Sulfur is mainly consumed in the manufacture of sulfuric acid, and the latter is mainly used in the manufacture of fertilizers, especially phosphate fertilizer. Now phosphate fertilizer produced by China itself cannot meet the agricultural demand and it is necessary to import more than 4 million tons every year to meet fertilizer demand. As we depend on exports to make up for the phosphate fertilizer shortage every year, the demand on sulfuric acid for phosphate fertilizer production is diminished accordingly. Now sulfur produced by China itself can essentially meet the domestic demands for fertilizer production and various industrial uses; so it is not advisable to import large amounts of sulfur and its products.
In accordance with the State's grand programme that grains and chemical fertilizers will reach three plateaus by the end of this century, by 2000 China's production of chemical fertilizers will be 31 million tons, of which phosphate fertilizer will be 6.89 million tons (high-concentration phosphate fertilizer is required to take up 40% of the total amount of the phosphate fertilizer), and in addition other industrial sectors also use acid (excluding smelter acid), the demand for pyrite will be 19 million tons (standard ore; the same hereinafter).
According to the existing production capacity plus the potential production capacity of plants under construction of the chemical industrial sector, the annual production capacity is expected to reach 8 million tons and the annual production 5.5 million tons by the end of the ninth Five-Year Plan period; for the nonferrous metals metallurgical sector the production capacity will reach 6 million tons with an annual production of 5.5 million tons by the end of the period; for the coal sector the production of sulfur concentrates will be 1.2 million tons by the end of this period. If 7 million tons (7.38 million tons in 1996) produced by other sectors and local village- and township-owned small mines are added to the above figures, it is probable that by 2000 China's pyrite production will reach 19 million tons.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,belt conveyor,cement mill Welcome all of you to visit our official website.concentrator table price:http://www.hx-crushers.com/p112.html
In 1997, the production of sulfuric acid produced from smelter fumes surpassed 4 million tons, an increase of 29.85% over 1996, which can directly increase the availability of sulfur without doubt.
Sulfur mining causes great harms to the environment and the health of men and livestock. We must take effective measures to strengthen the environmental control and protection, maintain the ecological balance and mitigate any harm to the people so as to achieve sustainable development of sulfur mining.Henan Hongxing Mining Machinery Co., Ltd is a joint-stock mining machinery manufacturing enterprise integrated in scientific research, production and marketing. It is located at the High & New Technology Industries Development Zone of Zhengzhou,China with an area of 50 thousand m2 which includes 15,000 m2 of standard heavy duty industrial workshop. Equipments are more than 160 pieces, including large and medium sized metal processing, riveting and installing equipments. There are more than 660 workers including 80 administrators with secondary and senior occupational titles and engineering technicians.
