The preparation method of barite weighting agent for bentonite drilling mud
The preparation method belongs to the LPG(petroleum and natural gas)drilling with high weighting use characteristic of preparation process. The aim is to improve its aggravating properties by reducing the inhibition of barite. The surface modification of the barite was carried out by treating the barite in turn with ethylenediamine tetraacetic acid disodium salt and aluminum lignosulfonate. The amount of ethylenediaminetetraacetic acid disodium salt is from 0.025 to 0.150% and the amount of the lignin sulfonate is 0.18 to 0.20% of the barite content. When these two agents are co-treated, a composite hydrophobic layer is formed on the surface of the barite to change the surface electrical properties of the weighting agent, resulting in alienation of the particles, thereby preventing the drilling mud structure from solidifying and significantly reducing the barite Thickening. This ensures that a large amount of weighting agent is added to the drilling mud at the required level while maintaining structural first-class denaturation. The lignin sulfonate is prepared in the following manner: 250 g of sulfuric acid and dyestuff containing 40% dry material was mixed with 75 ml of an aqueous solution of aluminum sulfonate (containing 20 g of sulphonic acid). The mixture was allowed to stand for 2 hours, filtered, and the filtrate was poured into calcium sulfate slag. The pH of the filtrate was 0.95-7.10 by adding sodium hydroxide, the specific gravity of the prepared lignin sulfonate solution was 1.13-1.15 g / cm3, Is 23-45 mPa / s. The resulting solution is evaporated to dryness by steam, and the resulting powdery product is prepared and can be used as a modifier for barite.
Barium sulfate as filler in plastics

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.

Analysis of barite recourse in China & future market
  The barite in the world is abundant with over 2 billion tons, mainly in America, Russia, China, Peru, India, and so on. China owns the rich barite recourse in the 26 provinces, especially in the southern. The reserve in Guizhou occupies 1/3 of China, while Hunan and Guangxi ranks the second and third. The barite in China is not only accountable but also premium. The BaSO4 is more than 92.8%, and the rich reserves occupy 99.4% in the whole country. Until 1995, 460 million reserves were discovered. China supplies 25-30 million tons barite annually, all exploited in domestically. China consumes 12-13 million tons barite annually. 7-8 million tons are used for oil and gas exploitation, 60% of the total consumption. 4-6 million tons are used for the Ba chemical products, 30% of the total. 1 million tons are used for other fields, 10% of the total. China is the biggest country to export the barite. In 1990s, China exported 15-20 million tons barite to the outside the world. In 1996, China export 2.058 million tons barite and Ba salt, with 1.86 barite and 0.198 Ba chemical products, mainly to America, Holland, Japan, and South Korea. China seldom imports the barite, only a small amount of Ba chemical products. In the future years, the demands will be increasing with a bright market. In the industry of supply is less than demand, much profits can be seen.
Optimized measurement method of barium sulfate content in barite ores
  Barite is widely used in industry. Generally, we measures the content of barium sulfate to indicate its purity, but it is usually associated with strontium, lead, silver’s sulfate.Traditional Barite analysis method, because of its difficult separation, easily to make the results of high measurement. The following is the optimized method of barium sulfate measurement 1. Impurity removal process of soluble sulfate, barium carbonate and sulfide Weighing 0.5g samples in 50mL high-type beaker, adding 1+1 10mL of hydrochloric acid solution,after micro-boiling 30min in the cryogenic furnace, then add 10% nitrate solution 10mL keeping micro-boiling 20min,slow quantitative filter, collecting precipitation after slightly cold. 2.Decomposition of sample process by sodium carbonate, zinc oxide semi-melt method The precipitation and filter paper are transferred together to the 30mL porcelain crucible, after the low temperature fully ashing in the Muffle furnace, increases the temperature to 700 ℃, and then add 5g of sodium carbonate, zinc oxide (3+2) mixture solvents, mix evenly, and covering 2g of mixture solvents above them, put into the muffle furnace, start from low temperature and gradually increased temperature to 800 ℃, keep burning 1hour. 3. leaching process of sulfuric acid roots in semi-melt Removing the crucible out and slightly colder, put in the 250mL beaker, add 100mL hot water to leach, use hot 20% sodium carbonate solution wash out the crucible, keeping hot with slow filter paper in 500 mL beaker, and then use the heat sodium carbonate solution 20g/l wash precipitation 6-8 times. The precipitation of the funnel is transferred together with the filter paper to the original beaker. 4. Precipitation and measurement of sulfuric acid roots Using 50% hydrochloric acid solution neutralize to red and in excess of 3mL, regulating the volume of the filtrate to 300mL by water,boiling to remove carbon dioxide, adding 100g/L barium chloride solution 25 ml, evenly stirring after 1min and keeping boil for a few minutes, and heat preservation for half an hour, then static overnight. After slow-rate precipitation filtration by quantitative filter paper,moving it into the 30mL porcelain crucible with the prior burning to the constant.weight after low temperature ash in 800 ℃ burn to the constant weight and weigh. Total content are sulfur in barium sulfate, strontium sulfate, lead sulfate and silver sulfate. 5. Removal process of interference from strontium, Pb and Ag’s sulfate Adding the 50mL (1+1) hydrochloric acid solution to the collected precipitation during the leaching process of the semi-melt. Put it on the low temperature electric furnace,after the micro-boiling,dissolution and precipitation , the filtrate is transferred to the 250mL volumetric flask, and the content of Sr, Pb and Ag in the solution is measured by ICP-OES and converted to in the form of Sr, Pb and Ag’s sulphate. The total content of sulfur in the previous link deducted that measured in this section, the result is the sulfur content of barium sulfate in barite,then convert into barium sulfate. By optimizing the treatment of each condition in the process, this method is better than the traditional semi-melting method, less disturbance than the whole melting method, aim at higher requirements measurement of barium sulfate in barite ores,it could achieve a better effect.(P.S,only available the content of barium sulfate between 15-90% to assure accuracy.)
The preparation method of hydrophilic drilling mud barite aggravating agent
This system is part of the LPG mining industry and suitable for the preparation of aggravating drilling mud,in order to increase the aggravating performance of the agitator at the temperature of 150 °. For this reason, water glass is added in the amount of 0.08 to 2.00, equivalent to 0.01 to 0.10% by weight of the barite concentrate, before mixing the barite flotation concentrate into the aqueous solution of tripolyphosphate. In order to strengthen the preparation process in the stirring and simultaneous vibration conditions for barite flotation concentrate treatment, this method can guarantee the different nature of the particles of the activation of hydrophilicity. A water glass was added to the aqueous solution of tripolyphosphate to achieve the whole particles to obtain  hydrophilic surface, while the free state of sodium tripolyphosphate was not found in the preparation of the aggravating agent. This may be due to the fact that the water glass is chemically adsorbed on the surface of the layered silicate and quartz particles, and if it is hydrophilic, sodium tripolyphosphate is reversibly adsorbed on the particles to ensure the barite’s chemical adsorption of particles. For example, take 1099 gram barite flotation concentrate with the density of 4.10 g / cm3 and the water content of 9.0% , stirring with 24.59 g aqueous solution containing 2 g of sodium tripolyphosphate and 0.2 g of water glass for 5 minutes. The above amount of the solution ensures the process requirements of the barite aggravating agent prior to drying (11%). In order to uniformly add the hydrophilic layer of the agent to the surface of the whole particle activation, the mixing of the components is required to be match up vibration to carry out. For this purpose, a mixer with two blade-like shafts (0.25 m / sec) and a vibration parameter with an eccentric vibratory linkage (amplitude of 30 Hz at an amplitude of 2.0 mm at the vertical plane) can be used. After treatment, the sample was dried at a temperature of 500 ° C for 3 minutes in a muffin donkey,reach the residual moisture of not more than 2%. The content of free sodium tripolyphosphate was analyzed from the prepared samples, and the hydrophilicity and aggravating performance were measured. The necessary hydrophilicity of the surface had been guaranteed by the best ratio of mixed barite aggravating agent (the hydrophilic index is not less than 80%) and the free trimerization is not present in the product.At the some time,aggravating agent increases the aggravating performance.

