The application of an experimental X-ray fluorescence analysis characterized by rapid, elemental or surface analysis to the study of adsorption measurement in flotation process is described. The amount of adsorbed chromium was measured by counting the X-ray intensity of Cr-Kα on galena sample surface adsorbed in aqueous solution of potassium dichromate at 25ºC, as a function of adsorption time and concentration of the solutions varied from 0.1to 1, 000mg Cr/l together with pH of the solution. The results obtained by the X-ray fluorescence analysis gave faster and moreprecise determination of adsorbed chromium comparing with those by the conventional spectrophotometric analysis of the solution concentration. It is emphasized that the direct determination of the adsorbate by the X-ray fluorescence analysis may be successfully utilized for the adsorption study of depressor, regardless of any side reaction such as precipitation in the flotation pulp.
