| description | The invention discloses a mineral separation method for recovering gold and zinc from polymetallic tailings containing gold, zinc and iron. According to the method, the underflow parameters of the total tailing concentration tank of a mineral separation plant are as follows: the concentration is 25-30%, and the-200-mesh content is greater than or equal to 50%; the underflow of the concentration tank is pumped to a flotation system, a flotation agent comprising 150 g/t of a copper sulfate activator, 30 g/t of a WH-2 activator, 40 g/t of a butyl xanthate collecting agent and 40 g/t of a No.2 oil foaming agent is added, and after stirring mixing is performed, the underflow ore pulp of the concentration tank is fed into a flotation column for roughing, wherein the roughing pH value is 7.5, and the roughing flotation time is 6 minutes; the roughing underflow is fed into another flotation column for primary scavenging, wherein the scavenging flotation time is 4 minutes, and a scavenging agent comprises 30 g/t of a |
