Electrochemical Trace Analysis of Sphalerite in Ore for Its Metal Content

Sphalerite (zinc blende), is a most common zinc ore ((Zn,Fe)S) it is a mineral that is the chief ore of zinc The composition of sphalerite are 67% Zn, 33% S with varying amounts of iron and manganese, and other elements. a sphalerite ore sample obtained from Rajpur Dariba, Udaipur district, Rajasthan India. Element the method of standard addition was used for quantitative analysis. The DC and DP Polarograms of the sample saluting (Fig 3 a, b )showed well defined waves / peaks with E½ / Ep values = -0.08/-0.09, -0.24/-0.28, -0.40/-0.42,-0.49/-0.50,-1.14/1.16,-1.2/1.3, -1.32/1.28,-1.56/-1.57,-2.36/2.38, V vs. SCE in DCP/DPP mode Indicating the presence of Au, Cu , Pb, Cd, ,Zn ,Mn, Fe,Ga, Mg, Finally the obtained polarography analysis results on sphalerite ore sample and their comparison with atomic absorption spectroscopy Method.
