Alluvial gold equipment is from containing gold river sand, dry sand beach, the loose rock clastic sediments using gold by gravity, the hydrophilic mixed with other physical properties of a substance are different and by gravity concentration, flotation technology to separate gold equipment.

The characteristics of alluvial gold equipment

Fixed chute: the advantages of fixed chute is does not need power, the cost of production base, simple operation, to more than 0.2mm recovery of coarse gold. The disadvantage is the intermittent operation, the labor intensity of workers, fine gold recovery effect is poor.

Chute: is the fixed chute choose gold principle, fitted with a rubber plate agitating device, with mechanical agitation plate and the bottom plate under periodic agitation, prevent sediment compaction, periodic agitation, complete the stratification and sediment and improve the recovery rate of gold. Chute, very good for the skin capillary gold and gold effect and has the advantages of simple structure, reliable operation, less failure, low energy consumption, water consumption is a kind of alluvial gold practical equipment.

Water jacket centrifuge: strengthen the gravity separation equipment using centrifugal principle. In high times enhanced gravity field, gravity difference in the proportion of large and small proportion of mineral is greatly enlarged, which makes the separation between light and heavy minerals more easily than the natural gravity field; and special design of material bed layer structure, with patented technology of flowing water and interaction of interference settling, continued to maintain a loose state. Under the above conditions, heavy mineral particles can replace the light mineral particles in the selection of the location of the bed occupied and retained, light mineral particles are discharged as tailings, so as to achieve the separation of mineral particles according to the specific gravity. This equipment is widely used, running ore less, is a new type of gold separation equipment.

Hop jig, jig is earlier gravity separation equipment, hop jig working principle based on gravity separation, poor sorting by the proportion of ore and gangue and different heavy mineral raw materials in the vertical alternating current settlement speed is different, a larger proportion of mineral settling faster, occupy the jump in the lower part of the jig separation tank, the smaller proportion of the mineral settlement slower, occupy the upper part of the separating tank, special weir plate through the weight of different minerals were discharged, achieved by the effect of gravity separation. Jigging separation for alluvial gold particles larger.

Table: table separation effect is very good, but the weak processing ability. The table parallel or multi-layer use can solve the above problem, but increase the cost of production. The table is generally used in two selected alluvial gold in.

Flotation machine: the flotation process is more complex, with crushing machinery the gold bearing minerals are crushed to the appropriate size of flotation, flotation reagents are added into the pulp and to adjust pH value, to the flotation machine rushed into the air, bubble formation, small gold particles attached bubbles and with the bubble to form foam layer, the flotation machine to gold foam scraped finish flotation.

Amalgamator: the amount of mercury and gold bearing grains in the amalgamator and mixing, pro mercury gold was wrapped in mercury and separated from other substances, the gold amalgam mercury extrusion and alluvial gold separation. Due to the toxic and expensive price of mercury, affecting his use. Amalgamator generally used in combination with a chute for separation of gold, gold for the heavy sand chute.

Roller: tailings elected in amalgamation method, and some gold and other sand mixed ore. Roller is the ore grain crushing equipment. It is simpler than the lowest and the use of ball mill, is in favor of some small concentrator.
