·In pyrometallurgical process Al and Si bearing minerals in iron and aluminum ores are easily transformed into sodium aluminosilicates in the presence of Na2O constituents which alters the leaching behaviors of Al2O3 and SiO2 It was confirmed that sodium aluminosilicates with different phase compositions synthesized at various roasting conditions
·The market requirements for higher grade concentrates of iron to improve the productivity of the iron and steel industry has increased the importance of the flotation process with respect to the conventional preconcentration of ore by gravity or magnetic separation
·In general the industrial flowsheets for the beneficiation of itabirite iron ores from the Quadrilátero Ferrífero Minas Gerais state in Brazil involves grinding desliming magnetic separation and cationic reverse flotation using both mechanical and columns flotation cells At Brazilian plants it is estimated that Fe losses generated at the slimes stage range
·Work done in dry beneficiation iron ore is limited to magnetic separation and dense media fluidization Pre concentration of lean hematite and limonite ores using a dry high intensity magnetic separator was reported by Zhang [] Chen [] reported iron impurities dry separation performance using a novel dry vibrating high gradient magnetic separation method
·With gradually diminishing Fe grade in tandem with the ever increasing demand for high grade iron ores iron ore industries are now focusing on the beneficiation of low grade iron ore fines
·ABSTRACT There is an urgent need for development of environmental friendly processes through which iron ore fines can be beneficiated and utilized effectively For processing of low grade iron ores ground to finer size necessitates the use of centrifugal force This is because the settling rate of the particles in centrifugal force is 500 600 times more than that
