Summary

A rapid two-part procedure was described for the determination of the elements Al, Fe, Ti, Cr, Ni, V, Mn, Cu, Ag, Au, Ga, Si, Ca, Mg and K in bauxite samples from central Greece. After an NaOH decomposition and an HCl pressure decomposition as well as an aqua regia decomposition carried out in addition, an optimization of the measuring program in time was achieved by constant alternation of atomic absorption spectrometry and atomic flame emission. The elements Ga and Au were measured directly in their extracts using AAS.
