Abstract
The present invention relates to the field of ore smelting technology, and particularly provides a method and system for comprehensive recovery and utilization of copper-nickel sulfide ore. Under normal pressure, the method can be used to directly leach copper-nickel sulfide ore concentrate or low-grade nickel matte obtained by matte smelting of copper-nickel sulfide ore. In the leaching process, the leaching rate of nickel, cobalt and iron is up to 99% or more, and copper is hardly leached, whereby the deep separation of copper from elements such as nickel and cobalt is directly realized, and the huge system for copper-nickel separation in the conventional process is omitted. Moreover, noble metals are not leached, and almost all of them remain in the leaching slag with copper, so the destiny is simple.
