Abstract
DONDE EL CONCENTRADO ES LIXIVIADO EN UNA SOLUCION ACUOSA DE CLORURO DE COBRE Y CLORURO ALCALINO QUE CONTIENE ACIDO CLORHIDRICO Y EL AZUFRE PERMANECE EN EL RESIDUO FORMADO EN LA LIXIVIACION. EL POTENCIAL REDOX DE LA LIXIVIACION SE REGULA MEDIANTE UN AGENTE OXIDANTE AL RANGO DE 400-600 mV CON REFERENCIA A UN ELECTRODO DE Ag/AgCl Y EL pH SE AJUSTA EN EL RANGO DE 0.2-1, DESPUES DE LO CUAL EL COBRE, EL FIERRO Y EL ARSENICO EN LOS MINERALES CON ARSENICO SE DISUELVEN Y LOS METALES DEL GRUPO DEL ORO Y/O PLATINO UNIDOS A ESTOS MINERALES SE LIBERAN; LA PIRITA Y LOS METALES DEL GRUPO DEL ORO Y/O PLATINO QUE ELLA CONTIENE ASI COMO TAMBIEN LOS METALES DEL GRUPO ORO Y/O PLATINO LIBRES Y EL AZUFRE PERMANECEN EN EL RESIDUO DE LA LIXIVIACION. LA SOLUCION DE CLORURO CUPRICO QUE CONTIENE FIERRO Y ARSENICO SE NEUTRALIZA PARA PRECIPITAR ESTOS, DESPUES DE LO CUAL LA SOLUCION DE CLORURO CUPRICO LIBRE DE FIERRO Y DE ARSENICO NEUTRALIZADA SE LLEVA A UNA ETAPA DE EXTRACCION LIQUIDO-LIQUIDO, EN DONDE EL COBRE ES RECUPERADO EN UNA SOLUCION ACUOSA DE ACIDO SULFURICO Y ES LLEVADO A LA ELECTRO REFINACION PARA RECUPERAR COBRE ELEMENTAL Y EL REFINADO DE LA EXTRACCION LIQUIDO-LIQUIDO ES LLEVADO DE NUEVO A LA LIXIVIACION DEL CONCENTRADO. ADEMAS, EL RESIDUO DE LA LIXIVIACION SE SOMETE A UNA FLOTACION DE AZUFRE
