Recently, the exploration staff in Kaiyang County, Guizhou Province found a large phosphate, proven phosphate rock resources amounted to 801 million tons, equivalent to China’s largest phosphate – Kaiyang phosphate 22 years, the total amount of mining 2 times.

It is understood that the phosphate layer distribution range of nearly 50 square kilometers, the average thickness of 4.49 meters, the average grade of ore is a grade of high quality phosphate rock.
First of all, we first look at what kind of large phosphate rock:
First, China’s large-scale phosphate rock
“Sanyang Kai Tai,” the first of the Kaiyang phosphate, is well-known large-scale rich phosphorus-producing areas at home and abroad. Located in the hinterland of Guizhou, Kaiyang County West. Production area, including Ma Ping, with sand dam, sand dam soil, bliss, cattle rush, two fork river, new slope and other ore, the area of about 85Km2.

The area of phosphate rock reserves of more than 420 million tons, accounting for about 16% of the province’s total. Kaiyang phosphate is particularly famous for the quality of the ore, the region P2O5 content of more than 30%, an average of 34.2%, become China’s rare phosphorus-producing areas, and without mineral processing, can be used for high concentrations of phosphate fertilizer production. After years of exploitation, the rich ore accounted for the country to maintain the total amount of about 28% of the rich ore.
Kaiyang phosphate mine reserves of large reserves, high grade, less harmful impurities, heavy metal elements cadmium content is low, which content of more than 32% of the phosphate reserves accounted for 78% of the total reserves, is currently the only non-beneficiation can be Direct production of high concentrations of phosphorus and fertilizer important raw material base, is the ideal wet fertilizer and raw materials and production of pollution-free green phosphorus chemical products of high quality raw materials.
And Guizhou Kaiyang Qi called “Sanyang Kai Tai” is the Yunnan Kunyang, Hubei Xiangyang. Other large domestic phosphate rock is as follows:
| Chitosan oligosaccharide |
Second, the status and distribution of phosphate minerals
Phosphate ore industry chain:
1, the distribution of reserves in various regions of China
In the low-grade ore and more ore is less of China’s phosphate resources, one of the characteristics.
| Bacillus thuringiensis |
93% of China’s phosphate deposits are low grade, high impurity content, P2O5 is more than 30% high grade phosphate reserves of only 1.069 billion tons, accounting for only 8.12% of the total reserves, even if the grade is greater than 26% Reserves will not exceed 3 billion tons, the average grade is only 16.95%.
China has proven phosphate resources in 27 provinces autonomous regions, Hubei, Hunan, Sichuan, Guizhou and Yunnan are phosphate-rich areas, 5 provinces have identified the reserves of mineral resources (ore) 13.5 billion tons, accounting for 76.7 %, According to the average grade of mining ore, 5 provinces of phosphate rock reserves (P2O5) 2.866 billion tons, accounting for 90.4% of the country.
2, the world’s reserves distribution
| Stannous Sulphate |
Up to now, the global phosphate rock reserves of 67 billion tons, mainly in Africa, North America, Asia, the Middle East, South America more than 60 countries and regions, of which more than 85% of economic reserves concentrated in China, the United States, Morocco, And five countries in Jordan. Only Morocco accounted for 75% of the global total, while China is also one of the major phosphate rock.
Third, the relationship between supply and demand of phosphate rock
1, global phosphate production
US Geological Survey released in 2015, the global phosphate production data show that in 2014 the world’s total output of 220 million tons of phosphate rock, down 22%.
| Sodium selenite |
At present, the sustainable exploitation of phosphate rock resources is gradually reduced, and the origin is mainly concentrated in a few countries, the scarcity and irreplaceability of phosphate rock resources, the decision of this resource should be higher than other resources.
Data show that in the world’s 67 billion tons of phosphate reserves, Africa and the Middle East together close to 80% of the world, China only 3.7 billion tons of reserves to 2014 production estimates, China’s phosphate rock can be exploited less than 40 years, Far below the average annual mining time, not to mention with Morocco, Algeria these “high levels of phosphorus ore” gap.
2, China’s supply and demand situation
| Benzalkonium chloride |
At present, China can be mined reserves of phosphate reserves of only 2.111 billion tons of reserves, of which more than 30% of the rich ore is only about half of the current mining speed of about 20 years can be mined. This means that the phosphate resources will soon be depleted in the future, so the phosphate resources has been China’s qualitative as a strategic resource.
Before the introduction of national planning, some local governments have introduced the relevant policies and regulations of phosphate mining. According to the relevant data, global phosphate consumption growth has been higher than the global population growth, is expected in 2014-2018 years, phosphate consumption will be 9.2% growth rate, as shown below:
| Gamma-PGA (gamma polyglutamic acid) |
China’s phosphate rock industry, has been the lack of a strong phosphorus chemical industry to match. Small and scattered, the strength is not strong, with the phosphate rock resources and phosphorus chemical industry a series of management and development decision-making, history gave the industry a rare opportunity.
The introduction of national policy in 2015 conveys a clear signal that the country is paying more and more attention to phosphate rock resources.
