Abstract

QUE COMPRENDE: a) FORMAR UN CONCENTRADO DE SULFURO DE COBRE, LLEVANDO A CABO EL PRE-TRATAMIENTO NECESARIO EN UNA MENA DE SULFURO COMPLEJA; b) ALIMENTAR LA MENA FINA A UNA ETAPA DE SEPARACION-FLOTACION EN DONDE SE EMPLEA UN COLECTOR QUIMICO DE COBRE Y DEPRESIVOS QUIMICOS DE PLOMO, ZINC, NIQUEL Y HIERRO; Y, c) ALIMENTAR UN MINERAL BASICO (DE 0,05% A 5% DE LA CANTIDAD DE MINERAL BRUTO) QUE SE DISUELVE EN LA ETAPA DE PRE-TRATAMIENTO, CON LA MENA DE SULFURO COMPLEJA CON EL FIN DE ELEVAR LA CAPACIDAD REGULADORA DEL pH DE LA MENA. EL MINERAL BASICO ES CARBONATO SODICO, DOLOMITA O MINERAL DE SERPENTINITA, Y ES ANADIDO A LA ETAPA DE TRITURACION O MOLIENDA, EN LA FORMA DE TROZOS O VIRUTAS, O CONDICIONAMIENTO, EN LA FORMA DE POLVO O SUSPENSION, DEL PRE-TRATAMIENTO. EL COLECTOR QUIMICO DE COBRE ES UN COMPUESTO DE TIONOCARBAMATO O UN OXOCOMPUESTO DE AZUFRE (METABISULFITO O DITIONITA); Y EL DEPRESIVO QUIMICO ES UN DEPRESIVO ORGANICO (DEXTRINA). EL POTENCIAL ELECTROQUIMICO DE LA SUSPENSION ES REGULADO A LA ZONA OPTIMA PARA LA SEPARACION DE LOS MINERALES DE COBRE, ANTES DE LA SEPARACION-FLOTACION, POR MEDIO DE AIREACIONWHICH INCLUDES: a) FORMING A COPPER SULFIDE CONCENTRATE, CARRYING OUT THE NECESSARY PRE-TREATMENT ON A COMPLEX SULFIDE ORE; b) FEED THE FINE ORE TO A SEPARATION-FLOTATION STAGE WHERE A CHEMICAL COLLECTOR OF COPPER AND CHEMICAL DEPRESSIVES OF LEAD, ZINC, NICKEL AND IRON IS USED; AND, c) FEED A BASIC MINERAL (FROM 0.05% TO 5% OF THE QUANTITY OF GROSS MINERAL) THAT IS DISSOLVED IN THE PRE-TREATMENT STAGE, WITH THE COMPLEX SULFIDE ORE IN ORDER TO RAISE THE REGULATORY CAPACITY OF THE pH OF THE MENA. BASIC MINERAL IS SODIUM CARBONATE, DOLOMITE OR SERPENTINITE MINERAL, AND IS ADDED TO THE PRE-TREATMENT CRUSHING OR GRINDING STAGE, IN THE FORM OF CHIPS OR CHIPS, OR CONDITIONING, IN THE FORM OF POWDER OR SUSPENSION. THE COPPER CHEMICAL COLLECTOR IS A THIONOCARBAMATE COMPOUND OR A SULFUR OXO COMPOUND (METABISULPHITE OR DITIONITE); AND THE CHEMICAL DEPRESSIVE IS AN ORGANIC DEPRESSIVE (DEXTRIN). THE ELECTROCHEMICAL POTENTIAL OF THE SUSPENSION IS REGULATED TO THE OPTIMAL ZONE FOR THE SEPARATION OF THE COPPER MINERALS, BEFORE THE SEPARATION-FLOTATION, BY MEANS OF AERATION
