Abstract

The objective of the study is separating the gold (I) and its coexistence base metals from cyanide leaching solution by homemade weak and strong alkaline anion exchange fiber inseries, by using their selectivity and the adsorption capacity, respectively. The optimal conditions of the adsorption/elution are as follows: for WAAEF, the suitable flow rate of the adsorption is 61.40 BV/h, and the loading density is 0.262 g/cm³; for SAAEF, the suitable flow rate of the adsorption is 872.2BV/h, and the loading density is 0.202 g/cm³. A mixture of 2.5 mol/L NH₄SCN with 0.1 mol/L NaOH is chosen as the gold (I) eluent, and the eluention flow rate is 96.90 BV/h. The conclusion is that the homemade fibers could be used inseries to extract the gold (I) from cyanide leaching solution.
