Liumei gold deposit is located in Fuliuling gold mining area of Longshan mine field in Guigang, Guangxi, China. The deposit belongs to carlin-type gold deposit. Arsenopyrite and pyrite are the major gold-bearing minerals in the deposit. In order to know the existing state of gold in the deposit, auriferous features analysis, gold leaching extraction analysis and crystal structure determination analysis on arsenopyrite and pyrite are carried out. In arsenopyrite, about 25% of the Au exist in the form of lattice, and 75% exist in the form of ultra-microscopic inclusions. Fluid inclusion microthermometric and REE geochemical studies indicate that the Liumei gold deposit is a meso-epithermal hydrothermal deposit, in which the mineralizing material is related to the strata.
