Abstract
<p>La invención proporciona un procedimiento que permite mejorar la densificación y compactación de las pulpas crudas de laterita, en el proceso de lixiviación ácida a presión, mediante un tratamiento físico químico (oreo controlado) al mineral, para eliminar el agua superficial que acelera la formación de óxidos en la superficie deI mineral, con la deposición de hidróxidos los cuales disminuyen la agregación entre las partículas. El procedimiento propuesto mejora la sedimentación y compactación de la pulpa. Con el mineral tratado se prepara una pulpa de 20-25 porciento de sólido la cual se deja sedimentar, alternativamente se añaden sales metálicas de Fe, Al y sulfato, entre otras en medio ácido, lo que confiere al mineral buena viscosidad y capacidad de bombeo.</p><p> The invention provides a method that improves the densification and compaction of the raw pulps of laterite, in the process of acidic leaching under pressure, by means of a chemical physical treatment (controlled oreo) to the mineral, to eliminate the surface water that accelerates the formation of oxides on the surface of the mineral, with the deposition of hydroxides which decrease the aggregation between the particles. The proposed procedure improves sedimentation and compaction of the pulp. With the treated mineral a pulp of 20-25 percent of solid is prepared which is allowed to settle, alternatively metal salts of Fe, Al and sulfate are added, among others in acidic medium, which gives the mineral good viscosity and pumping capacity . </p>
