What is barium sulfate? Barium sulfate,as X-ray double contrast agent.The high density gastrointestinal contrast agent can be made into different proportional suspensions, but it is usually used with low density gas to achieve double contrast. Commonly used in digestive tract radiography, according to domestic users reported that the thickness of barium sulfate, better than fine and uniform barium sulfate. For intestinal fistula formation and prone to perforation of certain intestinal diseases, such as appendicitis, diverticulum, ulcerative enteritis, parasitic infections. Barium sulfate be used as filler in the industrial production of plastic. Barium sulfate unique excellent performance, so that it is widely used in plastic products and as one of the new functional modification materials. Barium sulfate has the characteristics of improving the chemical corrosion resistance, heat tolerance and product appearance of the plastic products. Barium sulfate can be used for pp. Abs. Pa. Pet and other resin production of home appliances shell, mechanical parts, automotive parts, air-conditioning panels, electric kettle shell and so on. Barium sulfate can also increase the proportion of plastic products, improve the wear resistance of plastics, anti-aging, improve the luminous effect, and expand the application of plastic products. The characteristics of barium sulfate in plastics The natural ore (barite) is made of barite powder (also called heavy barium sulfate) after crushing, washing and drying, and is white or gray powder, with a density of 4.3~4.6g/cm3. Barite heated to 1100 Shan reduction to produce soluble barium sulfide, and then the role of sulfuric acid or sodium sulfate precipitated barium sulfate (also known as light barium sulfate), fine particle size, whiteness can up to 92 degrees above. Barium sulfate has many characteristics with large proportion, good luster, good thermal stability and excellent processing performance and so on.
Before the "One Belt And One Road" forum be held, Habao Shan, the representative of Kazakhstan Hall Fruit-Oriental Door Special Economic Zone (hereinafter as "Huo Dong Zone") in China, also organized the related investment promotion meeting with "One Belt And One Road ", and held in April of this year Nanjing. Although the meeting’s scale will be small, it is the result of Baoshan’s hard work in the past one year, the aim of meeting is to promote the Huo Dong Zone to the Chinese enterprises, who plays an important role in the "One Belt And One Road ", There are many Chinese enterprises and the Zone management company signed investment cooperation Memorandum.
Through the efforts of Habao and his colleagues, many Chinese enterprises are becoming familiar with the new Zone. At present, there are about 10 Chinese companies expressing their intentions to invest in Huo Dong Zone, These companies are from Jiangsu, Guangdong, Shaanxi and other areas respectively, planning in the Huo Dong Zone construction of beef and mutton and fur processing, dairy, warehousing refrigeration, barite and lime mining and other factories.
According to Habao Shan, after the prophase construction, Huo Dong Zone's road, hydropower and other infrastructure have been put into use in August 2016, and has the conditions of settled. Currently, Haguo has sixty or seventy companies registered in Huo Dong Zone, one of the companies started to build factories.
Collector is the key to determine whether barite minerals can be effectively separated. Commonly used collectors can be divided into three kinds according to the adsorption form:
① Chemically adsorption anionic collector.
② Physical adsorption cationic collector.
③ Amphoteric collector between these two collectors.
And it can be divided into two kinds according to separation process of barite and fluorite: one kind is inhibiting barite flotation fluorite, the other kind is inhibiting fluorite flotation barite.
Our engineers used sodium oleate as fluorite collector, YZ-4 tannin extract and water glass, aluminum sulfate combination as inhibitor, to inhibit barite flotation fluorite. Finally we got fluorite concentrate with a CaF2 grade of 96.81% and a recovery rate of 92.44% and a barite concentrate with a BaSO4 grade of 91.36% and a recovery rate of 86.75% . The separation of fluorite and barite was achieved well. One of our engineers used sodium dodecyl sulfate as collector, sodium silicate and citric acid as fluorite inhibitor, used a program of inhibition of fluorite and flotation barite, got barite concentrate with BaSO4 grade of 93.28% and a recovery rate of 94.06%.

After the last on-site reconnaissance, today main job of HOTer is to survey and draw
Surveying and drawing is to make preparation for the Mine construction, mining production, industrial square construction which are about to get started
The main work of Surveying and mapping: mine construction survey, sorts of surveying work for the construction of mine engineering survey that in mine construction and mining process, that is building projects survey on the ground, the underground control survey and construction survey, shaft orientation survey and shaft induction height survey, holing through survey.
Mine surveying is an important part of mine construction and production process. As the mine survey work involves the ground and underground, it will not only serve for mine production construction, but also provide information for production safety. By doing this, the project investors (owners) and mining contractor (hot) can make a decision for production safety.
