Gold Extraction / Mining |
Extraction of Gold using the Borax Process. The borax process is also an environmentallyfriendly method of extracting gold. Here the goldbearing rock material is placed in a melting crucible and then borax (sodium borate) is added. The borax sinks the melting point of the ore mixture and makes the molten mass more fluid.

Gold processing
For extracting gold from lowgrade ores, heap leaching is practiced. The huge heaps described above are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. Immense amounts of solution and solids are associated with a vat leaching circuit, owing to the very low concentrations of gold in the ores. In order to eliminate the huge ...
Extraction of gold using cyanide
Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble. To make gold soluble sodium cyanide (NaCN) is added and the ...

Extract copper and gold from lowgrade ores ...
Extract copper and gold from lowgrade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance, approximately 1520 per cent of the world's current gold production involves refractory ores that must be pretreated prior to downstream recovery by cyanidation.
Extraction of Gold
The ore is reduced to a fine state of division and amalgamated simultaneously in a stampmill, the solid goldamalgam separated from the liquid mercury by filtration through leather under pressure, and the mercury distilled. Complete extraction of the gold by amalgamation is impossible, a part remaining in the mud of the stamp mills. Concentration is effected by washing, and the ...

Gold Extraction Recovery Processes
· The process is characterized for its economic cost against the agitated leaching process when the ore deposit has a low gold content. Typically the process can process ores whose gold content is g/t. The leaching solution is spread at the top of the pile and the pregnant solution will have to percolate through the pile. The design considers special drainage pads for pregnant liquid ...
