| description | The invention discloses a method for recovering gold from high arsenic gold tailings. The method comprises the following steps: (1) performing magnetic separation; (2) performing floatation on magnetic tailings; (3) performing rough concentration on sulfur tailings; (4) performing sulfur roughing foam blank selection; and (5) performing strong magnetic separation on arsenic concentrate. The methodhas the following beneficial effects: by adoption of step-by-step magnetic separation and step-by-step floatation combined process flow, particularly strong magnetic separation with magnetic field intensity up to 8000 Gs to 8500 Gs on the arsenic concentrate, the problems in the traditional process that arsenic mineral obtained from the gold tailings has low gold grade and gold is difficult to enrich in the subsequent operation are solved, and the level of the gold in the arsenic mineral is significantly improved. The method has important significance in increasing enterprise economic benefitand social benefit.
