FIELD: mineral dressing. SUBSTANCE: invention concerns mainly ledge sulfide ore-containing ores with irregular polydisperse embeddings. Line includes, in the process direction, interconnected by transportation means: first-stage disintegration module, first-stage concentration module, second-stage disintegration module, second-stage concentration module, third-stage concentration module, and concentrate finishing module. The second- stage concentration module is constructed as monochamber for rapid coarse-grained flotation and centrifugal concentrator, its inlet being connected to monochamber tails' outlet. EFFECT: enhanced efficiency of process. 1 dwg
