| Zusammenfassung: | The invention relates to a preparation method of superfine copper oxide powder. In the preparation method, copper ore is used as a raw material, the superfine copper oxide powder is prepared by adopting a spray baking method, and at the same time, the tail gas generated in a spray baking process is absorbed and returned to a production system for recycle. By utilizing the preparation method, the process flow is shortened, the particle size of copper oxide can be controlled by controlling dewatering, baking and crystal regrowth time, and the environmentally-friendly and large-scald industrial production of the superfine copper oxide powder is achieved. |
