processing of low grade iron ore

Wikipedia · Text under CC-BY-SA licenseIron Ore Recovery from Low Grade by using Advance Methods Jan 01, 2015· The main difficulty in processing and utilization of low-grade iron ores primarily stems from their mineralogical characteristics as well as the soft nature of some ores and their high silica content. Thus, beneficiating the low-grade iron ores to remove the gangue minerals and enhancing their grade is an attractive proposition today. EFFECTIVE PROCESSING OF LOW-GRADE IRON ORE Effective processing of low-grade iron ore through separation techniques 569 found that high intensity magnetic separator tests were limited to very close range of sizes between 2 and 0.125 mm. The final magnetic product assayed 61% Fe at an iron recovery of 90.3%. However, 5% by weight was obtained as middling assaying Vale to build New Steel plant and boost dry iron ore In Carajás, as the iron content is already high (above 65% Fe), the material is only crushed and screened to be classified by size (granulometry). In some mines of Minas Gerais, the average content is 40% Fe in itabirite. To increase its grade, the ore is concentrated through processing with water and the tailings are disposed of in dams. processing equipment processing of low grade iron uganda molybdenum ore processing equipment.
