Abstract

The invention discloses a gold storage yard synchronous gold leaching and carbon removal leaching aid. The gold storage yard synchronous gold leaching and carbon removal leaching aid comprises a core carbon removal leaching aid component and a functional auxiliary component, the core carbon-removing and leaching-assisting component is sodium cyanurate; the sodium cyanurate and the functional auxiliary component have a synergistic effect, and are used for inhibiting the adsorption of a gold-cyanogen complex by virtue of selective combination and complexation with adsorption sites on the surface of a carbonaceous substance in a cyaniding gold leaching process, so that carbon removal and assisted leaching are synchronously realized; the method has the advantages of efficient and synchronous carbon removal, low toxicity, safety and complete compatibility with a cyaniding gold leaching process.
