Fluorite tailings are wastes produced after fluorite flotation, containing about 20% of calcium fluoride and the like. If not handled properly, it will cause pollution to water resources and the like. It is estimated that, after years of flotation, Jinhua city and county of fluorite tailings accumulation has reached millions of tons. Only Wuyi has 1.5 million tons of fluorite tailings and 200,000 square meters of concentrated piles. Some of the dumping areas constitute a major hidden danger causing geological disasters.
After two years of trial and error, in June last year, Shenlong Company successfully developed a flotation tailings flotation production line. After processing by the tailings flotation production line of Shenlong Company, the calcium fluoride content in the fluorite tailings decreased from 20% to 1%, and the pollutants in the tailings were basically removed. The waste generated after the flotation of fluorite tailings has also become a good building sand. Shenlong also cooperated with a building materials research institute in Beijing to develop successful ore-free hollow bricks. At present, the production line of non-burning bricks is about to be put into production.
A technological innovation has transformed Wuyi Shenlong Company from a polluting enterprise into a large decontamination household. Tested by Wuyi County Environmental Protection Bureau of Zhejiang Province, Shenlong Company's tailings treatment has reached the relevant standards. Zhou Aima, chairman of Shenlong Company, said: "The company is ready to invest another 10 million yuan to expand the production scale of tailings flotation, and strive to use 10 years to 'eat' all the discarded tens of thousands of tons of fluorite tailings in Jinhua counties and cities. ."
