Abstract

Un procedimiento para la extracción de metal a partir de una amena o concentrado que contiene valores niquel y/o cobalto y otros metales, comprende someter la mena o concentrado a lixiviación ácida bajo presión a pH 2, para obtener un licor conteniendo valores de niquel y/o cobalto, sometiendo el licor a una primera etapa de precipitación a un pH de alrededor de 5 a 6 para producir un sólido que no contiene metales de niquel ni cobalto y una solución resultante que contienen valores de niquel y/o cobalto y sometiendo la solución resultante a una segunda etapa de precipitación a un pH de aproximadamente 7 a 8, para producir un sólido conteniendo niquel y/o cobalto.A procedure for the extraction of metal from an amine or concentrate that contains nickel and / or cobalt and other metals, comprises subjecting the ore or concentrate to acid leaching under pressure at pH 2, to obtain a liquor containing nickel and / or cobalt, subjecting the liquor to a first precipitation stage at a pH of around 5 to 6 to produce a solid that does not contain nickel or cobalt metals and a resulting solution that contains nickel and / or cobalt values and subjecting the resulting solution to a second precipitation stage at a pH of about 7 to 8, to produce a solid containing nickel and / or cobalt.
