Gravity separation is one of the main means of rock gold ore beneficiation, especially suitable for processing coarse-grained and high-grade rock gold ore. In the beneficiation process, grinding particle size, as a key factor in the gravity separation process, directly determines the dissociation and gravity separation efficiency of minerals. So in the gravity separation process, what are the requirements of different gravity separation methods for particle size? In this article, we will analyze and answer from multiple angles!Details>>
Recently, the price of gold has fallen sharply, but it has no impact on gold mine development. As easily exploitable rich ore resources gradually decrease, poor ores, fine-grained embedded ores, and complex multi-metallic paragenesis ores have become the main development force. For this type of gold mine, flotation gold extraction is often used to achieve recovery.Details>>
Flotation is one of the commonly used ore dressing technologies in gold ore dressing plants. It is suitable for the dressing of various complex gold ores, especially in the treatment of difficult-to-select gold ores such as fine-grained intercalation and polymetallic paragenesis. In the flotation process, reagents are the key. The hydrophobicity and hydrophilicity of the mineral surface are changed by adding reagents to separate them. Among them, frothers, as the key medium for constructing the gas-liquid interface, directly affect the generation and stability of bubbles and the fluidity of the foam layer, and then determine the core indicators such as gold recovery rate and concentrate grade. This article will introduce the commonly used frothers in gold mines.Details>>
Gold exists in various forms in nature, and its occurrence form determines the choice of refining process. Natural gold, also known as free gold, exists in the ore in the form of a single substance, with different particle sizes, and is a relatively easy-to-extract gold form; associated gold usually coexists with sulfide ores (such as pyrite and chalcopyrite), and the separation and recovery of the main metal and gold must be taken into account during the refining process; fine-grained gold is tightly wrapped by gangue minerals or sulfides, and the particle size is often less than 10μm. It is a difficult-to-process ore, which is difficult to extract and requires special processes.Details>>
Oxidized gold ore is a specific type of oxidized ore, in which the gold element mainly exists in the ore in an oxidized state. In oxidized gold ore, in addition to gold oxidized minerals, it may also contain oxidized minerals of other metals and some gangue minerals. As an important type of gold resource, oxidized gold ore accounts for about 30%-40% of the global gold reserves. Effective development is of strategic significance to alleviating the contradiction between gold supply and demand. This article will focus on the characteristics of oxidized gold ore, the difficulties in refining gold, and the technology of refining gold from oxidized gold ore.Details>>
In the field of gold resource development, carbon slurry gold extraction technology is widely used because of its simple operation and strong adaptability.

Zinc powder replacement gold extraction is a common method for gold extraction. It mainly uses zinc powder in a solution containing cyanide gold complex to replace gold ions with its reducing property, thereby realizing gold extraction. Zinc powder replacement gold extraction has high efficiency and relatively low requirements for equipment. It can effectively obtain high-purity gold from cyanide leaching solution. In the process of zinc powder replacement gold extraction, the use of equipment is very important and is also the key to its gold extraction efficiency. This article will introduce to you what are the main equipment used in zinc powder replacement operations?Details>>
CIL carbon leaching gold technology is a cyanidation technology widely used in the gold extraction process. The method is to dissolve the gold in the ore in a cyanide solution and use activated carbon to adsorb the dissolved gold at the same time, so as to achieve efficient recovery of gold. CIL carbon leaching gold combines the two steps of leaching and adsorption, and the two processes are carried out simultaneously by adding activated carbon to the slurry containing gold ore. Let's take a look at what aspects of the carbon leaching gold technology process are included.Details>>
The carbon-in-liquid leaching process is one of the commonly used methods for gold ore beneficiation. This process is further developed on the basis of the carbon-in-liquid slurry gold extraction process. It combines the two key steps of cyanide leaching and activated carbon adsorption into one, effectively improving the gold selection efficiency and economic benefits.Details>>
