30 06 2021 This is how the ore is further pulverised until it s a fine powder and from here it s put through the secondary magnetic separators and de sliming elutriation columns The in pit crushers We have four in pit crushers each standing seven stories high and able to crush more than 4 000 tonnes of ore an hour these are the largest in pit crushers in Australia
Finex is an innovative ironmaking process based on the direct use of fine ore and non coking coal In the Finex process fine iron ore is directly charged at the top of a cascade of fluidized bed reactors where it is heated and reduced to direct reduced iron DRI by means of a reduction gas derived from the gasification of the coal in the melter gasifier
Sulphide ores can be easily wetted by the oils which will float on water These minerals are first converted into a fine powder and then mixed with water After that pine oil is poured into this slurry Then Air bubbles are created by injecting high pressure air Thus the sulphide ore comes on
