The invention discloses a novel technology for comprehensively recovering copper and cobalt from cobalt-copper concentrate, comprising the following steps of: mixing copper sulphide concentrate and flux into copper oxide concentrate to carry out electric smelting to obtain cobalt-containing crude copper and low-cobalt slag by one step, introducing rich oxygen to the cobalt-containing crude copper for blowing to obtain crude copper and high-cobalt slag, carrying out electrorefining on crude copper, adding cobalt slag into a reducing agent to carry out reduction smelting to obtain copper-cobalt alloy and furnace slag. According to the technology, the cobalt-containing high-grade copper sulphide concentrate and copper oxide concentrate can be treated simultaneously, the crude copper can be produced for once, the novel technology is free from the generation of ice copper in the technical process, a process of blowing ice copper can be eliminated, a smelting process by a copper fire process can be simplified, the energy consumption of a fire-process copper smelting technology can be reduced, and the cobalt in the copper concentrate can be recycled at one step due to the reduction of the cobalt slag.
