Production distribution of sulfur mines in China mainland
The nonferrous metal mines of the nonferrous metals metallurgical sector that produce by-product sulfur concentrates are distributed widely in more than 20 provinces (region); they are mainly the Hongtoushan copper mine, Liaoning; the Anhui Tongling Nonferrous Metals Corp.; Jiangxi Copper Industry Corp.; the Hubei Daye Corp.; Gansu Baiyin Nonferrous Metals Corp.; Shaanxi Jinduicheng Molybdenum Industry Corp. and Yunnan Tin Industry Corp. Their total production capacity is about 4.2 million tons per year.
The sulfur production of the coal sector is mainly from recovering pyrite during coal washing and mining of pyrite ore beds occurring together with coal beds. In the coal sector the sulfur dressing plants or coal mine enterprises that mine by-product pyrite besides coal are widespread, mainly in Sichuan, Henan Shandong, Shanxi, Hebei, Jiangxi, Hubei, Yunnan and Guizhou. The important enterprises are the Nantong Mining Office, Sichuan, the Kailuan Mining Office and Handan Mining Office, Hebei, the Shenyang Mining Office, Liao-ning, the Fengcheng Mining Office, Jiangxi, the Liuzhi Mining Office, Guizhou, and the Wuda Mining Office, Inner Mongolia. In 1997 the by-product pyrite production capacity of the nationwide coal sector was 1.3 million tonsper year, but most mines have been suspended or are operating under capacity and the production declines steadily. In 1997 only about 44,000 tons of sulfur concentrates were recovered.
In the oil and natural gas sector and petrochemical sector, sulfur recovered as a by-pro-duct is mainly from natural gas fields in Sichuan, with a processing capacity of 140,000 tons per year, and now 69,600 tons of sulfur have been recovered. Less commonly it comes from crude oil in refineries and a small amount from oil shale, both contributing 39,000 tons of recovered sulfur. The production of the above-mentioned three sources totals 108,600 tons of sulfur, equivalent to 350,000 tons of standard ore.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,sand washing plant,sand washer Welcome all of you to visit our official website.iron ore concentrator:http://www.hxjqchina.com/n28.html
In addition to the sulfur produced by the aforesaid industrial sectors, collective mining enterprises of villages and townships also produce 6 to 7 million tons per year of pyrite. The major sulfur producing enterprises of China and index of these enterprises are shown in Fig. 4.5.2.
According to the Yearbook of Chemical Industry of China, China’s sulfuric acid production in 1997 was 20.03 million tons (or 20.37 million tons according to the Statistical Yearbook of China), an increase of 7.27% over 1996, setting a historical record. Of this, 71.52% came from pyrite, 21.53% from smelter fumes, 5.44% from powdered sulfur, 1.2% from gypsum and 0.31% from others. The provinces with an annual production exceeding 1 million tons are: Liaoning, 1.087 million tons; Jiangsu, 11.894 million tons; Anhui, 1.396 million tons; Shandong, 1.383 million tons; Hubei, 1.517 million tons; Hunan, 1.104 million tons; Guangdong, 1.378 million tons; Sichuan, 1.661 million tons; Yunnan, 1.44 million tons.
