Flotation separation method of high-sulfur and high-arsenic gold ore

The invention discloses a flotation separation method of high-sulfur and high-arsenic gold ore, and belongs to the technical field of mineral processing. The flotation separation method comprises thesteps of (1) grinding raw ore to the preset fineness; (2) performing shaking table sorting treatment on ground products so as to recycle natural and native gold dissociated from the raw ore; and (3) merging shaking table tailings, then performing flotation operation, adding water glass and macromolecular agents containing -OH and -O- groups as a combined inhibitor, adding copper sulfate as an activating agent, fully mixing, then adding a collecting agent and a foaming agent, and performing flotation separation so as to obtain gold concentrates. According to the flotation separation method of the high-sulfur and high-arsenic gold ore, gold is recycled by adopting a reselection-flotation combined technological process, so that the recycling of gold is strengthened; the macromolecular agentscontaining the -OH and -O-
