Cyanide method has a history of more than 200 years since it was used in extracting gold and silver in 1887. With the high recovery rate, strong ore adaptability, fast extracting speed, cyanide method is still one of the main gold extraction methods.

4) Final recovery of gold from concentrate. Processing - Grinding An important output from the testwork was to determine the optimal grind size to liberate gold contained in the ore. Grinding (or milling) of ore takes place in a ball mill and is the most expensive and energy intensive part of the process.

The finer particles receive more grinding in a ball mill, and are size classified to give a final product of 80% < microns. See more detail on grinding and sizing. 5. Leaching and adsorption A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold …

IsaMill Operating Principles. The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills).Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents ...

A hypothetical ore is crushed to a size of 15,000 microns, ground wet in a rod mill to 1000 microns, and then ground wet in a ball mill to the various micron sizes of 300, 250, 200, and 100. In this example the product size represents the size in microns which 80% of the product passes.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Garry Jackson Alec talking of ball mills,have you seen the ball mill up at the globe mine at reefton in action.Was interesting seeing it started for the first time,,hate to think hows many amps it hauled on start up,the old clutch smoked a bit.With it rotating in a clockwise direction we wondered how far it would travel down the hill if there was ever a major earthquake and it came adrift.
