The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens. Very fine …

Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction.

flowsheet. Basis of design The basis of the plant design is the treatment of an oxide/secondary sulphide deposit treating a 4 per cent copper head grade and a 0.05 per cent cobalt head grade at a treatment rate of 2.5 million tons per annum. This will provide a feed tonnage of 100 000 tons and 1325 tons per annum of copper and cobalt respectively.
