FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

size, gravity separation, cyanidation and flotation, all of which increase capital and operating costs. In some cases, oxidation of sulphide minerals is needed to liberate gold that is occluded within the sulphide matrix. Sulphides can be oxidized by several methods, and the overall costs are similar.

Gold Mining Process Development Denver Mineral Engineers

The prospector’s gold pan is the most familiar gravity concentration device. To function properly, the ore must be broken down to particles small enough to provide a significant specific gravity difference among the particles. Placer mining has generally been where gravity concentrates have been most widely applied.

Major Mines & Projects Aureus East (Dufferin) Mine

Saleable gold products from the site are doré bricks and flotation concentrate. About 85% of the recovered gold will be in the form of doré bricks which will assay about 80% gold and 20% silver. The remaining 15% of the gold that is recovered will be in a flotation concentrate assaying between 30 grams/tonne and 300 grams/tonne.

GRAVITY CONCENTRATION OF GOLD FROM CYCLONE

Where there is gravity recoverable gold, it is important that it be maximized, as the unit operating cost for a gravity circuit is much lower than that for any other process. Minimizing the Size of the Gravity Concentration Circuit Many process engineers view gravity concentration in gold grinding circuits as a nuisance and a security risk.

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an
