The iron ore tailings were dried at room temperature 30±2 o C and 50 ± 5% relative humidity for a minimum of 40 hours (ASTM D 618; ASTM E 171; ASTM E 41).
A gravity concentrator namely "vibrating table" has been developed with the objective of increasing the product quality of density based physical separation processes. The …
The specific gravity of iron ore is higher than its gangue. The specific gravity of common iron ores are given with iron percentage in it. (Table 2). The common earthy impurities or gangue attached with iron ores have lower specific gravity like, C alcite/ Limestone (2.70 -2.75), Gibbsite (2.67), C lay/Shale (2.65), Quartz & Calcite (2.35).

Abstract. This study investigates the effectiveness of gravity and magnetic concentration techniques for the beneficiation of a Sudanese iron ore, the newly discovered Wadi Halfa iron ore deposit. It is a low-grade type of ore with high silica content, more than 45% SiO 2, and an average iron content of about 35% Fe.
Gravity concentration has been adopted over the years, as a pre-concentration or primary concentration process of HMs with the use of a viscous medium, which is mostly water. ... compared the efficacy of a Kip Kelly dry-air tabling process and a Wifley wet tabling process on an iron (Fe) mineral ore with liberation particle size of −500 + 355 ...
Gravity concentration spirals are optional in gold processing, used for carbon degritting. Iron ore Gravity concentration is used in iron ore processing. Following a range of screening processes, large assemblies of spiral concentrators are located downstream of a cyclone cluster and are used in classifying iron ore fines from waste.
