    Flotation of iron ore The main objective of iron ore flotation is to upgrade the concentrate by removing silicates and/or phosphorus-containing minerals. The use of silica flotation has increased in recent decades. The trend will continue as more complex ores have to be mined and higher-grade iron ore concentrates with fewer

    the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route

    An iron oxide ore sample was collected and sampled from an iron mine in Yunnan, China. It was at a size range of about 87.6% passing 74 microns. The ore contains 55.6% Fe, 10.5% SiO2, 1.89% CaO, 3.28% MgO, 1.36% Al2O3. The main iron oxides are magnetite, accounting for 67%. And part of them is associated with the silica gangues

    May 01, 2014 The Sydvaranger magnetite mine closed in 1996 due to low iron ore prices and was reopened in 2009. The flowsheet has remained more or less as in the old plant, based upon two grinding steps followed by magnetic separation. The magnetite is free of harmful elements and should be attractive on the high quality market. This requires a concentrate containing less than 2% SiO2
