Gold Beneficiation Overview

According the structure of mineral status of gold, the gold mineral can be divided into three categories, the gold mineral gold deposits, gold-bearing minerals and gold minerals contained. The so-called independent gold mineral, refers to gold and gold-bearing minerals in the form of the mineral output of gold, it is the nature of the most important occurrence in the form of gold, the main target of industrial development and utilization.

The current mainstream technology for gold beneficiation, usually by crushing by crusher, then grinding by ball mill, and get the concentrate or tailing by gravity concentrate plant or flotation concentrate plant, finally through chemical method and smelting to get the product gold.

The first part is crushing and grinding, most use jaw crusher to crushing the raw ore, or use cone crusher to get small size ore, most of small or middle plant will choose 2 crushing parts rule as more crusher less grinding to get fine particle size. The second part is gravity concentrate plant, the gravity beneficiation concentrate according different density of different minerals, it’s the main important method for gold recovery. Most equipment as sluice, shaking table, jig separator and centrifugal concentrator etc. The third part is flotation concentrate plant. In China there is more than 80% gold beneficiation plant choose the flotation machine to recover gold. The product after flotation will deliver to smelting factory process. Except those method, also have mixing mercury, cyanide, leaching and melting. Our factory is professional in gravity concentrate plant, the gravity concentrate plant with less cost, high capacity, easy operation features. Our equipment is used on many gold mine areas in the world, we can supply different gravity equipment, like as gold shaking table, sluice box, gold centrifugal concentrator, jig separator etc.
