Generally speaking, the most commonly used gold concentrator is gravity separator. And the gold concentrator-jig separator is the first choice for gold concentration.
There are placer gold and rock gold of the gold ore. The former density is over 16t/m3 and this leads to a big density difference between gold and the impurities, so gravity separation can be the most efficient, most economical way to beneficiate alluvial gold. The following picture shows the gold concentration site in Xinjiang, China.


For alluvial gold gravity extraction, there are a certain percentage of gravels, and a rotary screen or vibration screen will be needed to remove these gravels. Gold in placer gold is usually liberated from impurities, and the fine sand can be fed to the gold concentrator for concentration directly.

With the development and research of gravity separation plants, chutes, jig separators, table concentrators and gold centrifugal separators have ever turned up, and jig concentrators prove to be an ideal gold concentrator for the first rough separation to gain high grade gold concentrate with its high recovery rate while centrifugal separators and table concentrators work as secondary further gold concentrator. So the whole processing can be screening--gravity separation--shaking table or centrifugal separator. The following picture is about the alluvial gold test of jigging gravity separation:


The most commonly used gold concentrator is gravity separator. And the gold jigging concentrator is the first choice for gold separation and jig separators proved good gold concentrators. Forui gold concentration equipments are of various kinds to meet different requirements.     Forui jig concentrators have been used to beneficiate alluvial gold in Mongolia, Zimbabwe, Congo and many provinces in China. Jig concentrators of JT series, LTA series and trapezoidal 2LTC6109/8T is mainly used as alluvial gold concentrator of gold and tin ore. (PS: Trapezoidal 2LTC6109/8T jiggers have begun to work as tin extraction machine to recover tin from tin sand in Russian since Oct. 2012. )

 Also for rock gold ore dressing, most needs floatation separation to extract. And only quartz gold of coarse gold granules carried by pyrite can be enriched by jig machine. This kind of quartz gold separation is usually bounded to work together with rod milling and classifying as a whole beneficiation process. So the general processing flow sheet can be crushing--rod milling--jigging separation--centrifugal separation or amalgamation.

We have over 20-year experience in designing and and building reliable gravity separating equipment. Our products have excellent engineering simplicity and combined it with highly efficient recovery rates. Good recovery rates and reliable performance make us outstand from all other competitors in the precious metal mining industry. 

We would like to cooperate with you with our high quality gold concentrators and other mining equipment. Your visit to Forui will be highly appreciated for further cooperation. ... Free test can be done with our gold concentrators if samples about 20kg can be available, and detailed flow sheet can be designed with enough details about gold ore known.
