| dc.description | La ultraflotación se utiliza para remover impurezas ultrafinas utilizando un mineral auxiliar llamado portador, cuyo sistema se fundamenta en las diferencias de mojabilidad de los sólidos. Se presenta el análisis aplicado a la calcita (CaCO3), utilizada como portador en el sistema de ultraflotación de anatasa (TiO2) a partir de caolines. Se aplicó la técnica “mojabilidad de capas delgadas”
para determinar el ángulo de contacto en medio acuoso y su variación por efecto de la adición del colector. A partir de estos resultados se determinó la tensión superficial y sus componentes para analizar los cambios fisicoquímicos superficiales experimentados por el mineral. | |

This appears the analysis applied to the calcite (CaCO3). This is used like carrier in the ultraflotation system of anatase (TiO2) from kaolins. The technical “wetabillity of thin layers” was applied to determine the contact angle
in aqueous media and its variation by effect of the addition of collector. The superficial tension and its components were determined from these results to analyze the superficial physico-chemical changes experienced by the mineral | |
