Beneficiation Strategies for Removal of Silica and Alumina
The processes selected to reduce impurity levels of these lowergrade iron ores will depend on the ore mineralogy and a thorough understanding of the separation process dynamics. The major concentration methods that may be applied to upgrade lowergrade lump iron ores include magnetic separation, wet and dry heavy media separation,
Investigation of the reverse flotation of iron ore in three
The trends and efficacy of ultrasonic pretreatment before desliming high phosphorus Australian iron ore fines was investigated in the presented fundamental study. The −1 mm iron ore fines (57.5 wt% Fe, 2.47 wt% Si, 2.15 wt% Al, 0.132 wt% P) were subjected to sonication while the ultrasonic power, duration and pumping direction were
Twostep flotation recovery of iron concentrate from
The flotation of pure and natural carbonaceous iron ore samples in the oleate flotation system was investigated. Starch can depress hematite effectively in a wide pH range, but cannot depress siderite efficiently in neutral conditions. The flotation recovery of pure hematite, siderite, and quartz in the oleatestarchCaCl2 system is significantly
Upgradation of Iron Ore Fines and Slime by Selective
Washing of iron ore fines and slime (10% and 25% w/v, slurry concentrations) with two types of surfaceactive agents (sodium humate (synthesized) and AD 200 (commercial)) at varying concentrations at pH 8 was conducted for ascertaining the efficacy of dispersants in beneficiating the lowgrade iron ores. The beneficiation process
Treatment and Recycling of the Process Water in Iron Ore
In order to ensure iron concentrate grade and iron recovery, a large number of processing reagents are selected and applied in the iron ore beneficiation. The process water carried plenty of residual processing reagents, and such wastewater with color depth and strong smell could seriously affect the environment and the local people.
Hematite Processing by Flotation Mineral
Deposits of comparatively lower grade iron ore that remain relatively untouched or bypassed, are now most important because of increase in consumer demands. Deposits of comparatively low grade
