Main Methods of Gold Ore Processing

1. Flotation Separation Processing: The flotation process is the most common gold ore beneficiation process. It is often used to process highly floatable gold-bearing sulfide minerals. The flotation process can maximize the enrichment of gold in sulfide minerals, and the tailings can be directly discarded, and the beneficiation cost is low.

2. Gravity Separation Processing: In addition to the flotation process, the gold ore gravity separation process is also mostly used in gold ore dressing plants. For gold mines where the gold is unevenly distributed in coarse and fine grains, a gravity separation device is usually installed in the pre-flotation grinding and classification circuit to recover the particulate gold in advance.

3. Gold Carbon-in-leach(CIL) Processing: The gold CIL process is suitable for beneficiation of high-grade large-scale gold mines and gold mines with high associated silver and copper content. For small gold mines, it is recommended to use fine gold ore flotation process.

Flotation Separation Process

The flotation of gold minerals generally adopts a one-stage grinding-flotation process, and a staged grinding-flotation process can be adopted for ores with uneven particle size. For gold mines with complex ore properties, the flotation process is also more complicated. Flotation equipment is mainly a flotation machine. XJK flotation machine is a traditional self-suction flotation machine, JJF, SF and BF flotation machine are a new self-suction flotation machine.

The principle of gold flotation is: flotation of large-density and coarse-grained minerals often use thicker slurry; on the contrary, when flotation of small density, fine-grained and sludge, use a thinner slurry, which can ensure a higher recovery rate and improve the quality of the concentrate.
