Alluvial Gold Processing Plant
For alluvial gold, also called sand gold, gravel gold, placer gold or river gold. it is suitable for Gravity Separation. Achieve optimal gold recovery with minimal impact on the environment. Henan Victory gold washing process enables sustainable and cost-effective gold recovery >90%.
Application
Alluvial gold processing mainly applies to processing alluvial gold contains mainly free gold blended with sand or soil. Under this circumstance, the main process is to wash away the mud/soil, and screen out big size stones/gravels with trommel screen, then using Jig machine or Gold concentrator, shaking table, as well as the gold carpet to separate the free gold particles out from sand or soil.Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.
The specific process is as follows:
Crushing and Screening
Many alluvial gold ores contain cementing mud and most of its particle size is over 100 mm, if not being crushed, it will be discharged together with the waste rock in the process of screening, thus,it will take the loss of gold. The trommel are the commonly used screening equipment, which has long service life and high processing capacity.
Desliming
Material less than 0.1mm almost does not contain gold in alluvial gold ore, which is called floating gold and it is difficult to be recovered in the separating process. Also, the gold and sludge will be confused in the separating process, especially in the mechanical separating process. so, in the alluvial gold mining process, this kind of sludge mainly be eliminated. so it need the Desliming equipment, that is an off-the-mud bucket.
Separating
It has proved that gravity separation is the most effective and economical alluvial gold processing method. Due to the different sizes distributed among alluvial gold, different alluvial gold processing equipment has various effective size limitations, so a reasonable alluvial gold separating process should apply the several gravity separators to jointly operate.
