英文摘要：

A new technology of low-temperature reduction and grain growth of copper slag was developed based on the characteristic of copper slag. With low reduction temperature and elimination of the melting and separation, this technology is a new method for an efficient utilization of resources and energy. The new technology has the advantages of low-energy consumption, flexible to smelting, environment-friendliness, low investment and cost.
