Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by …

Alluvial gold mining method and equipment in the gravity separation process: 1. Pre-separation: Compared with other ore processing, the pre-separation before the alluvial gold mining is not complicated. It is mainly to remove the mud from alluvial gold ore or make the grain size meet the requirements of separation operation. The …
The first stage in alluvial gold mining is to take the dredged or excavated feed material and separate the small sand faction (where the gold is found) from the larger mineral and rock fraction. In a typical alluvial mining process physical separation methods such as screening and gravity separation are employed to separate the gold from the ...

In addition to the under level in our deepest and most difficult alluvial mines, an upper level should be constructed in the bed-rock, for three very important reasons. First, to provide an escape for the men in case the mine should be flooded; secondly, as a return air course; thirdly, to tap the water by boring, at a higher level, where the ...
