The world's first double phosphate reverse flotation device

March 31, the world's first plastic double reverse flotation of phosphorus ore production standards in industrial test equipment Yihua Group, thus "end" of the Yichang phosphate rock hard to choose another history, which is the company following the heavy media beneficiation technology After breaking the world's problems, we have once again made major breakthroughs in the comprehensive utilization of phosphate resources.
The total investment of the device is 4.5 million yuan. Construction started in October 2005 and was completed and put into operation in 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%. P2O5 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 national key scientific research institutes and provincial and municipal science and technology sector funds and technical support, and the construction of the largest mineral processing laboratory on this basis, have been adopted by small test, test, this time The success of the industrialization test will lay a solid foundation for the next step of industrialized production. The successful operation of this device is an important milestone in China's mineral processing technology, which indicates that the heavy medium plus double reverse flotation beneficiation process developed by Yihua Group is mature and feasible.
At present, the processing cost of the beneficiation process is more than 200 yuan/ton, but it can ensure that about 20% of the phosphate rock can be selected to more than 32%, thus opening up a new way for the comprehensive utilization of low-grade phosphate rock in Yichang. Resources play an important role in realizing the sustainable development of the phosphorus chemical industry in Hubei Province and even the whole country. The successful commissioning of the plant can completely eliminate the traditional mining method of “harvesting and abandoning poverty” during the phosphate mining process. Yihua Group will make full use of this proprietary technology to build 3 million tons/year high-concentration phosphate compound fertilizer in Yichang. The large-scale mineral fertilizer combined project (including 1 million tons of diammonium phosphate/year) and 1.5 million tons/year of phosphate ore dressing plant will truly transform the advantages of phosphate rock resources into economic advantages and build resource-saving enterprises.
