In this study, the potential of boron in Turkey, commercial most-used compounds of boron and their production trends according to years and analyses of boronic samples obtained different sources were investigated. Besides classic analysis technics, X-ray fluorescence spectrometric (XRF) and flame photometric methods were carried out for boronic samples. Chemical compositions of original and concentrated samples were studied with respect to the contents of B, Li, Ca, Al, Fe, Mg, S, As, Si, Sr and Na. The leaching of boric acid with CO2-saturated water from boron minerals was also investigated. (C) 1998 Elsevier Science B.V. All rights reserved.
