Sulfidation reconstruction methods for improving the floatability of copper oxide minerals: A review
Copper oxide minerals are important raw materials for copper production, mainly including malachite, chrysocolla and cuprite. Flotation is the main method to extract copper from copper oxide minerals. However, the high surface polarity of copper oxide minerals restricts the flotation process. In this paper, the mineralogical characteristics of copper oxide minerals are described briefly. The treatment methods of sulfidation including surface sulfidation, mechanochemical sulfidation and sulfidation roasting are summarized to improve the floatability of copper oxide minerals. In particular, this paper analyses the sulfidation reaction mechanism. An efficient way to promote flotation recovery is to form a sulfide film on the mineral surface. The research direction for further utilization of copper oxide minerals is prospected.
期刊介绍:
The purpose of the journal is to provide for the rapid publication of topical papers featuring the latest developments in the allied fields of mineral processing and extractive metallurgy. Its wide ranging coverage of research and practical (operating) topics includes physical separation methods, such as comminution, flotation concentration and dewatering, chemical methods such as bio-, hydro-, and electro-metallurgy, analytical techniques, process control, simulation and instrumentation, and mineralogical aspects of processing. Environmental issues, particularly those pertaining to sustainable development, will also be strongly covered.
