  • What is the Alluvial Gold Mining Method

    What Is The Alluvial Gold Mining Method

    Nov 12, 2019 The content of alluvial gold in the ore is very low, so in order to extract the gold from the ore, the ore needs to be crushed and ground first, and then the the gold is pre-enriched or separated from the ore by the beneficiation method. Generally, the alluvial gold mining concentrator mostly uses jaw crusher for coarse crushing and cone crusher for medium crushing. 2. Separation - gravity separation The principle of gravity

    Alluvial Gold Mining Cde Global

    Alluvial gold usually takes the form of dust, thin flakes or nuggets. The first stage in alluvial gold mining is to take the dredged river bed material and separate the small sand faction (where the gold is found) from the larger mineral fraction. In a typical alluvial mining process physical separation methods such as screening and gravity separation are employed to separate the gold from the mineral fraction.

    The gold that these rocks contained has been washed down into creeks to form alluvial (placer) gold deposits. Here, the gold is further concentrated by the action of water. Because gold is heavier than most of the material moved by a creek or river, it can become concentrated in hollows and trapped in the bed of the river.
