Optimization of Biooxidation Pretreatment Process of Hard-to-leach Gold Ore

Wang Yingru Zhong Kangnian Wei Yihe(Wuhan Institute of Chemical Technology)  
The optimation of biooxidation pretreatment process of the flotation products of low grade hard to leach gold ore was made. In accordance with the different properties of flotation products, different time was used. As a result, the amount of ore needing treatment was reduced and pretreatment process both economical and efficient was obtained. The total gold recovery reached 89.1% from this hard to leach gold ore when it was treated by this process.
