Resumen
This article describes the cementation process of leached solutions from copper sulphide ores being and without being toasted. With favorable results in this study, we get the pattern for the feasibility of moving from the classical technology of concentration to the technology of cementation of copper sulfide minerals containing silver and gold. Simulation steps have been performed considering the different variables involved in the process such as time, agitation, solution concentration, pH and others. A kinetic model of copper cementation from PLS solutions purified by Solvent Extraction (SX) has been developed and it has the following form: C = 6.08 exp (- 0.03 t) Recoveries were obtained greater than 90% copper, which gives the possibility to improve the costs of national ores and con- centrates, as well as to open a favorable scenario for new national metallurgical projects. El presente artículo trata de describir la cementación de soluciones lixiviadas de minerales sulfurados de cobre sin tostar y tostados, obteniéndose resultados favorables lo que nos dan la pauta para la factibilidad de pasar de la clasica tecnología de concentración a la tecnología de cementación de minerales sulfurados de cobre con buenos tenores de plata y oro. Se ha procedido a realizar simulaciones del proceso considerando las variables involucradas en el proceso, tales como tiempo, agitación, concentración de soluciones, pH entre otros. El Modelo Cinético de Cementación del Cobre a partir de soluciones PLS purificadas por Extracción por Solventes (SX) encontrado tiene la siguiente configuración: C = 6,08 exp( - 0,03t) Se han obtenido recuperaciones mayores del 90% de cobre, lo cual nos indica la posibilidad de mejorar los costos de los minerales y concentrados nacionales y abrir un escenario favorable para otros proyectos metalúrgicos nacionales.
