Abstract: A cobalt nickel arsenic ore in Africa contains nickel 3.05% and cobalt 0.23%, on the basis of ore technology mineralogy research compeletion, test principle process of jigging gravity separation-flotation was drafted pointed, experimental study indicated, through jigging pre-discarding tailings, one time roughing three times scavenging twice regrade, middling order return flotation, this nickel cobalt ore could got the nickel cobalt comprehensive concentrate with nickel grade 26.44%,cobalt grade 154%,nickel recovery rate 88.53%,cobalt recovery rate 75.87%.

Key words: Cobalt nickel arsenic ore, Jigging, Flotation
