Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock.

This step involves breaking up the iron ore to obtain an F 80 grind size before it can be ground. Once the ore has been crushed, it is diverted to a stockpile. The aim of this step is to ensure a smooth crushing process and minimise downtime in the event of a breakdown or to allow planned maintenance in the crushing system, without stopping the ...
