Iron ore mining and dressing

Iron Ore: Price Fundamentals Analyst: Dr Trent Allen Sector outlook and iron ore price forecast It is clear that fiscal stimulus of the steel sector has succeeded. Recovery in iron ore demand, which began late 2Q09, is ongoing and should continue to support a long-term recovery in prices. · Midrex is a process by which iron ore pellets, lump iron ore or a combination of both is reduced in a vertical shaft/reduction furnace. The reduced material then flows through catalyst tubes where it is chemically converted into a gas containing hydrogen and carbon monoxide. As the iron ore moves down the furnace · Lump ore can usually fed directly into the blast furnace process, because the special processing of these ores is relatively complex and expensive, so that it is only to a certain extent economically worthwhile to process this ore. Fine ore and ore powder, on the other hand, are specially processed for the blast furnace process.

Impact of quality of iron ore lumps on sustainability of

Iron ore lumps are roughly in the size range of 6 to 30 mm and can be charged directly to the BF IRON ORE LUMPS AND FINES IN INDIA Some data of Production, Consumption, Export and Surplus availability of Iron Ore in India, in the year -04, -05,-06 are given in the Table-2.The sintering of fine ores can also be a polluting process, and mills under environmental constraints may favor direct-charge ore such as lumps or pellets. China's update to its Environmental Protection Law enforces stricter caps on industrial pollution, and has increased the appetite for higher purity ores. · The quality of lumps may have a significant impact in iron ore mining systems with implications for mineral reserve recovery rates. Improving the quality of lump ore, through a simple yet innovative mineral processing, can maximize recovery of reserves, decrease waste generation, and increase the productivity and sustainability of mines by allowing transition to lower quality iron ores.
