【Abstract】 Practice of removing impurity using acidification-oxidation process from deficient liquid of cyanide plant is introduced briefly in the paper. Using the process, the content of copper, cyanide, lead and zinc in the deficient liquid can be reduced to less than 1.5, 0.5, 1.0 and 1.0 mg/L, so the deficient liquid can be used circularly. In addition, the cyanide in the deficient liquid can be used effectively, which brings the environmental, social and economic benefit favorably.更多还原
