The products are widely used, and the most consumed in the industry is pure antimony trioxide (white) and sodium antimonate. The production method of chalk is divided into fire method and wet method. Fire there are direct and indirect methods. The former is composed of stibnite direct output in line with the requirements of antimony trioxide, which is made of a metal antimony oxide, volatile re-sublimation system. The indirect method is widely used in the industry, and the equipment used is mostly a reverberatory furnace or an electric furnace, and the purity of the product can reach 99.0% to 99.8%. China's chalk production uses a reverberatory furnace with a special cooling device to meet the first-class standard specifications. A novel wet i.e. chlorinating agent, through two main processes of hydrolysis and chlorination, may be concentrates or antimony sulfide ore concentrates Jamesonite lead directly in line with the production of the chemical composition of antimony trioxide antimony white zero-order requirements. The production of sodium citrate is divided into fire and wet methods. The fire method is to mix the chalk with a certain proportion of caustic soda and saltpeter at a high temperature, and then crush it after cooling. The fire method has been eliminated due to its high cost and poor quality. The wet method is divided into an indirect method and a direct method. The indirect method is to produce a product by reacting cerium oxide or cerium oxychloride with an oxidizing agent such as alkali or hydrogen peroxide. The indirect method has good quality, but the cost is high and the use is less and less; The leaching process of the direct method is the same as that of the alkaline wet smelting. The difference is that the leaching solution is subjected to air catalytic oxidation to form sodium citrate precipitate. This method has low cost and is widely used in the treatment of brittle sulphur bismuth concentrate. Can support service according to customer's requirements.
