Solved An iron ore sample is concentrated using a gravity

Question: An iron ore sample is concentrated using a gravity concentrator and a magnetic separator.The feed is initially fed to the gravity concentrator, and the tailings from the gravity concentrator are fed to a re-grind ball mill and the mill product is fed to a magnetic separator.The concentrate streams from the gravity concentrator and the magnetic …

A Brief History of Mining in Michigan's Marquette and …

By today's standards, nearly all of the pre-World War II iron ore produced would be considered "high grade." Ore was shipped directly from the mines to the iron furnaces. From the 1880s on, an increasing number of concentrators began operation. They typically used gravity separation methods (crushing, screening, washing, and drying) to
