Abstract: A method for determination of chlorine in zinc concentrates by neutral leachingout ercuric thiocyanate mmonium ferric sulfate spectrophotometry is proposed in this paper. The recovery of the method is 95.62％～106.25％ with the precision of 1.99%～7.37％RSD (n=7). Advantages of high accuracy, wide determination range (0.02％～4.0％), simple operation and rapidity are also provided by the method.
