Abstract
MAXIMIZAR EL VALOR DE UN RECURSO DE MENA DE SULFURO MEDIANTE RECHAZO SECUENCIAL DEL DESECHO RESUMEN – OBJETO Y FINALIDAD DE LA INVENCIÓN La invención se refiere a un proceso integrado para recuperar metales valiosos a partir de mena de sulfuro que incluye los pasos de clasificación en bruto 16 y cribado 24/28 de la mena aplastada. La corriente de menas gruesas clasificadas/cribadas se muele y ordena 20 para proporcionar una fracción de gruesos 34 adecuada para flotación de gruesos y una primera fracción de finos 38 adecuada para flotación. La fracción de gruesos adecuada para la flotación de gruesos se somete a una flotación de gruesos 36 para obtener así una ganga 42 y un concentrado intermedio 46. El concentrado intermedio se somete a molienda 48 para proporcionar una segunda fracción de finos adecuada para flotación convencional. La primera fracción de finos y la segunda fracción de finos se someten a una flotación convencional 40 para proporcionar un concentrado y relaves. Este proceso que capitaliza la heterogeneidad natural de los yacimientos de sulfuro y utiliza tecnologías de reducción de clasificación en bruto, cribado y flotación de gruesos en una configuración multietapa novedosa para rechazar la máxima cantidad de ganga de desecho antes de la conminución de finos. Sector: Mecánica.MAXIMIZE THE VALUE OF A SULFIDE LESS RESOURCE BY SEQUENTIAL REJECTION OF THE WASTE SUMMARY - OBJECT AND PURPOSE OF THE INVENTION The invention relates to an integrated process for recovering valuable metals from sulfide ore that includes the rough classification steps 16 and screening 24/28 of the crushed ore. The sorted / screened coarse stream is milled and ordered 20 to provide a thickness fraction 34 suitable for thickness flotation and a first fine fraction 38 suitable for flotation. The thickness fraction suitable for thickness flotation is subjected to a thickness flotation 36 to thereby obtain a bargain 42 and an intermediate concentrate 46. The intermediate concentrate is subjected to grinding 48 to provide a second fine fraction suitable for conventional flotation. The first fraction of fines and the second fraction of fines are subjected to a conventional flotation 40 to provide a concentrate and tailings. This process that capitalizes on the natural heterogeneity of sulphide deposits and uses raw classification reduction, screening and coarse flotation technologies in a novel multi-stage configuration to reject the maximum amount of waste bargain prior to the comminution of fines.
