Abstract

Because of the particularity of the cyanide liquid,the frequently-used analysis methods can’t achieve an ideal recovery rate of gold and silver.The lower analysis precision of the methods affected the controlling of the process indicators.At the same time,Alkaline cyanide liquid caused a severe corrosion for the instrument, which reduced the equipment life and stability and increased the operating costs.By acidified the high-grade liquid cyanide,using acetate fiber which soaked by organic solvents enriched gold and silver in the solution at the media of a certain concentration aqua regia,and then desorbed them using 20 g/L of thiourea solution in a water bath heating.Finally,the recovery rate of the gold and silver were analyzed by ICP-AES in thiourea solutions which achieved 98.5%~100.5%.The detection limit of the method is 0.0021 for gold and 0.0030 for silver.