How to prepare ray shielding materials by barite
Barite is widely used and one of the most important is for the preparation of ray shielding materials.The main component of barite is barium sulfate which can effectively shield the ray.Today we introduce how to prepare ray shielding materials by barite. The safety of nuclear radiation has been the key to further development. Since the birth of nuclear technology,it has been rapid development.In the fields of nuclear power, military, education, scientific research,medical and others have been widely used, however the security problem is always an inevitable problem. Ordinary shielding materials, such as cement-based shielding material characteristics with cheap price,wide range of raw materials, easy construction and so on, is currently the most widely used ray protection materials. But the ordinary cement shield is disadvantage due to the poor effect , high cost. Barite radiation protection mortar can effectively shield ray radiation. The material is composed of cement-based cementitious materials, heavy aggregate and additives, stirring with water,afterwards mixing a little auxiliary construction of nuclear anti-material. It has good ray shielding,mechanical and construction performance, otherwise barite radiation protection mortar also has good water resistance and anti-alkali corrosion characteristics. Because of these characteristics, the development of such materials have been valued for seriously. However, high-density radiation-resistant mortar is prone to stratification, segregation and sagging, which is a common problem with this materials. The barite is prepared by adding binder material, aggregate, admixture and water to prepare a mortar to meet the barite radiation protection mortar. Wherein the aggregate consists of barite sand, quartz sand and barite powder; the admixture comprises a superplasticizers, a water retaining agent, a defoamer and a dispersible latex powder. The mass ratio of each component is cement account for 23.8 ~ 30% of the total mass, heavy aggregate account for 38.2 ~ 69.23% of the total mass, common aggregate account for 0 ~ 31% of the total mass, the admixture account for 0.39% ~ 1.16% of the total mass. The barite radiation protection mortar prepared by the above method own good mechanical , waterproof and construction performance, and has good shielding effect on γ-ray. At the same time, it has been proved by practice that the construction issue solving well.By optimizing the composition can be not only obtained highly shielded ray barite composite material, but also broaden the application of barite, making barite better guardian of human safety.

The separation method of barite and fluorite
Barite often associated with fluorite, calcite, quartz and other minerals closely, and the grade is low, the dissemination size is fine, the composition is complex, so traditional gravity concentration method is difficult to make it effective separation. Flotation can be adapted to a variety of barites with complicated dissemination. Therefore, it is the main processing method of barites nowadays.
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%.
