The invention relates to the technical field of mineral separation, and particularly discloses a cobalt-rich crust separation method and application. According to the cobalt-rich crust separation method, separation is conducted in a reverse flotation mode, no pH value regulator is added during roughing, starch serves as an inhibitor, and oleic acid and tall oil fatty acid are compounded to serve as a collecting agent. The method is high in adaptability, high in valuable element recovery rate, simple in reagent regime, low in medicament cost and easy to control in production. 本发明涉及选矿技术领域，具体公开了一种富钴结壳的分选方法及应用。本发明的富钴结壳的分选方法，采用反浮选方式进行分选，在粗选时不添加pH值调整剂，以淀粉作为抑制剂，油酸与妥尔油脂肪酸复配作为捕收剂。本发明的方法适应性强、有价元素回收率高、药剂制度简单、药剂成本低且生产易操控。
