| titleOfInvention | Depletion agent and method for copper-nickel smelting slag and/or blowing slag |
| abstract | A depletion agent and method for copper-nickel smelting slag and/or blowing slag. The present invention belongs to the fields of environment, copper-nickel metallurgy, and resource comprehensive utilization. In the method, a novel depletion agent is added to different combinations of copper-nickel smelting slag in a depletion electric furnace, a settling electric furnace, a depletion area, a settling area, a front bed or a slag ladle in a copper-nickel smelting process, so as to promote the growth and sedimentation of copper-nickel-cobalt components and the growth of magnetite, so that not only can the depletion effect of a fire method be improved, but flotation indexes can also be increased, and the depleted slag can be directly used as a raw material for iron-making or a raw material for flotation or magnetic separation or a cement. The novel depletion agent has the advantages of a large specific gravity, reaction controllability, a small addition amount, no need of heating, no need of added equipment, being clean, low costs, a good depletion effect, etc., and is a complex depletion agent. |
