FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

crushing, followed by dump or heap leaching with cyanide. Gold recovery is usually around 80%, but can be as low as 60%. Recoveries can be improved to 95-99% by grinding to fairly fine particle 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 ...

Rock Crushing methods and How to recover gold from Ores

So as you are crushing, stop and screen your material, removing any free gold which has already separated from the rock during your crushing that won't go through your screen with your fingers. The coarser rock that won't go through your screen can then be returned to the crusher for further work to break it down, and the fines won't get in the way.

What is the Alluvial Gold Mining Method?

The content of alluvial gold in the ore is very low, so in order to extract the gold from the ore, the ore needs to be crushed and ground first, and then the the gold is pre-enriched or separated from the ore by the beneficiation method. Generally, the alluvial gold mining concentrator mostly uses jaw crusher for coarse crushing and cone crusher for medium crushing.
