Yield Map of Mercury Products in China
As of the 1990s, China has had a total of 11 major Hg-producing enterprises (excluding township enterprises), of which 1 produces by-product mercury and 2 recover waste mercury. The country’s integrated mercury ore mining-dressing-smelting capacity has been at 900 t/a, its ore mining-dressing capacity at 1,200 t/a (mercury metal), and its ore smelting capacity at 860 t/a (primary mercury). Enterprises annually producing over 100 tons of mercury have been the Guizhou, Wuchuan and Tongren mercury mines.
According to the mercury resources distribution and constructional conditions of China, the 11 State-owned mercury-producing enterprises are sited mainly in the southwest, northwest and south-central parts of the country. Their names and locations are as follows: in the southwest part are the Guizhou Hg mine (in the Wanshan Special Economic Zone of Guizhou Province), the Wuchuan Hg mine (in the Daping area, Wuchuan County, Guizhou Province), the Tongren Hg mine (in Tongren County, Guizhou Province), the Danzhai Hg mine (dealing chiefly with the recovery of waste mercury; in Danzhai County, Guizhou Province), the Huangping Hg mine (in Huangping County, Guizhou Province), the Xikou Hg mine (in Xiushan County, Sichuan Province), and the Youyang Hg mine (in Youyang County, Sichuan Province); in the northwest part are the Xunyang Hg mine (in Xunyang County, Shaanxi Province) and the Tongde Hg mine (in Tongde County, Qinghai Province); in the south-central part are the Xinhuang Hg mine (dealing mainly with the recovery of recycled mercury; at Jiudiantang, Xinhuang County, Hunan Province) and the by-product enterprise of the Shaoguan smelter (in Shaoguan City, Guangdong Province).As the professional manufacturer of complete sets of mining machinery, such as cement plant,cement making plant, Henan Hongxing is always doing the best in products and service.

Major technical economic criteria of mercury ore mining and dressing in the whole country
Since the 1980s, China has attached importance to the readjustment of the structure of mercury products. In the 1970s, its mercury products were confined to metal mercury and cinnabar, while now nearly 20 mercury products are being produced. Furthermore, some of its intensively processed products such as cinnabar, red mercury oxide, red mercury bromide and mercury chloride are being exported.
