| Abstract: | An ore-dressing plant uses flotation process to treat arsenic and carbonaceous micro-fine particle dissemination refractory gold ores,but in recent years,the concentration ratio is low and the gold recovery index is not satis fying.To improve flotation performance,the ore-dressing process flowsheet is investigated,based on which process flowsheet renovation and reagent regime optimization are implemented.By renovating middlings treatment and recycling carrier process and adding modifiers,the concentration ratio,gold grade in gold concentrates and gold recovery rate are improved,obtaining good economic profits:net profits 1196000 yuan/a,and at the same time saving 2.7 million yuan/a for downstream smelting enterprises. |
