Gold Extraction Process in Forui

Gongyi Forui machinery factory is a professional processing equipment manufacturer and we have rich experience on the separation of metal smelting slag such as silicon manganese slag, ferrochrome slag, nickel iron slag, copper slag, lead slag, etc. We will introduce the gold process in Forui.

The embedded granularity size of the gold in ore determines the milling and the beneficiation method. During the milling processing, when coarse gold and the other composition liberates, recovering by gravity separation or amalgamation will do a favor to the following floatation separation and the cyaniding because the coarse gold is very hard to be floated, or needs long time to cyanide.

For recovering of the coarse gold, gravity separation is a best way to get most of the gold. Then amalgamation or cyaniding will be considered according to the gold ore nature to recover gold or other metals.

The flow sheet for the coarse gold recovery covers: screening--jigging--amalgamation or screening--jigging--shaking table.

For the recovery of coarse gold in lodegold ore, gravity separation is usually adopted after rod mill to mill gold ore to separate gold & gangue, and then the mixture will be put into the jigger to recover the coarse gold. Sometimes multi-milling & multi-separation will be involved to recover coarse gold as soon as possible avoiding gold loss after the milling.

And for the lodegold, the gold beneficiation flow sheet can be: crushing--rod milling--jigging--amalgamation.

Gravity separator-jig machine is a good gold extraction machine for gold extraction. Forui jig machine have been used to beneficiate alluvial gold in Mongolia, Zimbabwe, Congo and many provinces in China. Jig machine of JT series, LTA series and trapezoidal 2LTC6109/8T is mainly used as alluvial gold extraction machine or tin extraction equipment. (PS: Trapezoidal 2LTC6109/8T jig machine have begun to work to recover tin from tin sand in Russian since Oct. 2012. )

Free gold extraction test can be carried out for customers for free in Forui and according to the test we design process and equipment configuration for our customers. And your further contact is highly appreciated.
