In the manufacture of iron from iron ore, what is the name for the process of obtaining small particles of iron ore so that they are easily reduced?

The majority of iron ore used in manufacturing of iron is extracted from the ground by mining. The iron ore produced from the mine will likely be quite large. These iron ore rocks need to be broken up somehow to form smaller particles. This is so when they’re added to the blast furnace, they react quickly. The process whereby these rocks are converted into small particles serves to increase their surface area.

So the question is, what is the name for the process of obtaining these small particles? The large rocks are fed into a hopper, where they are ground into smaller particles. The type of this machine is a crushing machine. So the name of the process for obtaining small particles of iron ore so that they can easily be reduced is crushing.
