Sep 18, 2020· As for the ratio of iron-ore to finished iron, as far as we can tell, ancient iron-working was a lot less efficient than modern iron-working. From raw ore to finished goods, the estimates range from 8-16% of the mass of the ore ends up in the finished product. Not quite enough to explain the discrepancy, but still a big gap from modern figures.
Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse. Common iron ore crushers are jaw crusher, cone
