premise that the specific gravity difference is ≥1.25 and the ore monomers are dissociated, the lower limit of the gold particle size of the jig can be up to 0.04mm.

An underground gravity survey was successfully carried out, for instance, in the mining openings of the Katsdag pyrite polymetallic deposit in the Southern Caucasus (Poltoratsky and Ginzburg, 1989) and in the Bazun iron-ore deposit in the Lesser Caucasus (Khesin et al., 1988).
