Barite is a non-metallic mineral with barium sulfate as its main component, is often associated with galena, sphalerite, chalcopyrite, cinnabar, etc. It has the advantages of high density, good filling property, insoluble in water and acid, non-toxic, absorbing radiation, stable chemical and thermodynamic properties. For the barite powder processing, Guilin Hongcheng has rich experience in barite powder making machine, focusing on the development and manufacture of high-capacity and high-efficiency grinding, help barite powder to improve efficiency, reduce energy consumption, deeply trust and praise by the enterprise.

1. A brief introduction to barite.

Pure barite is white and glossy. Due to the influence of impurities and mixtures, it often appears gray, light red, light yellow and so on. Barite with good crystallization can also be transparent crystal. Barite is a sulphate mineral. BaSO4 is the most widely distributed barium bearing mineral in nature.

2. The development of barite.

In the history of human development, barite has played a tremendous role and value. After several centuries of excavation and research, barite cocoon breaking into a butterfly has become an important non-mineral in industrial construction.

As early as 1602, a shoemaker named Cassio Lauro accidentally roasted barite containing barium sulfate with combustible materials, and saw a ray of light in the dark. Later people called the stone Pololite.

In the seventeenth century, Swedish chemist Scheler further studied the borneolite and heated the new soil to obtain pure soil (oxide).

In the eighteenth century, British chemist David used mercury as the cathode, platinum as the anode, electrolytic barite (BaSO4) to produce barium amalgam, after distillation of mercury, it was obtained a low purity metal, barys (renamed) in Greek, will be called barium, the element symbol is determined as Ba.

Nowadays, people have discovered a lot of barite value; barite has become a good non-metallic mineral for the benefit of mankind.

3. Barite reserves

China is rich in natural resources and has found 24 provinces in China to contain barite resources. There are 230 barite mines in the country. The resources reserves are 3.1 trillion tons, the basic reserves are 35.8562 million tons, the reserves are 13.335 million tons and the resources are 27.0884 million tons.  Guangxi Province is a big province with abundant barite resources in China. The production of barite reaches 1.73 million tons, of which 1.1 million tons are exported. In addition, Tianzhu in Guizhou, Xinhuang in Hunan, Liulin in Suizhou City, Hubei Province are rich in barite resources.

4. Classification of barite

According to mineral composition, barite is rich in classification and can be classified into the following categories:

1. Single mineral barite ore

The BaSO4 content of such barite ore is 80-98%, and there are very few associated minerals.

2. Fluorite barite ore

Barite and fluorite are the main minerals of this kind of minerals; other associated minerals are quartz and calcite.

3. Sulfide ore barite ore

It is mainly composed of barite and iron sulfide, copper sulfide, zinc sulfide and lead sulfide. Its associated minerals are quartz, calcite and fluorite.

4. Quartz barite ore

It is mainly composed of barite and quartz, and the content of quartz is up to 30-45%. Generally speaking, the disseminated grain size of quartz will affect the quality of ore. The finer the disseminated grain size, the more difficult the separation.

5. Clay or sandy barite ore

Such ores contain different amounts of clay, rock fragments, mono mineral barite fragments, etc.

6. Iron ore barite ore

It is mainly composed of barite ore and iron ore (magnetite, hematite, goethite, etc.). Other associated minerals include quartz and calcite.

5. Barite usage

Nowadays, with the rapid development of economy, the demand of barite market keeps rising, which is widely used in more than ten industries, such as chemical industry, electronics, building materials, metallurgy, textile, and medicine and so on.

A. Petroleum drilling: Barite can be used as a weighting agent for oil and gas drilling mud. It has the functions of cooling bit, reinforcing borehole wall, controlling crude oil and natural gas pressure, so as to stabilize oil and gas production and prevent blowout accidents.

B. Chemical field: Barite is the raw material of barium chemical industry (5%-10%), producing basic barium salts (barium sulfate, barium chloride, barium carbonate), and then producing various barium compounds such as zinc barium white, barium hydroxide, barium oxide. Other uses include filler and mineralizer for cement (< 5%).

C. Glass manufacturing: mainly used as deoxidizer, clarifier, cosolvent, can increase the optical stability, luster and strength of glass;

D. Rubber, plastic and paint: it can be used as seasoning, brightening agent and weighting agent.

E. Architectural field: Barite can be used as concrete aggregate, paving materials, etc., can replace lead plate used in nuclear facilities, atomic energy plants, X-ray laboratory shielding, prolong the service life of the road.

6. Recommended equipment for barite grinding mill.

For barite powder preparation, mill selection is very important. As a powder equipment manufacturer, Guilin Hongcheng specially manufactures Raymond mill, vertical mill, ultra-fine mill, ultra-fine vertical mill and other equipment for the barite powder market to meet the needs of different industries for the preparation of barite powder. Hongcheng barite grinding powder mechanism has high efficiency, low noise and low energy consumption, stable performance, stable running, energy saving and reduce of consumption, easy maintenance, it is the best for barite powder making.
