Relation between supply and demand of sulfur
The sulfur supply of China is 8.6393 million tons of sulfur. China itself can produce 17.2672 million tons pyrite standard ore (sulfur-containing concentrates), 230,200 tons of powdered sulfur, 4.287 million tons of smelter acid and 234,000 tons acid from gypsum; they combine to amount to 7.8561 million tons of sulfur equivalent or 90.93% of the total supply.
The net imports of powdered sulfur and sulfuric acid are 739,900 tons and 123,600 tons respectively, amounting to 783,200 tons of sulfur equivalent or 9.07% of the total supply.Sulfur produced by China itself is mainly used to meet the domestic demand and the short part of the supply relies on imports. The imports and exports of sulfur commodities in 1997 are presented in Table 4.5.5. Imports are mainly from Japan, Canada, France and Taiwan, and exports are mainly to Japan, Korea, Vietnam and Hong Kong.
The total volume of imports and exports of sulfur commodities of China in 1997 was US $ 48.49 million, lower than that (US $ 61.748 million) in the previous year, of which the export volume was US $ 2.075 million (it was US $ 2.79 million in the previous year) and the import volume was US $ 46.415 million (it was US $ 58.958 million). In 1999 China still imported appreciable amounts of powered sulfur, sulfuric acid and fuming sulfuric acid.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,cement mill,mobile crushing station Welcome all of you to visit our official website.drum dryer:http://www.hx-china.com/15.html
The great majority of China’s sulfur-bearing ore production goes for the manufacture of sulfuric acid. Among other things, 14.239 million tons of pyrite ore (standard ore) is used in sulfuric acid production, accounting for 82.46% of the country’s total pyrite production. In 1997 China’s consumption of sulfuric acid was 19.91 million tons. Its consumption pattern is: chemical fertilizers, 72.62%; chemicals, 14.49%; other industries, 12.81% (Table 4.5.6). The percentages of sulfuric acid used in the manufacture of various kinds of chemical fertilizer in the total consumption are given in Table 4.5.7.
According to relevant data of the Ministry of Land and Resources(Annual Report of Mineral Resources of China,1997), in 1997 China’s sulfur-bearing standard ore and powdered sulfur in stock were about 1.97 million tons and 22,000 tons respectively. The detailed tonnage of sulfuric acid in stock is unclear.
To sum up, it is estimated that China’s apparent consumption of sulfur (sulfuric acid included), comprising all items of uses of sulfuric and sulfuric acid and the amounts of exports and stocks, is about 21 to 22 million tons of sulfur standard ore, or about 7.3 to 7.7 million tons of sulfur equivalent.
