sluicing in mineral processing

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Stone production line

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Sluicing mining Britannica

In placer mining. In sluicing or hydraulicking methods, a slightly sloping wooden trough called a box sluice, or a ditch cut in hard gravel or rock called a ground sluice, is used as a channel along which gold-bearing gravel is carried by a stream of water. Riffles

Principles of sluicing - ScienceDirect

01/10/1985  Sluices of different forms have been used for the separations of denser minerals for centuries and it is perhaps the oldest technique of gravity con- centration employed in mineral processing. The action of sluicing is observed in nature too -- exposure of heavy minerals in the mineralized areas after a heavy down-pour, heavy sands concentration on the beaches by tidal action and the removal of materials by river action, are the classical citations. The earliest models of sluices ...

Pinched Sluice - Metallurgist Mineral Processing Engineer

08/11/2016  Pinched sluices have been used for heavy-mineral separations for centuries. In its elementary form, the pinched sluice is an inclined trough 2 to 3 feet long, narrowing from about 9 inches in width at the feed end to 1 inch at discharge. Feed consisting of 50-65% solids enters gently and stratifies as the particles flow through the sluice and crowd into the narrow discharge area. Heavy minerals

Gold Sluice Box Design - Metallurgist Mineral

09/09/2015  Small-scale sluicing by hand methods has been called quite appropriately shoveling-into-boxes. In contrast, in ground sluicing, usually a more efficient operation, most of the excavation is accomplished by the action of water flowing openly over the materials to be mined. In either case, the materials pass through a sluice, where gold is collected behind riffles. A variation of the sluicing ...
