从活性炭吸附金机理和载金炭解吸机理出发,分析了载金炭中铜氰络合离子对贵液的吸附、载金炭解吸、电解过程的影响,并阐述了高铜载金炭中酸法、氰化法和氨法脱铜的机理、优缺点,以及其应用研究进展,为高铜载金炭脱铜提供借鉴.
The paper analyzed the influence of copper cyanide complex ion in the gold loaded carbon on the ad-sorption process,desorption process,electrolytic process based on the mechanism of gold adsorption of activated carbon and loaded carbon desorption. Then the paper elucidated the decoppering mechanism and its advantages and disadvan-tages of high copper content gold loaded carbon by using acid washing,cyanidation and ammonia,and its application research progress.
