Gold Extraction and Recovery Processes

Gold Extraction Methods Although new process are being proposed on a regular basis, there have in fact been no dramatic changes in the metallurgical techniques for gold extraction since the introduction of the cyanide process (cyanide leaching or cyanidation) by McArthur and Forrester in 1887 [2].

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 …

Gold extraction process

As the gold is in bullion or ingot form, its surface area is small, so the amalgamation process will take a while to occur. Chopping up the gold bar will help speed up the amalgamation process. As gold has similar atom size compared to mercury, the two elements can easily form a …

However, tailings from this process are often repeatedly run through the ball mills. Each time more auriferous, or gold-laden, mercury stone is produced.

Gold Processing Methods & Gold Ore Extraction

Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page ...

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.
