1. Process: The crushed ore is further reduced to a fine powder to release nickel minerals from the gangue. Grinding ensures the ore particles are of uniform size, which is crucial for downstream processes. 2. Key Equipment: Ball Mills: For wet or dry grinding of ore. Rod Mills: For more precise grinding needs.

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
