20 years of China's phosphate mining capacity from 21 million tons raised to 89.5 million tons, achieving a high concentration of phosphoric acid and phosphate fertilizer self-sufficiency over; potash industry to achieve a scratch, the level of protection up to 40% to 45%. At the same time, fertilizer mineral resources also faces six major challenges. This is the reporter from the recently held in Beijing, China Chemical Mining Association's 20th anniversary of the Fourth Council of the Association was informed of five.
According to the China Chemical Mining Association Li Haiting, as of the end of 2010, China's new found and proven phosphate 540, Sulfur 673, potassium 39. Reserves of 18.63 billion tons of phosphate rock resources identified, pyrite 5.69 billion tons, 930 million tons potash (potassium chloride). Compared with 1991, adding 2.37 billion tons of phosphate rock, pyrite added 1.097 billion tons, adding 640 million tons potash (potassium chloride), the level of protection for fertilizer production greatly increased. In 2010, domestic production of 68.07 million tons of phosphate rock, phosphate production in 1991 three times, ranking first in the world, to fully meet the domestic production of phosphate fertilizer and related industrial needs; pyrite production of 15.13 million tons, more than in 1991 increased slightly; potash production reached 3.968 million tons, 40 times the annual output of 1991.
However, the fertilizer in the growing mineral resources, while also facing challenges. Lihai Ting pointed out: First, poor resource endowment, low level of supply security, China's major mineral resources, chemical phosphorus, sulfur, less resource-poor ore more high-grade ore, difficult mining refractory, and potash resource self-sufficiency rate of only 30%; the second is based industries did not ahead of construction, mining development can not meet needs; third is a serious waste of resources, mining technology and equipment varies; four is to develop serious environmental damage, were associated with low integrated resource recovery; Fifth, resource use planning, succession and reserves disorder ; six high corporate taxes, the industry self-development problems.
