Recently, Hunan Provincial Environmental Protection Industry Association issued the "Publicity of the Results of the Evaluation of the Advanced Technology, Demonstration Project and Enterprise Credit Rating of Hunan Province in 2024", and Fortune was approved again for the advanced technology of environmental protection in Hunan Province. The "Hydrometallurgical process and wastewater defluorination technology" independently developed by Fortune won the award in the selection of Advanced Technology for Environmental Protection in Hunan Province in 2024. This technology not only represents our deep understanding of the field of environmental protection, but also demonstrates our excellence in technological innovation.

Product advantage

1 High efficiency and stability

Only one reaction precipitation, high defluorination efficiency, fast defluorination speed, stirring reaction 45 ~ 60min can complete the reaction, fluorine removal rate can reach 95% or more.

2 Small amount of slag

The amount of slag produced in the defluorination process is small, which will not lead to the entraining loss of valuable elements, and the loss rate of zinc is less than 2%. The generated fluorine-containing slag is easy to filter, and zinc can be recovered after pickling.

3 Simple process

This product can be directly put into the original solution, no need to adjust the pH value, does not affect the original production system, there is no fluorine cadmium reverse dissolution, the reaction time is short (45 ~ 60min), traditional defluorination takes 90 ~ 120min.

4 Strong adaptability

The fluorine content in the pre-fluoride solution can be adapted to a wide range (between 50-800mg/L can be processed), the requirements for mineral raw materials are relatively low, and the procurement scope is wider.
