Recovery of Iron Values from Iron Ore Slimes using ...
Mining wastes include waste generated during the extraction, beneficiation or processing of minerals like iron ore fines, slimes and tailings. Approximately 10–20% of the raw material is discarded as slimes in to slime ponds/tailing dams. Recovery of iron values from slimes result in economic benefit by utilization of waste as a resource and minimizes the threat to the environment.
Characterization and processing of iron ore fines …
The beneficiation potential of the iron ore slimes produced from the washing plants and tailing ponds of Kiriburu mines assaying up to 60% Fe, 3.34% SiO 2, and 2.93% Al 2 O 3 is analyzed. To start with, the ore slime was characterized in sufficient detail to reveal that it is extremely fine — 80% below 110 μm and contains substantial amount of goethite (Fe 2 O 3 ·H 2 O).
Effectiveness of sodium silicate as gangue …
4-10-2011 · Abstract. The recovery of iron from the screw classifier overflow slimes by direct flotation was studied. The relative effectiveness of sodium silicates with different silica-to-soda mole ratios as depressants for silica and silicate bearing minerals was investigated.
Recovery of Iron Values from Slimes and …
During crushing and wet processing of iron ore on an average 15- 18% slimes (-100 mesh) are produced in the iron ore mines of Nationa Mineral Development Corporation (NMDC). About 50 to 65% by weight of slimes can be rec- overed and upgraded to +64% Fe by process of hydrocycloning. By the process of wet high intensity magnetic separation, the magnetic concentrate assaying +65% Fe with …
Gold extraction - Wikipedia
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...

Treatment of iron ore slime for value addition - …
Research Highlights Iron ore slime which is a waste material contains 56% of iron. Two different stone treatment methods and electrowinning method were separately studied to upgrade iron content up to 60% or above. Acid extraction and alkali extraction can upgrade iron content maximum 63% (w/w) and 65 % (w/w) respectively. Electrowinning directly produces high purity iron without ...
