The utility of magnetic separation in iron ore beneficiation has been widely reported earlier (Pradip, 1994;Jena et al., 2015;Das et al., 1991;Li et al., 2010;Song et al., 2002; Raj et al., 2007 ...
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

slimes generated during beneficiation contain an iron value of 40-55%, which are being discarded till now and is dumped in mines heads. Significant quantity of slimes, about 18 - 25 % of ROM has been generated during wet ... improved product quality has also forced iron ore producers to review process flow sheets . and evaluate alternative or ...
Falling prices for iron ore with lower quality than 60 % Fe have led increasingly to the design of iron ore beneficiation lines. General problems of water scarcity and risks with tailings dams have led to the focus shifting to dry beneficiation technologies. In the following article, current developments are examined and case studies referenced.
Two conceptual flow sheets have considered for the beneficiation of Indian high alumina iron ore fines. The first option, consisting of hindered settling classifier followed by two stage gravity concentration results in a product quality with 66.82%Fe and 2.1%Al 2 O 3 content ensuring 25.15% iron recovery. ...
This culminates into low grade, fine grain size, complex ore mineralogy, and poor liberation, thus, causing the beneficiation of lead-zinc ore a challenging task.
