gravity separation as well as high and low intensity magnetic separation for wet and dry applications for fine iron ore. Our laboratory has the capability to create multi‑stage pilot scale circuits to treat bulk samples (80‑100 tonnes) for process testing and circuit optimisation. We deliver metallurgical testwork for iron ore

Though wet beneficiation technologies for iron ore are well established, owing to issue like disposal of reject as slurry, the development of dry beneficiation technology is being felt by the concerned Industries. A bench-scale dry gravity separator is fabricated, and detailed experimental studies were carried out to evaluate its performance.

Abstract Beneficiation of low grade iron ore slime from Chitradurga, India was studied with a view to produce pellet grade fines. The slime sample had a feed grade of 49.86% total Fe, 7.93% Al2O3, and 10.19% SiO2. Kaolinite and quartz was found to be the main gangue minerals and they formed porous and friable oxide and hydroxide of iron. …

In India, magnetic concentration is very effective method for the beneficiation of iron ore, nearly 90% of ores are concentrated by this method (Ryan 1991) (Table 1). Approximately 20 -35% of all the unit of iron lost their value by magnetic separation, because hematite ore of iron is weakly magnetic response. The Magnetic separation can be

In the present investigation an attempt has been made to beneficiate goethitic iron ore containing 59.02 % Iron, 6.51 % Alumina, 4.79 % Silica, 0.089 % Phosphorus with 7.11 % loss on ignition. For this purpose, different beneficiation techniques such as gravity and magnetic separation processes have been employed. During the process two …
