Beneficiation. In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product ( ore concentrate) and a waste stream ( tailings ). There are many different types of beneficiation, with each step

The process of gold ore processing and production mainly includes three processes: crushing, grinding and beneficiation. In the crushing process, the three-stage closed-circuit crushing is more modern and suitable for high-hardness gold ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency;

Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes. The choice among these processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained attention because of low cost and environmentally friendly operations. In this study, gold pre

In summary, the four beneficiation processes can better recover gold from high-sulfide gold ores. When considering the gold concentrate grade and gold recovery rate, the mixed gold flotation process and the flotation-roasting-cyanidation leaching process show ideal index for gold processing.
