Trace And Minor Elements

Laterites and bauxites are residual products derived from a wide variety of rocks by intensive chemical weathering under strongly oxidizing and leaching conditions. Generally the main constituents of these residues are Fe, Al and Ti present in form of hydroxides and/or oxides. The content of silica depends on the thoroughness of the leaching process. The behaviour of trace and minor elements as Ga, Zn, Cu, Ni, Mn and Cr during the laterite/bauxite formation is not yet well established. Precise and accurate analyses of these elements are a prerequisite for such investigations. In this paper the standard addition method is presented and the results are compared with those obtained by calibration standardization. The accuracy and the precision of the methods as well as the distinction limit and the limit of detection for each element are given.
