Phosphate mineral resources associated with the recovery of fluoride production of hydrogen fluoride

Fluosilicic acid, a by-product of the phosphate fertilizer plant, is currently used in very few fields and is mainly used to produce less than 10 products such as sodium fluorosilicate, cryolite, and aluminum fluoride. The introduction of foreign technology by Guizhou Hongfu Company and the production of anhydrous hydrogen fluoride from the by-production of fluorosilicic acid from the phosphate fertilizer plant has made great progress. Hongfu Company is currently constructing an industrialized plant that produces 20,000 tons/year of fluorosilicic acid to produce anhydrous hydrogen fluoride. After the project is completed, Hongfu will become the first company in the world to recover fluorine resources and process high-grade fluorine chemical products from the phosphorus chemical production process. This opens up new ways for the comprehensive utilization of fluorosilicic acid in the phosphate fertilizer industry. It not only can greatly increase the added value of products, but also can turn waste into treasure, partially replacing China’s precious fluorite resources, and will also open up new products for fluorosilicic acid by-products. Industry chain.
In addition, Yuntianhua International Chemical Co., Ltd. Furui Company is currently conducting technical research on the efficiency of fluorine-enriched absorption, and developing technology to recover anhydrous fluorine produced by phosphor production associated with phosphate mining, in order to achieve the comprehensive development and utilization of fluorine resources.

The js series twin-shaft forced mixer equipped with this product adopts Zeyu multiple shaft-end seal technology and has stable performance. The mixing arm drives the mixing blade to force the mixing of the material in the tank body, the mixing effect is very strong, and the mixing quality is better.
