A variable in the flotation circuit design is to include column cells in the cleaner circuit in order to improve the gold concentrate quality and to reject insoluble material. Column cells are particularly important when the ore present high content of silicates, carbonates and clays, which affect thickening, filtration and concentrate grade.

In gold concentration, the commonly used gravity separation methods are gold jig separation, gold shaking table separation, and gold chute separation. Jigging gold The main equipment for jigging is the jig separator. The process of jigging is to mix mineral particles with different specific gravity and layer them according to specific gravity ...

As a result, these particles become buoyant and rise to the surface of the flotation cell, where they can be collected and further processed to extract gold. The main advantage of using this method is that it can efficiently recover gold from low-grade or refractory ores, which are challenging to process using traditional methods. Additionally ...
