Question: 1a, The mills used to crush iron ore are lined with a high carbon steel. During the crushing process, the steel will experience fast loading rates (high strain rates) from the ipact of the ore. As the loading rates of these impact events increases, the steel is more likely to fail by: Group of answer choices fatigue ductile fracture ...

But How is Iron Ore Mined? Iron ore mining is relatively simple compared to other minerals and metals that require underground tunnels and complex chemical-drive processes, like gold. Iron ore is generally sourced from open pits on the planet's surface and typically requires only crushing before it is ready for the smelter.
