Gold Ore Concentration Operation
The recovery of placer gold involves processing similar to the processing of most ores. First, the valuable material is separated from the valueless waste through concentration. The final concentrate, usually obtained by repeated processing, is smelted or otherwise refined into the final product.
The concentration of placer gold ore consists of a combination of the following three stages: roughing, cleaning, and scavenging. The object of concentration is to separate the raw ore into two products. Ideally, in placer gold recovery, all the gold will be in the concentrate, while all other material will be in the tailings. We provides complete range of high quality small portable gold concentrator.
Small Portable Gold Concentrator
Gold concentrator is a centrifugal bowl type concentrator. The unit is essentially a high speed, ribbed rotating cone with a drive unit. The ore slurry containing 25% to 35% solids is fed into the top of the unit. THe concentrates are retained in the conve until clean-up while tailings are continually washed out from the side of the concentrator. The small portable gold concentrator utilizes the principle of hindered settling classification in a centrifugal force field.
Portable crusher plant is available from a number of manufacturers. These devices perform all the steps of gold concentration: washing, screening, and separation of gold. Additionally, they are easily moved and many have self-contained water tanks for use in dry areas. The small portable gold concentrator for sale includes shaking table, jigging machine, spiral concentrator, centrifugal concentrator, separator etc.
Mini Ball Mill for Gold Ore Processing
We has developed a low cost and energy efficient ball mill grinders for large scale and small scale gold processing operation. The ball mill is a grinder for reducing hard materials to powder. The grinding is carried out by the pounding and rolling of an assortment of high carbonand chromite steel balls carried within the cylinder. The cylinder rotates at a relatively slow speed, allowing the balls to cascade through the mill base, thus grinding or dispersing the materials.
