What is the Alluvial Gold Mining Method?

2019-11-12 · The principle of gravity separation used for the alluvial gold mining is to separate the gold concentrate from other minerals according to the different ore weight in the original ore. The first step of the gravity process is desliming, which removes the dirt from the mineral. The second step is to screen the larger stones and remove them by ...

2020-3-26 · Jig separation has requirements on the particle size and content. The particle size is usually 10%-15% under 0.2mm. The raw ore should be with gold between 25-300mg in a cubic meters. Under this condition, the gold above 0.2mm can be recovered. Compared with spiral chute, jig separation has higher gold recovery rate in alluvial gold mining.
