  • Grinding Iron Ore in a Wet Autogenous Mill

    The Cretaceous plant at the Hill Annex mine of the Jones & Laughlin Steel Corp. was designed with a wet autogenous mill for grinding low grade iron ore so that it could be concentrated by spirals and flotation cells. The plant, on the west end of the Minnesota’s Mesabi Range, went into operation in June 1961, and preliminary operating and metallurgical information describing the performance

    The largest reduction in throughput in AG milling (45%) was observed for the softest ore (GAL-IF) operating in closed circuit, which could be explained by the inability of the ore to perform as autogenous grinding media, given its fineness and low competence . This was also the ore associated with the largest increase in SSE.

  • autogeneous grinding of iron ore

    autogeneous grinding of iron ore. This invention relates to the roasting of iron ore particularly the thermal conversion of iron ore to gamma hematite by an autogenous roasting process BACKGROUND TO THE INVENTION When iron ores are roasted at temperatures above about 1500° F the magnetite mineral contained in the ore oxidizes rapidly enough to act as a significant source

    Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines’ autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.
