Nov 08, 2016· 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.
Placer Gold Mining Methods. The gold deposits grouped together under the name of “ placers ” comprise sands, gravels, or any loosely coherent or non-coherent alluvial beds containing gold. They have accumulated owing to the action of running water, in the beds of rivers, or on the adjoining inundation plains, or on sea beaches.

A jig is a device that drives pulses of water upwards through a thick bed of settled sediment in order to keep it loose and agitated. This achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. A typical jig consists of a water-filled tank known as a jig-cell, with a horizontal
Jul 18, 2015· Placer deposit or placer is an accumulation of the precious minerals formed by the separation of gravity during the sedimentation process that naturally separate due to gravity and assisted the movement of a liquid medium, solid and gas / air.
