Background
Copper is an irreplaceable important raw material in national economic development and plays a great role in the nonferrous metal industry. The copper mine resource reserves in China are dispersed, and the occupied amount per person is small. The industrial mineral of copper includes Pyritum, chalcopyrite, chalcocite, Paconite, malachite, etc. Currently, there are 280 copper-containing minerals found, and only 16 main copper minerals. Mainly comprises primary copper sulfide ore, secondary copper sulfide ore and copper oxide ore. The types of the copper deposit include five major types, namely a sandstone type, a porphyry type, a volcanic sedimentation type, a layered type and a copper sulfide type. Copper sulphide ore is the main source of copper.
Efficient copper ore collectors are one of the key factors in the flotation of copper. Currently, the research of flotation reagents is developing in two directions: the method is a novel collecting agent which is developed and researched with high efficiency, low toxicity, low price, low consumption and wide raw materials; and secondly, various existing collectors are reasonably matched and combined for use, and the preparation of the high-efficiency copper sulfide ore combined collector with low consumption, selectivity, collecting property and foaming property is a great problem in the current science.
