| description | The invention discloses a bridge traction induced beneficiation method for copper-nickel sulfide ore, which mainly comprises the following steps: preparing strong floatability concentrate as a bridge traction medium in the existing grading process, treating the strong floatability concentrate, and respectively adding the strong floatability concentrate into the grading process to optimize the grading index. Aiming at the problems of flotation recovery of micro-fine particle minerals in the field of non-ferrous metal mineral separation, poor separation selectivity of non-ferrous metal micro-fine particle minerals in the existing conventional flotation and the like, strong floatable concentrates are added in two-stage roughing, two-stage primary concentration and two-stage fine scavenging, so that the copper or nickel ore flotation recovery rate of each operation stage is remarkably improved; according to the method, high-floatability concentrate is adopted to bridge and pull high-content fine-fraction minerals |
