Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.

In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores

Refractory gold ore pretreatment Treatment of refractory gold ore (whole ore and flotation concentrates) has become more prominent since the 1980s, with many gold discoveries often including ores that are wholly or partially refractory. Refractory pre-treatment processes include pressure oxidation, biological oxidation and various forms of roasting.

The tailing from the lead flotation circuit is the feed to the zinc circuit. The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors. Conclusion. Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation.

The flotation process can maximum concentrate the gold into sulfide mineral concentrate, so as to abandon the tailings early and reduce the ore dressing cost. In addition, the flotation process often used to deal with the multi-metal ore, realizing efficient and comprehensive utilization of mineral resources.

Flotation is widely used to concentrate copper, lead, zinc, iron and even gold and silver minerals, which commonly accompany one another in their ores. Many complex ores formerly of little value have become major sources of certain metals by means of the flotation process.

Gold Ore Processing: Project Development and Operations, Second Edition, brings together all the technical aspects relevant to modern gold ore processing, offering a practical perspective that is vital to the successful and responsible development, operation, and closure of any gold ore processing operation.

Xinhai has been committed to the research and development of gold ore dressing technology and equipment for 20 years and possessed rich project experience, who can provide you with reliable equipment and technical services.

The practice of gold minerals beneficiation is optimized by using the information obtained from applied mineralogy. In this way, at the moment of development and select a process for treatment a gold ore, try to identify the gold minerals is the first step. Obviously, the detection of non-valuable minerals is important.

Mineral processing: Mineral processing, ... the use of spirals has increased rapidly. They are especially effective at concentrating heavy mineral sands and gold ores.

Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest.

Gold mineral flotation normally adopts one stage grinding-flotation process, but stages grinding and flotation for ore with uneven distribution. Grinding fineness of gold For the gold wrapped in sulfide minerals, sulfide ore reaches monomer dissociation; but for the gold with gangue, grinding fineness should reach gold monomer dissociation.

Additionally, copper and gold ore samples were obtained from crusher discharges of active mineral processing plants and used in the sorting tests as received after screening. Samples except quartz were additionally screened to narrow size fractions in order to investigate the effect of particle size on sorting performance.
