DETERMINATION OF COPPER IN COPPER ORES USING VARIOUS ANALYTICAL TECHNIQUES

Abstract

Two different geological copper ore materials comprising malachite and covellite were analyzed for the percentage of copper using three different analytical techniques, namely, colorimetry, titrimetry and gravimetry respectively. The analysis reveals that the mean percentages of copper in malachite sample using colorimetric, titrimetric and gravimetric techniques are 63.50, 63.50 and 61.63 respectively, while the average percent ages 0 f copper in t he cove 11 it e are samp 1 e were found to be 42.33, 42,86 and 39.51% respectively. The techniques could be used for the routine determination of the percentage of copper in copper ores.
