General situation of sulfur resources in nature
Sulfur resources are very abundant in China. In this section total sulfur resources include sulfur reserves and potential resources. Sulfur reserves refer to reserves of pyrite, by-product pyrite and native sulfur explored through geological exploration; sulfur potential resources include the unexplored part of resources of sulfur recoverable from oil, natural gas, nonferrous metal sulfides, coal, oil shale, gypsum, anhydrite, alunite and arsenic and out-of-balance reserves of pyrite. It is estimated that China’s total sulfur resources amount to 13 billion tons. By 1997 the retained sulfur reserves were 1.451 billion tons, accounting for 11.2% of the total resources, and the sulfur potential resources make up over 88%. The potential resour-ces of sulfur in coals and gypsum of China are enormous. Only sulfur in coals accounts for over 74% of the potential resources; sulfur in gypsum is second with about 11.4% of the potential resources; sulfur in nonferrous metals, oil, natural gas and alunite and the out-of-balance reserves of pyrite etc. together constitute 3.4%.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,hammer crusher,sand washing plant Welcome all of you to visit our official website.vibrating grizzly feeder:http://www.hx-crushers.com/p20.html
By 1997, China had possessed 747 sulfur mining areas with retained sulfur reserves of 1.451 billion tons, of which pyrite sulfur reserves were 806 million tons, accounting for 55.6% of the total, by-product pyrite sulfur reserves were 324 million tons, accounting for 22.3% of the total, and native sulfur reserves were 321 million tons, taking up 22.1% of the total.
Sulfur resources in the world are very rich. According to the Mineral Commodity Summaries, 1997, the world’s sulfur reserve base was 3.5 billion tons. China’s categories A+B+C reserves may be largely compared with the world’s reserve base. China’s retained sulfur reserves of categories A+B+C as of 1997 were 386 million tons; it ranked second, following Iraq.
