Mattenella Ingeniería borates isoelectric point Industrial minerals point of zero charges quantitative Rietveld analysis The increasing range of borate uses, mainly in the ceramic frit market, led borate producers to improve competitivenessthrough concentration and/or purification steps in the mill circuit as well as in the characterization of high content B2O3minerals.Minerals coming from Sijes, Salta Province, Argentina, mainly identified as colemanite and hydroboracite, with 50.84%and 50.54% B2O3 respectively, are potentially interesting from an industrial point of view. The desliming purificationtechnique in hydrocyclones used to upgrade B2O3 and downgrade undesirable impurities to the borate market (Rietveldmethod) mainly iron oxides, chlorides and sulphates) not only eliminates slimes but it also generates pores, through adecrease of the specific surface of the particles. Two samples under different purification steps were analyzed: deslimedand without desliming. The chemical and mineralogical analyses of both samples indicate a decreasing percentage ofcolemanite, smectite and illite in the deslimed sample with a small increase of hydroboracite. The parameters of surfaceelectric charge (PZC and IEP) match the observations made with the electronic microscopy, reveal mineral associationsonly in the sample without desliming. 2007 artículo científico 0718-3291 https://www.redalyc.org/articulo.oa?id=77215105 en http://www.redalyc.org/revista.oa?id=772 Ingeniare.
