臭氧氧化—氰化处理黄铁型难选金、银矿石在原生矿石中金以微细粒与原生矿物黄铁矿、砷黄铁矿、磁黄铁矿共生,因此不能被回收。典型的金、银难选矿石中,金、银和硫化物共生,氰化之前需要氧化预处理。目前,应用的预处理方法主要有:焙烧、高压或低压氧化、化学氧化和细菌氧化。这
Ozone oxidation - Cyanide treatment of iron hard gold, silver ore in the primary gold in fine particles and primary minerals pyrite, arsenopyrite, pyrrhotite symbiosis, it can not be recovered. Typical gold, silver refractory ore, gold, silver and sulfide symbiosis, cyanide before oxidation pretreatment. At present, the application of pretreatment methods are: roasting, high pressure or low pressure oxidation, chemical oxidation and bacterial oxidation. This
