The main useful minerals Meiyukou collophane phosphate ore, gangue minerals mainly dolomite, chalcedony quartz-like, grain-like quartz or the like followed, marine deposit silicon metal calcium phosphate rock type, mineral enriched Difficulty After the system has passed the systematic condition test, the process structure test, the clear water back comparison test, one of the newly recommended processes, the return flow process, after 72 hours of continuous operation, the final indicators obtained exceeded the test requirements. The index of the Dagukou Phosphorus Deposit is relatively large. It has been determined to build a joint enterprise of mining, selection, acid, fertilizer and phosphorus chemicals. After the project is completed, it can produce 690,000 tons of phosphate concentrate per year and can be processed locally. Products such as heavy calcium phosphate have alleviated the current shortage of phosphate fertilizer demand in China, and can replace the amount of imported phosphate fertilizer, save a part of foreign exchange, and have significant economic benefits.
