为了给某低品位铜钴镍矿石的合理开发利用提供依据，针对该矿石性质，采用全优先浮选工艺流程。浮铜采用CMC纤维素分散并抑制矿泥、漂白粉抑制钴镍矿物及磁黄铁矿、选择性较好的甲基硫氨酯为铜捕收剂、铜粗精矿再磨等工艺；浮钴镍采用碳酸钠调整矿浆p H值、氟硅酸钠活化钴镍矿物、丁基黄药＋C－125为钴镍矿物捕收剂等工艺实验；实验获得含铜18．32％，铜回收率64．27％的铜精矿；含钴0．577％，含镍1．68％，钴回收率54.35％，镍回收率55．28％的钴精矿。此外，还得到含硫38．68％，硫回收率69．90％的硫精矿。
為瞭給某低品位銅鈷鎳礦石的閤理開髮利用提供依據，針對該礦石性質，採用全優先浮選工藝流程。浮銅採用CMC纖維素分散併抑製礦泥、漂白粉抑製鈷鎳礦物及磁黃鐵礦、選擇性較好的甲基硫氨酯為銅捕收劑、銅粗精礦再磨等工藝；浮鈷鎳採用碳痠鈉調整礦漿p H值、氟硅痠鈉活化鈷鎳礦物、丁基黃藥＋C－125為鈷鎳礦物捕收劑等工藝實驗；實驗穫得含銅18．32％，銅迴收率64．27％的銅精礦；含鈷0．577％，含鎳1．68％，鈷迴收率54.35％，鎳迴收率55．28％的鈷精礦。此外，還得到含硫38．68％，硫迴收率69．90％的硫精礦。
