Panning for gold can be great fun but is not very practical for gold recovery on a large scale. The most cost-effective gold recovery solution for placer deposits is using a gravity concentration circuit. First, the material is screened to remove large rocks and boulders. Then a sluice or jig is used to recover the gold.

If there are only a few parts of gold per 1,000 of the alloy, it has been stated that the silver left in the gold amounts to as much as 3 or 4 per cent.; nevertheless, such an alloy, when subjected in the form of bars to the action of the acid, instead of being granulated, yields gold at San Francisco of no less than 996 fine, after one boiling ...

Rougher, scavenger and cleaner circuits appeared necessary to achieve the very high recoveries required for gold and sufficiently high concentration ratios to facilitate the final recovery step. It was becoming evident, however, that a conventional mechanical cell was inappropriate for such a coarse (minus 0.5 mm) and dense feed.

Gravity concentration continues to be installed in grinding circuits to treat ores that contain free, and particularly coarse, gold in an effort to recover gold as early as possible in a flowsheet, thereby reducing the demands on downstream processes and helping to maximize gold recovery.

This first testing demonstrated that the existing three standard -type crushers could be closed to crush adequate tonnages at one inch (originally 1-½- inch). Also, the installation of 1-inch fine screens in the crusher instead of 1½-inch screens contributed to the flow of finer feed to the rod mill circuits.

Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).
