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.
Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.
The gold ore process is usually determined by the physical, chemical and mineralogical properties of gold ore and gangue. For example, gold ore with a large difference in specific gravity and coarse grain size is generally treated by gravity separation.JXSC gravity separation equipment mainly includes spiral chute, jig and shaker.
