Sulphide flotation of actual oxide copper minerals (such as malachite, azurite) is not possible with sulfhydryl mineral flotation collectors and either other oxide type collectors are required or alter-native mineral beneficiation routes must be considered.

However, most copper oxide ore have the problems such as high slime, poor floatability, complex ore property and low flotation recovery, so it is of great significance in beneficiation of copper oxide ore to develop an efficient collector for copper oxide ore especially for malachite [24].
