Sustainable Responsible Mining I Cyanide-Free Gold

The Clean Mining gold recovery process, developed by Australia's CSIRO, replaces cyanide and mercury with a safer, less hazardous chemical reagent. This alternative gold recovery solution is non-toxic and dissolves fine gold out of ores into a solution, which can then be recovered through further processing. INNOVATIVE SOLUTION. What is our non-toxic solution? This gold recovery agent is an

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. In these drums, the ore is ground to a fine slurry or powder.

3 Technologies in Exploration, Mining, and Processing

In gold plants, for example, a number of gravity devices, old and new, are being used to recover relatively coarse gold. Over the past few years gravity separators that take advantage of differential specific gravities in a high-gradient centrifugal force field (e.g., Knelson and Falcon separators) have been used successfully for gold.
