Gold Processing Methods & Gold Ore Extraction

The feed gold and silver was amenable to gravity separation and flotation. However, the subsequent cyanidation of the concentrates did not provide any significant improvement, on average, over Whole-of-Ore CIL testing. The gravity/flotation flowsheet with cyanidation of the respective concentrates recovered between 30 and 77% of the gold in feed, with an average of about 59 percent across all ...

How Is Gold Extracted From Gold Ore? | Sciencing

Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury gas is highly toxic and must be handled carefully.

Gravity Concentration | Gekko

The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises over-grinding and prevents losses due to excessive ...
