Mineralogy and separation experiments were carried out for a low-grade linnaeite ore (0.052%), which belonged to limonite-hematite-pyrite type complex mineral. Under the grinding fineness of 80% -0.074 mm, linnaeite concentrate which contained cobalt grade of 0.51%, recovery rate of 80.99%, sulfur grade of 23.79%, recovery of 88.03% was obtained by closed-circuit processes of one roughing, two scaenging and one cleaning, which used sulfate acid (4500 g/t) and copper sulfate (300 g/t) as activator, so-dium silicate (1000 g/t) and CMC (30 g/t) as inhibitor, ethyl xanthate（100 g/t）and butyl xanthate (100 g/t) as collector, 2# oil (40 g/t) as forther in roughing, no agent in cleaing and first scavenging, used ethyl xan-thate（50 g/t）and butyl xanthate (50 g/t) as collector, 2# oil (20 g/t) as forther in second scavenging.
