| Abstract: |
| The cyanide tailings produced in a gold mine cyanide workshop in Qinghai contain valuable elements such as gold, silver, lead and zinc, of which gold grade is 2.68g/t, silver grade is 28.76g/t, lead grade is about 1.27%, zinc The grade is about 1.05%, which has a high recycling value. Using the flotation process, in the high cyanide and high alkalinity medium, after the scrubbing of the cyanide tailings, destroying the surface of the oxidized mineral of the metal mineral, a rough selection, two sweeps, two selections are used. The flotation process finally obtained a lead-zinc grade of 33.45%, a gold grade of 16.26g/t, a silver grade of 332.84g/t of flotation concentrate, and the arsenic in the cyanide tailings was inhibited, and the arsenic in the concentrate The grade is only 0.35%, which realizes the comprehensive recovery of resources |
