Before the risk elimination question can be asked, it is important to understand that repairs, maintenance, relocating crushing spreads and unplugging crushers are major causes of injuries and death. Very few are hurt sitting in a centralized control tower or loader cab.
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. Secondary crushing and screening can result in further classification and grading of iron ore.
