China's low-grade phosphorus resources account for more than 90%

According to the "China Mineral Resources Report" officially released by the Ministry of Land and Resources, as of the end of 2010, China has newly discovered and identified 540 phosphate mines and 673 sulfur mines. The reserves of phosphate rock resources were found to be 18.63 billion tons, and pyrites were 5.69 billion tons. Compared with 1991, phosphate rock increased by 2.37 billion tons and pyrite increased by 1.097 billion tons, which greatly improved the production of fertilizer.

Chang Yizhi, a researcher in the chemical industry of China Investment Consulting, pointed out that although the proven reserves of phosphate rock and pyrite in China have increased by a large margin compared with the past, this has certain positive significance for ensuring the production of chemical fertilizers in China. However, the report also shows that in China's phosphate rock, more than 30% of the rich ore only accounts for 8.5%, while the low-grade and high-grade phosphorus resources that can not be directly utilized account for more than 90%. Therefore, it is particularly important to improve the utilization rate of phosphate mineral resources in medium-grade grades.

At present, domestic phosphate rock producing areas and related enterprises have paid more and more attention to improving the utilization rate of low-grade phosphate rock. At present, the selection of low-grade phosphate ore in Yunnan, Guizhou, Hubei and other places in China has basically achieved industrialization; domestic low-grade phosphate ore is directly used in industrial phosphoric acid production technology has also made a major breakthrough; in addition, domestic fertilizer production enterprises It is also actively exploring new ways to produce phosphoric acid and compound fertilizers in low-grade phosphate rock. It is expected that the improvement of the utilization of medium-grade phosphate rock resources in the future will become the development focus of China's phosphate fertilizer industry.

According to the “2011-2015 China Phosphate Fertilizer Industry Investment Analysis and Prospect Forecast Report” issued by China Investment Consultant, about 80% of China's phosphate ore consumption demand comes from the phosphate fertilizer market. In the production process of phosphate fertilizer, phosphate rock accounts for about phosphate fertilizer production. 25%-50% of the cost. In recent years, due to the rapid growth of domestic phosphate fertilizer production capacity and the fact that most phosphate fertilizer producers love to enrich and abandon poverty, the reserves of high-grade phosphate ore in China have become less and less.

Zhang Yulin, research director of China Investment Consulting, pointed out that due to the fact that the domestic phosphate ore reserves have become less and less, the state has increased the control of phosphate rock resources in recent years, and the policies of phosphate resources at all levels have been frequent. The rare properties of phosphate rock are increasing day by day. It is expected that the supply of domestic phosphate rock will be further reduced in the future, which will also make domestic related enterprises pay more attention to the utilization of low-grade phosphate rock.
