Comprehensive Utilization Status of Low-grade and Refractory Zinc Oxide Ores

It is difficult to handle zinc oxide ores due to its kinds of zinc mineral type in zinc ore, complex mineral structure, fine—grained dissemination, high content of ore slime, high content of soluble salt. Based on the research of lots of correlative literature, this article provides an overview of comprehensive utilization status of low grade and refractory zinc oxide ores on behalf of flotation, pyrometallurgy, hydrometallurgy, new process and so on.
