China's magnesite resources are very rich, with reserves of about 2 billion tons, ranking first in the world, of which the recoverable reserves are 1 billion tons. Currently consists of magnesite ore production of magnesium products are mainly for light burning magnesium powder and all kinds of refractories, magnesium lack of high value-added products, especially with the advancement of technology, metallurgical industry, the amount of refractory dwindling, so as to Ling The economic benefits of the production of refractory materials from magnesium ore as raw materials have generally declined. However, with the rapid development of the chemical industry and increasingly strict environmental protection standards, the use of magnesium products in the fields of plastics, rubber, printing and dyeing, paper, medicine, agriculture, environmental management and other fields has maintained steady growth. How to make full use of China's unique advantages of magnesium resources, develop and produce magnesium salt series products that can meet market demand, and transform the advantages of magnesium resources into economic advantages, which is of great practical significance for the long-term development of magnesite enterprises.

Based on market research, Tsinghua University Nuclear Energy Technology Design Institute has developed a series of new products, such as magnesium sulfate, magnesium oxide, magnesium carbonate and magnesium hydroxide, which have advanced technical routes and reasonable processes. The magnesium sulfate produced by this process has high purity, meets the quality requirements of pharmaceutical grade, and the crystal size is controlled, and different crystal products can be produced according to market conditions. Magnesium carbonate and magnesium oxide are the starting materials of magnesium sulfate. Due to the high purity of the raw materials, the purity of the downstream products is correspondingly improved, and the pharmaceutical grade magnesium carbonate and silicon steel grade magnesium oxide can be obtained by the process. Magnesium hydroxide products further demonstrate the flexibility of the process, in addition to the production of high-purity magnesium hydroxide products and extended to high-purity magnesium fluoride. In the equipment aspect, the drying system uses a continuous system to ensure the stability of product quality. At the same time, the entire process can adjust the production volume of each product according to market conditions, so the project has strong anti-risk ability.
We have built a production demonstration plant with an annual output of 6,000 tons by cooperating with Shandong Hengxin Magnesium Co., Ltd., a state-owned large-scale magnesium mine with strong technical strength in China. Trial production is currently underway and the market is good. The existing intention is to expand into a 20,000-ton magnesium salt production plant in cooperation with large domestic enterprises with magnesite resources, and contribute to transforming China's resource advantages into economic advantages.
Technical indicators and application description The main products of magnesium sulfate meet the quality requirements of pharmaceutical grades, and magnesium hydroxide meets the requirements of quality of flame retardant products. Magnesium carbonate and magnesium oxide meet the quality requirements of industrial grade products. Magnesium sulfate is mainly used in the fields of monosodium glutamate fermentation, food additives and medicines; magnesium hydroxide is mainly used for burning of plastic materials and coatings; magnesium carbonate and magnesium oxide are important additives for daily chemical products such as rubber, ceramics or electronics. The filler used in the product. SiC binding brown corundum abrasive brick making process becomes a raw material stage by weight 1 ~ 3mm particle size of from 33% to 37% of corundum, corundum particle size ≤1.2mm 12% to 17%, ≤0.088% of silicon carbide particle size ~ 20% 24% particle size of aluminum oxide 7% ~ 11% 1 ~ 5mm, and a particle size of 0.088mm aluminum oxide of 16% to 20%, the amount of a saturated aqueous solution of phosphoric acid is 6% to 8% of the amount of solids, The sintering temperature is 650~700 °C. Compared with the prior art, the production process has the characteristics of good high temperature resistance, good thermal shock stability, resistance to quenching and rapid heat, chemical corrosion resistance, pressure resistance and wear resistance, and thus has good popularization and use value.
