tin beneficiation plant

Gold for crystal at room temperature, the cubic system, vertical lattice in heart, is a rare good natural crystal shape, often irregular granular, crumb, flake, mesh, dendritic, fibrous and spongy. For gold, pure gold containing tin beneficiation plant impurities when its color can be change accordingly.

Gold has bright luster, under the white light reflectivity of 74% on average, with the increase of silver content, higher reflectivity, gold increase hardness, density decreased. Bad the volatility of gold, and above the melting point temperature to 1300 ℃ almost no volatile, but in the gas and CO atmosphere more volatile. China's gold
Resource is rich, almost every province has a portable gold ore screening resources, proven mining area in 1265, total reserves of 4265 tons, reserves of 1159.1 t, 787.4 t reserves, the world in the 7th. Our country has been found, there are 38 if including 46 species, subspecies and variety according to the national mineral reserves
Summary statistics, by the end of 1996, of which 2515.8 t rock gold, and accounted for 59%, 557.42 t placer gold, accounted for 13.1%, a total of 1191.56 t, associated gold accounted for 27.9%. Gold resources are widely distributed in China, in addition to Shanghai, Hong Kong special administrative region, in the national various provinces, autonomous regions and municipalities have mining output. Portable gold ore screening in China
Resources on the regional distribution is not balanced, the eastern region wide distribution, gold type. Placer gold is concentrated in the northern edge of the northeast region and the mainland three giant deep fracture system controls the overall distribution of rock gold deposit, the middle and lower reaches of the Yangtze river nonferrous metal clusters is associated with gold of alternaria alternata (total)
The ground.

Gold deposits are mainly distributed in 9 metallogenic province:

A. the placer gold in north mining area. Ho mainly coltan ore processing in heihe, karma and birch in sichuan area of sand gold mine, belongs to the river alluvial deposit.

B yan liao, the mining area. Including the eastern jilin and some of the gold deposits in northern hebei. Most of which are found in pre-sinian gneiss, slice The oxygen content in rock and granodiorite gold quartz vein deposit.Shandong gold mining area

C. This area gold ore reserves and production are the first in the nation.

D southeast gold mining area. MaiJin including hunan, guangxi, more for plate creek, the mineralization of SLATE and side stream containing gold quartz vein of subgroup, gold deposits in the region is more, but the scale is small, mainly Portable gold trommel is the xiangxi gold mine.

E - qilian mountain in qinling gold mine. Veins Carbon in Pulp in the region, high grade, polymetallic intergrowth of characteristics. Representative mines such as qinling mountain, valley, tongguan gold mine.

Keelung, Taiwan gold mining gold deposits are mainly

G string of reinforced sand gold, gold, red fang featuring mountains gold mine, peony pit gold mine. H gold mining area in xinjiang. In northern xinjiang and al tai shan district MaiJin in southwest and southeast of placer gold.

F jinshajiang river basin and sichuan basin in southwest of some river terrace placer gold mining area.
