Test Research on Comprehesive Recovery of Polymetallic Refractory Molybdenum Ore

Yang Jinlin Zhang Hongmei He Tingshu Xie Jianhong (Institute of Material Science and Engineering, Xi’an University of Architecture and Technology)  
The polymetallic refractory molybdenum ore is seriously oxidized. There is a high mutual mineral content and a close inlaid relation in the main minerals. Therefore, the bulk flotation process was used and the bulk concentrates were obtained. The molybdenum content in the concentrates was 4.21%, gold content was 48.86 g/t and silver content was 84.80 g/t. It was difficult to separate the molybdenum from the bulk concentrates by the conventional physical dressing method, therefore, the chemical method was adopted. The final leaching rate of the molybdenum was 86.6% and the molybdenum was effectively separated from other valuable metals.
