The distribution of phosphate rock resources in the world is relatively concentrated, the scarcity of phosphate rock resources and the protection of domestic resources, the world's phosphate rock production slowed down, 167 million tons in 2006, the output decreased by 2.9 percentage points compared with 05 years, the grade of phosphate rock declined, exports decreased, and the international demand for phosphate rock increased. At the same time, international energy prices have risen, mining costs and logistics costs have risen, and international phosphate rock prices have remained at a high level. Domestically, with the remediation of small phosphate rock, the concentration of phosphate rock resources, the domestic phosphate mining order has improved, but the future supply of rich ore will be tightened, medium and low ore will become the mainstream, affected by international prices, and the domestic mining cost and the strong demand for phosphate rock, the domestic phosphate rock price will also remain high.
