The invention discloses a technology for efficiently and selectively separating zinc in zinc sulfide concentrate. The technology includes the steps that the zinc sulfide concentrate serves as a raw material and is wetly ground, then the wetly-ground concentrate and sulfuric acid or waste electrolyte are mixed into a slurry and poured into a high-pressure kettle for leaching, an adjusting agent A is added, pure oxygen is led in, the proper final acidity is controlled, and most Fe and most As in the zinc sulfide concentrate enter slag in the hematite mode, the iron vitriol mode and the ferric arsenate salt mode. Leached liquid is subjected to acidity regulation to be directly electrolyzed in a rotational flow mode, zinc in the leached liquid is extracted, and an electric zinc product meeting the national standard can be obtained. According to the technology, the traditional purification working procedure is omitted, the technological process and a device are simplified, the technology is simple, operation is easy and convenient, energy consumption is reduced, the leaching rate and the recovery rate of the zinc are increased, resources are saved accordingly, and cost is reduced.
