China’s largest combined fertilizer and fertilizer project, Dagukou Mineral Fertilizer Project, has undergone six years of hard work by thousands of builders. It has recently been known as Hubei Jingjing Phosphorous Chemical Industry Co., Ltd., which is known as the “Central China Phosphorus Metropolis”. Put into operation. The first batch of 1500t heavy calcium finished products were matured and granulated at the beginning of June. The Dagukou project is designed to produce 560,000 tons of heavy superphosphate, 1.5 million tons of annual mining, 1.5 million tons of beneficiation, 600,000 tons of sulfuric acid, 200,000 tons of phosphoric acid, and 12,000 tons of aluminum fluoride, including 20 In a single project, the process and scale of the three devices including heavy calcium, sulfuric acid and phosphoric acid are the highest in the country. This project is a key construction project of China’s “Eighth Five-Year Plan” with a total investment
