1. Crushing and grinding: The raw ore is initially crushed by crushing equipment, and then finely crushed by grinding equipment to achieve a particle size suitable for flotation.
2. Mixing and stirring: The ground ore is mixed with flotation agents, foaming agents, etc., and fully stirred in a stirring tank so that the flotation agent is fully in contact with the ore.
3. Bubble blowing: The mixed and stirred ore slurry is passed through a flotation machine, and the air is blown into the foam so that the copper-containing minerals adhere to the foam, thereby separating them from other impurity minerals.
4. Separation: The copper-containing minerals and impurity minerals in the foam are separated, usually by a scraper separation device in a flotation machine.
5. Degassing: The separated copper-containing mineral foam is degassed to remove the moisture and flotation agent, and a dry copper concentrate is obtained.
6. Concentrate treatment: The copper concentrate is further processed, usually including leaching, smelting, and other steps, and finally pure copper metal is obtained.
