一、选金方法目前常用的选金方法有:混汞、重选、浮选、氰化法四种。根据含金矿石的性质及矿物可浮性的差异,往往采用联合选金工艺流程。目前选金工艺的总发展趋势是采用手选、混汞或重选、浮选和氰化法,尤其以全泥氰化炭浆法为主要发展趋势。 First, the gold method Currently used gold methods are: amalgam, re-election, flotation, cyanide four. According to the nature of gold-bearing ores and the flotability of minerals, the joint gold selection process is often used. At present, the general development trend of the gold process is the use of hand-selected, amalgamation or re-election, flotation and cyanidation, especially the whole mud cyanide carbon slurry as the main trend.
