Barite barium salt products

Barite barium salt products

Answer:

In barite as raw material in the production of barium salt products in addition to lithopone (Xin Beibai), is mainly barium carbonate, barium chloride, barium hydroxide, barium nitrate, barium sulfate, barium titanate, barium molybdate and some fine chemicals.
Lithopone lithopone (Xin Beibai) is a white powder, the average particle size of 0.3 ~ 0.5 m, insoluble in water, and the effect of hydrogen sulfide and the lye, acid liquid is decomposed to release hydrogen sulfide. The sun will change color after a long period of time, but the primary color can still be restored in the dark. The production of lithopone raw material except barite, and Zinc Oxide, sulfuric acid, coal powder, the main chemical reaction:ZnO+H2SO4=ZnSO4+H2OBaSO4+2C=BaS+2CO2ZnSO4+BaS=ZnS BaSO4
The main raw material of barium carbonate is barite, limestone and coal. The technological process is as follows: barite, coal powder, pulverization, baking, heating, steam leaching, clarification, carbonization, adding soda ash, steam desulfurization, washing, filtering, drying and packing.
Barium chloride, barium chloride, is a white, lustrous monoclinic crystal that loses water when heated to 113 DEG C and becomes a white powder. Soluble in water, solubility increases with increasing temperature. The aqueous solution is bitter and salty, and has toxic effects on people, livestock and insects.The main raw materials for barite, coal, hydrochloric acid or chlorine, calcium chloride and so on. Preparation method of hydrochloric acid, calcium chloride, chlorination. Hydrochloric acid is prepared by reaction of barite with coal powder after reduction roasting with hydrochloric acid. Calcium chloride process is also first reduction roasting, and then by leaching, desulfurization and other treatment system. The chlorination reaction with chlorine to barium sulfide liquid barium chloride solution, then processed by the system.
