At present, the most commonly used gold processing method is the gold cyaniding process. More than 80% of the gold mines use gold cyaniding process to extract the gold. Therefore, what are the methods for the gold cyaniding process? What's the difference among these methods? Generally, the gold cyaniding processes mainly include carbon in pulp (CIP), carbon in leaching (CIL), pool leaching process and heap leaching process.

There are a variety of iron ores in nature, mainly including magnetite, haematite, limonite, siderite, so the beneficiation of iron ore needs the suitable process to improve the economic benefit. The beneficiation of iron ore needs a series of process, including crushing, grinding, magnetic separation, flotation, gravity separation.

Magnetic separation method is a common mineral processing method of separation. Magnetic separation method is to achieve the separation in the non-uniform magnetic field of the magnetic separators according to the magnetic differences among various minerals.

There are three common gold processing methods widely used in many gold processing plants according to the different types of gold ore characteristics and user requirements, includes gold cyaniding process, gold flotation process, gold gravity separation process.

Froth flotation process is a kind of mineral processing technology that uses the flotation reagents to separate the ore according to the physical and chemical properties of the surface of the ore. What are the common froth flotation processes? Do you know the application condition of froth flotation process?

The gold in this kind of ore is often physically wrapped or incorporated into the various chemical compounds, so it cannot contact with the cyanide solution and is difficult to be leached. Therefore, what are the reasons for the low cyanide leaching rate of gold ore? And what should we do to solve this problem?

Compared with the flotation of sulfide minerals, the flotation of non-sulfide minerals is more difficult. The non-sulfide minerals usually have a higher water solubility, and the useful minerals and gangue minerals are usually similar types, with a small difference in surface properties. So, what should be noticed in the flotation separation of non-sulfide minerals?

Cyanidation has a history of more than 200 years since it was applied to gold and silver ore extraction in 1887. At present, cyanidation is still one of the main gold extraction processes due to its high recovery rate, high adaptability to ore and local production.

According to the working principle of the magnetic separation process, we can know that the magnetic separation process mainly uses the magnetic differences among various minerals to realize mineral separation in the uneven magnetic field of various magnetic separation equipment. Thus, we can find two key factors that affect the magnetic separation process: one is the magnetic difference of minerals, another is the magnetic field distribution of magnetic separation equipment.

There are many factors affecting the flotation process, including non-adjustable factors and adjustable factors. Among them, non-adjustable factors refer to the ore property, adjustable factors mainly include grinding fineness, pulp concentration, pulp pH value, reagent system, pulp temperature, water quality, flotation time and so on.

According to the principle of gravity separation, the form of medium movement and the purpose of operation, the common gravity separation methods mainly include jigging separation, shaking table separation, chute separation, dense media separation and hydraulic/wind power classification.

Fluorite mineral is one of the common non-metal minerals, which is also called CaF2. In thesis, we will sketch the processing technology of separating fluorite mineral with calcite, barite, quartz, and sulfide minerals.
