In the 20 years of China Chemical News, China's phosphate production capacity increased from 21 million tons to 89.5 million tons, achieving high concentrations of phosphate compound fertilizers and phosphate fertilizer self-sufficiency; potassium fertilizer industry realized from scratch, the degree of protection increased to 40% ~ 45%. At the same time, chemical fertilizer mineral resources are also facing six major challenges. This reporter learned from the 20th anniversary of the founding of the China Chemical Mining Association and the fourth meeting of the fifth session of the Association held recently in Beijing.
According to Li Haiting, chairman of the China Chemical Mining Association, as of the end of 2010, China had newly discovered and identified 540 phosphorite mines, 673 mines, and 39 potassium salts. The reserves of phosphate rock were identified as 18.63 billion tons, *5.69 billion tons of iron ore, and 930 million tons of potassium salt (potassium chloride). Compared with 1991, there were 2.37 billion tons of new phosphate rock, 1.097 billion tons of new iron ore, and 640 million tons of potassium salt (potassium chloride), which greatly increased the protection of fertilizer production. In 2010, China produced 68.07 million tons of phosphate ore, which was three times the output of phosphate rock in 1991, ranking first in the world, fully satisfying the needs of domestic phosphate fertilizer and related industrial production; * The output of iron ore was 15.13 million tons, compared with 1991. The annual growth was slightly; the output of potash reached 3.968 million tons, which was 40 times that of 1991 production.
However, as fertilizer resources continue to grow, they also face challenges. Li Haiting pointed out: First, poor resource allocation and low degree of supply security, China's main chemical mineral resources, phosphorus, * rich ore resources less rich, difficult to pick and difficult to choose, and potassium salt resources self-sufficiency rate is only 30%; Second, the basic industry did not Advance construction, mining development can not meet the needs; Third, serious waste of resources, mining technology and equipment level varies; Fourth, the development environment is seriously damaged, a total of associated resources associated with low recycling; Fifth, resource utilization planning, succession and reserve disorder Sixth, corporate taxation is high and the industry itself is difficult to develop.
