The use of this technology to produce yellow phosphorus can reduce the use of high-grade phosphate ore without using silica, effectively save resources, and enable the procurement of raw materials nearby. After nearly three months of production trials, they explored the use of medium- and low-grade phosphate ore. Under the condition of a certain carbonate content, medium- and low-grade phosphorus ore with a malabsorption rate below 3% was selected. At present, more than 800 tons of yellow phosphorus have been produced, which makes rational use of medium- and low-grade phosphate mineral resources and reduces production costs. The average cost per ton of yellow phosphorus is nearly 300 yuan.
Jinning Company: breakthrough in the application of low-grade phosphate rock, innovative work ideas
Yunnan Jinning Yellow Phosphorus Co., Ltd., for this year's yellow phosphorus production raw material prices continue to rise, innovative work ideas, from the middle of May, the use of phosphorus pentoxide 10% to 20% of the low-grade high-silica phosphate rock Stone instead of silica means that the production of yellow phosphorus has been successful.
