Abstract: The storage of low-grade copper oxide ore in our country is great，but the easy-processing and high-grade copper ore resources are relatively poor.In order to solve the problem of copper oxide ore resources self-sufficiency，enhance the beneficiation and metallurgy research of low grade copper oxide resources is really essential.In order to let the mineral processing workers fully understand the current development and utilization situation of low-grade copper oxide ore resources，promoting the progress of low-grade copper resources beneficiation and metallurgy technology，research situation and progress of low-grade copper oxide ore beneficiation technology was introduced mainly from conventional leaching，bacterial leaching，dressing-metallurgy combination technology.In addition，conventional leaching，bacterial leaching and dressing-metallurgy combination technology are important methods for resolving the low-grade refractory copper oxide ore resources development and utilization.

Key words: Copper oxide ore, Acid leaching, Bacterial leaching, Beneficiation-metallurgy technology
