Low-quality phosphate mineral enrichment technology developed successfully

Recently, Chengdu Leshi Chemical Engineering Co., Ltd. and Sichuan Mabian Boundless Mining Co., Ltd. have jointly developed a new low-quality phosphorus-enriched phosphorus-producing technology that can increase the ore grade by 8 to 10 percentage points.

It is reported that the new phosphorus-rich technology of low-quality phosphate minerals is obtained by calcining or drying the pellets after beneficiation, and the low-grade phosphorite ore is calcined into balls. These three kinds of enrichment processes will lower the P2O5 content in low-grade phosphate ore from 22%. Increased to 31.96%, while the SiO2 content has also been greatly improved. The use of calcined into the ball can also reduce the CO2 content to less than 0.5%.

The application of this new technology to yellow phosphorus producers in poor mine areas shows that 10,000 tons of yellow phosphorus can save 7,100 tons of coal (equivalent to 5,100 tons of standard coal) and save electricity 42 million kwh (equivalent to 1,900 tons of standard coal). . Produced by the calcined yellow phosphorus to remove some of the arsenic, fluoride and organic matter, arsenic content decreased, the product quality significantly improved.
