iron ore separation process

iron ore separation process

Iron ore - WikipediaThe waste comes in two forms, non-ore bedrock in the mine (overburden or interburden locally known as mullock), and unwanted minerals which are an intrinsic part of the ore rock itself (gangue). The mullock is mined and piled in waste dumps, and the gangue is separated during the beneficiation process and is removed.iron ore separation process,Iron Ore - Mineral TechnologiesProcess Flowsheets. High grade concentrates and high recovery of iron ore can be achieved using effective feed preparation systems (typically controlled crushing, screening, milling, classification and slimes removal) in combination with cost effective, efficient metallurgical separation. Hard rock hematite deposits often.
