The distribution of phosphate rock resources in the world is relatively concentrated. Due to the scarcity of phosphate rock resources and the protection of domestic resources, the world's phosphate rock output has slowed down. The grade of phosphate decreased and exports decreased; while the international demand for phosphate rock increased. At the same time, international energy prices rose, mining costs and logistics costs rose, and international phosphate rock prices remained high. In China, with the remediation of small phosphate mines and the concentration of phosphate rock resources, the domestic phosphate rock mining order has improved, but the supply of rich ore will be tight in the future, and low- and medium-sized mines will become the mainstream. With the combined effect of strong demand, domestic phosphate rock prices will also remain high.
