Comminution environment and gold particle morphology

In many laboratories and processing plants, different comminution equipment are used in preparing gold ores for gravity concentration. For malleable metals such as gold, particle shape changes in response to the forces applied during comminution, and these shapes can influence gravity concentration.

Method and installation for extracting gold from gold ore

The invention is directed to a method and apparatus for extracting gold from gold ore by comminution, agglomeration and leaching of the ore. Metallic gold is usually extracted from gold ores by leaching the ore, for example with a cyanide solution, and subsequent recovery from the solution by precipitation or adsorption.
