For the phosphate processing, one phosphate processing method is positive flotation. Another phosphate processing method is to float an impurity mineral and sink a phosphate mineral, called reverse flotation.

Now, the development of gold extraction technology has been relatively mature and complete. Generally speaking, gold extraction processes are mainly gold flotation and gold cyanidation.

Because of the different deposits and ore characteristics, the feldspar mining processes are quite different with each other. Common feldspar mining processes include hand sorting, desliming, magnetic separation, gravity separation, flotation and combined processing technology, in order to separate quartz, iron, mica and other minerals.

Flotation separation method is a relatively complicated method of mineral processing. When using gold flotation method to separate gold ores, the range of parameters determined by the beneficiation test and the production needs of the beneficiation plant are adjusted to determine specific mineral processing schemes for different gold ores to achieve ideal recovery and gold concentrate grade.

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.
