As one of the rarest and most precious metals, gold is used as an international reserve, value preservation, and hedging. Gold has been mined by humans for hundreds of years for various purposes including decoration and industry. Gold, like other minerals, is a non-renewable mineral resource. So how to mine and sort gold has become the main research course in the gold mining and sorting industry. There are currently many types of gold sorting equipment on the market in our country. Which one to choose? This kind of gold selection equipment has always been a problem that troubles our customers. In response to this problem, Henan Bosite Machinery Manufacturing Co., Ltd. hereby briefly introduces the gold selection equipment, hoping to be helpful to our customers and friends.
There are many methods of beneficiation in gold mines, which is also the main problem that leads to the wide variety of gold beneficiation equipment. The main beneficiation methods of gold mines are gravity separation, flotation, and chemical beneficiation. There are also cases where a variety of gold beneficiation methods and equipment are combined. Here are a brief introduction to each.
The gravity separation method has the longest application time in the gold separation industry, the most mature technology, and is also the most commonly used gold separation method. This gold separation method has the advantages of energy saving, high efficiency, environmental protection, etc., especially in placer gold ore dressing. The application is even more common, and gravity separation is used in almost all placer gold ore roughing. For rock gold ores with coarse and medium grains, the gravity separation method can often obtain ideal beneficiation indicators. However, for rock gold ores with fine grains and above, gravity separation is still a difficult problem. It is also agreed internationally. The continuously developed centrifugal concentrator, centrifugal separator and a series of fine particle gravity separation equipment are said to have achieved great success.
The main equipment for gold separation by gravity separation method include: jig, shaker, spiral chute, centrifugal concentrator, etc.
Flotation is a new gold separation method that has emerged in recent years. It is separated based on the difference in flotability between useful minerals and waste rock. It has a significant beneficiation effect on gold sulfide and other rock gold minerals, and on oxidized gold, etc. The beneficiation effect of refractory gold ore is poor. Flotation is a mineral processing method that is widely used in the gold processing industry. However, due to its high degree of environmental pollution, large investment in mineral processing equipment, and high operating costs, small and medium-sized gold processing plants are unable to choose flotation as the gold processing method. method.
The flotation gold separation equipment mainly includes: crusher, ball mill, classifier, mixing barrel, flotation machine, etc.
In the field of gold beneficiation, chemical beneficiation mainly refers to cyanide gold extraction. This gold extraction method is the most effective and thorough gold extraction method. All-mud cyanidation even reduces the cyanide gold extraction method to A peak. However, cyanide is highly toxic. Today, with increasingly high environmental protection requirements, small cyanide gold extraction plants are explicitly prohibited by the state. Only large gold processing plants with their own pollution control equipment can use cyanide to extract gold. In addition, the equipment for gold extraction by cyanide method is expensive and the operating cost is too high. Medium and small mineral processing plants generally do not use this method.
To sum up, among the gold selection equipment, only the gravity selection method has the smallest investment, the strongest applicability, and the most ideal gold selection equipment method. The gravity selection equipment is also the most ideal gold selection equipment.
