The Knelson Concentrator is a compact hatch centrifugal separator with an active fluidized bed to capture heavy minerals. A centrifugal force up to 60 times that of gravity acts on the particles, trapping denser particles in a series of rings (riffles) located in the machine, while the lowdensity particles are flushed out. ...

The purpose of the concentrator is to reduce that percentage so that it can he economically he shipped to, and treated by, a smelter. To accomplish this the mineral must be liberated, prepared, separated and finally dried for shipping. The first stage, liberation, takes place after the ore is taken from the mine.

Introduction: Jig concentrator (jig separator, jig machine) is a equipment that drives pulses of water upwards through a thick bed of settled sediment to keep it loose and achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. A typical jig consists of a waterfilled tank known as a jigcell, with a horizontal ...

In generals, the concentration of gold includes three stages: roughing, cleaning and scavenging. The reason of concentration is to separate the raw material into two products, concentrate and tails. Ideally, in free gold recovery, all the gold will be in the concentrate and the other part will be in the tails.

Unlike a concentrator with multiple grinding lines, conducting SAG mill maintenance shuts down an entire concentrator, so there is a tremendous focus on minimizing required maintenance time; the reline timeline often represents the critical path of a shutdown (but typically does not dominate a shutdown in terms of total maintenance effort).

So for a couple reasons, 1) screen efficiency and 2) concentrator efficiency, we want to get that concentrator in the feed because it's a more dilute stream and we can get closer to this 45%, 50% solids range. Especially once we include the spray water for the screen, we can get this to a good point where the concentrator is going to be ...
