Volume of production of sulfur products in general
The sulfur products include mined pyrite and dressed sulfur concentrates, as well as powdered sulfur and sulfur concentrates recovered as a by-product during dressing and sulfuric acid produced from smelter fumes. As China’s crude oil is mostly low-sulfur oil with a sulfur content 0.5% and there are limited high-sulfur sour natural gas, little sulfur is recovered as a by-product from oil and natural gas. Other kinds of sulfur are not exploited or utilized except sulfur in base metal sulfides and coals which are recovered from smelter acid and from by-product sulfur concentrates produced during coal washing.
According to the statistics of the State Administration of Petrochemical Industry, State Administration of Nonferrous Metals Industry and State Statistical Bureau, in 1997 China produced 230,200 tons of powdered sulfur, 17.2672 million tons of pyrite standard ore (sulfur-containing concentrates) and 20.03 million tons of sulfuric acid (or 20.37 million tons according to the Statistical Yearbook of China). Pyrite and sulfur acid are China’s main products of sulfur-bearing ores.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,cone crusher,ball mills Welcome all of you to visit our official website.bucket sand washer:http://www.hxjqchina.com/product-list_29.html
China ranks third in the production of pyrite and powdered sulfur containing the sulfur equivalent of 6.27 million tons, following the United States and Canada. China is the second leading producer of sulfuric acid, next to the United States.The structure of the pyrite (standard ore) production is: mines of the chemical sector, 6.76 million tons; mines of the nonferrous metallurgical sector, 4.622 million tons; the coal sector, 43,500 tons; others, 5.8417 million tons.
The structure of the sulfuric acid production is: acid from pyrite, 14.239 million tons; acid from smelter fumes 4.287 million tons; acid from powdered sulfur 1.083 million tons; acid from gypsum (mainly phosphatic gypsum), 234,000 tons; others, 187,000 tons.
