20 TPH alluvial gold mineral wash plant GT1020 Trommel screen STL 60 Centrifugal concentrator
For Placer gold, they don't need to be crushed.
Compared with vein gold mines, they can save a lot of equipment investment and operating costs.
The preparation of ore before gold selection is mainly screening, grading and washing.
In order to separate the ore into individual particles and completely separate the valuable mineral particles,
the placer gold ore also needs a disintegration operation, but generally does not require a separate process.
If the placer gold deposit is mined by hydraulic method, the crushing operation of the ore will be basically completed during the mining process.
When other mining methods are used, the decomposition and grading of the ore and the washing operation are often performed in the same equipment (for example, a flat screen or a drum).
The ratio of the largest grain size of the placer gold to the smallest grain size of the placer gold can reach several thousand times.
Large pieces of gravel usually do not contain gold. Through the classification operation, the metal-free boulders and gravels can be separated, thereby greatly reducing the volume of candidate materials.
The disintegration operation requires a certain amount of power. The power consumption per unit weight of material is a standard for the intensity of the crushing operation of certain equipment. The more sticky the material being processed, the more power I need.
Placer gold ore is usually divided into easy-washable (gravel-pebble) ore, medium-washable (with small amount of clay) ore, and difficult-to-wash argillaceous (including A lot of clay) ore. Production practice shows that in the placer gold beneficiation process, ore washing and grading are very critical links.
The ore washing is not clean, the metal loss is serious, and the mud ball destroys the separation operation, resulting in a reduction in the recovery rate and gold production. Classification is not good, coarse and fine-grained mixed selection, the selection effect is not good. Based on a systematic analysis of the grain size composition of the ore and the distribution rate of gold, a practical ore washing and grading scheme should be formulated in accordance with the specific conditions of each ore site.
The main machine for a set of alluvial gold wash plant
1. Trommel screen
If you need the mobile-trommel, we can also make.
2. sluice box with gold carpet
Some clients choose build the sluice box by themselve, and only buy the gold catching carpet.
3. Centrifugal concentrator
5. Some time, A shaker table also can be necessary to improve the purity of minerals.
