Gold Concentrator Machine Price

Gold beneficiation and concentration operations include cyanidation, base-metal flotation, gravity concentration, and amalgamation. It aims to recovery the gold concentrate to achieve economic value.

Zenith is a global manufacturer and supplier of concentration and beneficiation plants. We developed complete range of gold concentrator machine including crushing plant, screening machine, ultrafine mill; magnetic separator, floatation equipment, classifier, gravity separation equipment; and some auxiliary equipment. We provide gold concentrator machine in Kenya, Ghana, India, South Africa, Nigeria, Zambia, Zimbabwe etc. If you want to know gold concentrator machine price, or any other information, please contact us.

Gold Concentration Method

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world.

However, froth flotation processes may also be used to concentrate the gold. In some cases, particularly when the gold is present in the ore as discrete coarse particles, a gravity concentrate can be directly smelted to form gold bars.

In other cases, particularly when the gold is present in the ore as fine particles or is not sufficiently liberated from the host rock, the concentrates are treated with cyanide salts, a process known as cyanidation leaching, followed by recovery from the leach solution.

Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values. Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by roasting or wet pressure oxidation.

Sometimes gold is present as a minor constituent in a base metal concentrate, and is recovered as a by-product during production of the base metal. For example, it can be recovered in the anode slime during the electrorefining process.
