Abstract
Se provee un procedimiento para el tratamiento de menas que contienen metal precioso refractario, particularmente menas que llevan oro, para reducir la habilidad del carbono orgánico para interferir con la recuperacion del metal precioso. La mena también contiene materiales de sulfuro con los cuales el oro está asociado y a partir de los cuales el oro es difícil de separar. la mena es desmenuzada (104) e un tamaño al cual por lo menos aproximadamente el 80% de la mena es más pequeña que aproximadamente 40 micras en tamaño. La mena desmenuzada después se hace lodo y se somete a oxidacion bajo presion (108) a acondiciones severas de operacion. La temperatura de tratamiento es mayor que aproximadamente 190 degree C. Cuando están presentes minerales de sulfuro, substancialmente todo el sulfuro de azufre debe ser oxidado primero antes de obtener un beneficio significativo del tratamiento del carbono orgánico. Se debe oxidar más del 96% del sulfuro de azufre. La neutralizacion (114) ocurre después del tratamiento de oxidacion para preparar el lodo para cianuracion CIP (118) a partir del cual se recupera entonces el oro (128).
