Cleveland-Cliffs Inc. - Operations - Steelmaking - Iron Ore

Northshore operations consist of an open pit truck and shovel mine where two stages of crushing occur before the ore is transported along a wholly owned rail line to the plant site in Silver Bay. At the plant site, two additional stages of crushing occur before the ore is sent to the concentrator. The concentrator utilizes rod mills and magnetic separation to produce a magnetite concentrate ...

iron ore crusher operation

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a high-grade concentrate with very low levels of impurities.

Baffinland: Mary River Mine

What makes Baffinland's operations different than many other mines is that we crush and screen the ore on site, and then ship it directly to markets – no concentrating or processing is needed, and therefore no tailings are produced. History. In July 1962, Mary River’s high-grade iron ore – now known as Deposit No. 1 – was first noted by Murray Watts and Ron Sheardown. The two pilots ...

Mineral processing - Wikipedia

Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding ...
