Flocculation At Iron Ore Plant

Improving flocculation and dewatering performance of iron ...

This necessitates optimization of dewatering systems particularly in arid and semi-arid mining regions. In this paper the bench and full-scale flocculation behavior of iron ore tailings is investigated in order to improve the dewatering performance of tailings thickeners of an iron beneficiation plant.

FLOCCULATION OF IRON ORE FINES USING

calcium chloride required to achieve flocculation at pH 11.00 was 1.8 kg/t of Iron Ore fines and best flocculation was noticed only at 5 kg/t. The addition of calcium chloride not only imp~oved the settling in the alkaline range but also decreased the turbidity of the supernatant solution.

01/11/2015  This paper details a method for determining the isoelectric point of an iron oxide mineral in a siliceous iron ore. The method uses a laser scattering particle size analyzer and a pH electrode to determine the pH at which the liberated mineral particles begin to flocculate as pH is decreased. The pH at which the average particle size rises dramatically is the isoelectric point of the mineral ...

Maximizing the recovery of fine iron ore

and considerations around plant capacity and final concentrate quality. The main economic iron minerals are magnetic, haematite being paramagnetic and magnetite being ferromagnetic. This, therefore, means that magnetic separation can be applied, in principle, to all fine iron-ore beneficiation plants. While flotation has a considerable capacity advantage over magnetic separation, the real ...
