Recently, the world's first plastic double reverse flotation of phosphorus ore production standards in industrial test equipment Hubei Yihua Group. This is another major breakthrough in the comprehensive utilization of phosphate rock resources after the company's heavy medium mineral processing technology has solved the world's problems.

The total investment of the device is 4.5 million yuan. Construction started in October 2005 and was completed and put into operation at the end of March 2006. At present, the device is running smoothly, all economic and technical indicators are up to standard, the magnesium content is less than 0.6%, and the recovery rate is greater than 90%. P205 is greater than 32% and the ratio of sesquioxide to phosphorus is less than 10%. The project was put into production from the project to the funding and technical support Institute Lianyungang, Qingdao Chemical Industry Design Institute and other key national research institutes and provincial and municipal science and technology sector, and on this basis, the construction of the largest mineral processing laboratory, has After passing the small test and the pilot test, the success of this industrial test will lay a solid foundation for the next step to achieve industrial production.
At present, the processing cost of the beneficiation process is 200 yuan/ton or more, but it can ensure that more than 32% of the phosphate rock with 20% grade can be selected. This effectively identifies Yichang phosphate resources and finds a technically feasible, scientific and economical beneficiation process route for the sustainable development of the phosphorus industry in Hubei Province and even the whole country, achieving a virtuous cycle of resource conservation and rational development and utilization.
The successful commissioning of the device can completely eliminate the traditional mining methods of “harvesting and abandoning poverty†in the process of phosphate rock mining, and provide technical support for breaking through the worldwide technical problems of Yichang phosphate rock ore beneficiation. During the “Eleventh Five-Year Plan†period, Yihua Group will make full use of this proprietary technology to build a large-scale mineral fertilizer combined project of 3 million tons/year high-concentration phosphate compound fertilizer and 1.5 million tons/year phosphate ore dressing plant in Yichang. Yihua has built the country's largest phosphorus chemical industry base.
