The third stage is grinding, where the crushed ore is further processed into fine particles. The fourth stage is flotation, where the fine particles are separated from the rest of the ore using a froth flotation process. The final stage is smelting, where the concentrated copper ore is heated at high temperatures to produce pure copper.
