The invention discloses a method for extracting zinc cleanly. The method comprises the steps that 1, a zinc raw material reacts with a leaching agent, and leachate containing zinc is obtained; 2, the leachate is extracted by the adoption of an organic phase, zinc is directly extracted, and zinc extracted liquid residue is obtained; 3, nickel cobalt copper is extracted from the zinc extracted liquid residue by the adoption of the organic phase, reverse extraction is carried out, and corresponding nickel cobalt copper salt and extracted liquid residue are obtained; and 4, the extracted liquid residue returns to be leached. According to the method, in the zinc, nickel, cobalt and copper extracting process, the organic phase does not need to be saponified, sodium or ammonium is prevented from entering the extracted liquid residue and causing pollution, thus, material consumption in the zinc smelting process is reduced, and cost is reduced. In the extraction process, regeneration of the leaching agent is achieved, the extracted liquid residue can directly return to be leached, and zero emission of leached system water can be achieved.
