Precipitation flotation conditions of zinc which is an essential element for living organisms are determined by using copper-alpha-benzoin-oxime as a new type of carrier. The effects of pH change, amounts of alpha-benzoin-oxime and copper and formation period of related complexes as well as the effect of various other metals are reported. With this method, concentration of zinc was increased 20 times together with 95% recovery. The detection limit for zinc was found to be 1.575 mu g/L by use of flame atomic absorption spectrometry.
