Abstract The authors investigate a new reagent—modified water-soluble polymer of polyvinyl caprolactam (PVCL)—as a collector in flotation of gold-bearing sulfide ore. Modified PVCL is obtained by solid-phase modification of poly(N-vinyl caprolactam) by thiourea. The electron scan and laser microscopy identified adsorption of PVCL at gold grains applied …

01 Gold ore flotation process and equipment. Gold ore flotation process is a common method for extracting gold. It is based on the principle of selectively attaching air bubbles to hydrophobic particles (gold) and separating them from hydrophilic particles (surrounding rock minerals). The process includes the following steps:
Flotation Reagents: Properly selected flotation reagents are crucial for altering mineral surface properties and increasing the selectivity of gold. pH Level: The acidity or alkalinity of the solution affects mineral flotation. Flotation …
The liquid level in the single flotation tank of the flotation machine is too high. If the flotation machine has a problem with high liquid levels in a single flotation tank, the reason is mostly that the suction pipe is blocked. Solution At this time, the operator needs to stop the machine to clean the suction pipe.

When using flotation beneficiation method to treat ore with high mud content in raw ore, if the crusher is blocked, the recovery rate of gold ore decreases, and the flotation index becomes worse, it can be considered whether it is caused by the high mud content of raw ore. Flotation method is a relatively complex gold beneficiation method.

The simplest method of treating a carbonaceous ore is the method described by R. W. Nice (1971) at the McIntyre Porcupine Mine where the carbon, which contains very little gold, is floated off and discarded. The remaining ore is then responsive to cyanidation. This does not work at Carlin because the carbonaceous compounds have a high gold content.
