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 surface-active 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 low-grade iron ores. The beneficiation process Slime sample. Iron ore slime sample from the Barsua iron ore mines, which supply iron ore to Rourkela steel plant was taken for the detailed studies. 500 kg of the representative sample was collected from the existing slime pond and brought to the laboratory for detailed coating and magnetic separation studies.

Iron ore slimes beneficiation using optimised ScienceDirect
The iron (Fe) content of such ores ranges from 72% to 35%. The highly friable and fully liberated constituents in ore, such as alumina and silica, generate a large quantity of fines during mechanized mining and crushing. Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process.Section snippets Slime sample.

Process to Recover Iron Values from High-Alumina Indian Iron Ore Slime
In India, approximately 15–20% of Run of Mine (ROM) from any iron ore deposit is reported to slime dam as a byproduct of the iron ore beneficiation process. The proportion of iron ore slime to ROM will increase in the future, with a higher proportion of lean-grade ores in ROM. Furthermore, tonnages of iron ore slime will increase with Iron ore slimes of India contain high alumina and silica that reduce the grade and pose difficulty in processing. This investigation addresses the interactive effect of process parameters on the processing of Indian iron ore slimes by using column flotation.The iron ore slime containing 58.7% Fe, 5.2% SiO 2 and 4.9% Al 2 O 3 was Response of process parameters for processing of iron ore slime
