Abstract: As a kind of important copper oxide ore with high copper content in refractory copper ores,the high efficiency utilization of chrysocolla can alleviate the contradiction between supply and demand of copper resources in China.This paper briefly introduces the characteristics of three aspects of the distribution,structure and surface properties of chrysocolla,analyzes the flotation research methods and present situation of chrysocolla,and summarizes the reasons for the difficulty of chrysocolla in the flotation.It pointed out that flotation by copper chelating agent is the most promising method for the development of chrysocolla.
