Abstract
<p>La invención se relaciona con la rama hidrometalúrgica extractiva de minerales lateríticos con el proceso de lixiviación ácida a presión, donde se hace referencia al mejoramiento de la densificación y compactación de las pulpas crudas de laterita, valoradas de mala sedimentación con una velocidad empírica de sedimentación menor de 135 mm/h.</p> <p>El procedimiento permite mejorar la densificación y compactación de las pulpas crudas de laterita caracterizada por someter el mineral a un tratamiento de oreo controlado lo que permite la pérdida de humedad entre 50-70 % con respecto a la humedad inicial del mineral, al eliminar el agua superficial, para acelerar la formación de óxidos en la superficie del mineral, posteriormente se prepara una pulpa entre 20-25% de sólidos y se deja sedimentar. Alternativamente se añaden sales metálicas Fe, Al y sulfato, entre otras en medio ácido, lo que le confiere al mineral buena viscosidad y capacidad de bombeo. </p><p> The invention relates to the extractive hydrometallurgical branch of lateritic minerals with the process of acid pressure leaching, where reference is made to the improvement of densification and compaction of raw laterite pulps, rated for poor sedimentation with an empirical velocity of sedimentation less than 135 mm / h. </p> <p> The procedure allows to improve the densification and compaction of the raw pulps of laterite characterized by subjecting the mineral to a controlled oreo treatment which allows moisture loss between 50 -70% with respect to the initial moisture of the mineral, by removing surface water, to accelerate the formation of oxides on the surface of the mineral, subsequently a pulp is prepared between 20-25% solids and allowed to settle. Alternatively, Fe, Al and sulfate metal salts are added, among others in an acid medium, which gives the mineral good viscosity and pumping capacity. </p>
