How to profit from low-grade gold mines - Part 1 | Kitco News

The most commonly used process to extract gold is cyanide leaching, based on a chemical reaction first identified in 1894 by L. Elsner. A slurry of ground ore is mixed with cyanide in the presence of activated carbon. The carbon adheres to the gold, which is then stripped out at high temperature and pressure to form an electrolyte solution.

Extracting Gold | HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

Advantages Of Using Gravity Concentration For Gold Recovery

Using gravity concentrators can help mitigate the nugget effect by extracting the gravity recoverable gold (if there is any), leaving a homogeneously graded material ready for downstream processing. If there isn't any gravity recoverable gold, you can be sure that you'll get the best recovery from your chemical processes.
