It has been Vol.7, No.1 Effective Beneficiation of Low Grade Iron Ore 33 observed that separation efficiency is better at higher amplitude. It has been also inferred that higher amplitude is needed to lift the coarse particles.
techniques adopted for the beneficiation of iron ores and utilization of natural fines by flotation column arediscussed. IndIan Iron ore resources: Indianironores generallycontain hematite,magnetite,limonite and siderite minerals. In the total iron ore reserves of about· 17.712 billion tonnes, hematite is about 12.3 billion tonnes
The beneficiation of low grade iron ores has received many attentions in the recent years due to the depletion of high grade iron ore reserves and the raising demand around the world for steel making. The smelting of low grade iron ores through the blast furnace or direct reduction method results in some problems such as
Barsua iron ore mine in India has adopted Remco Jigs for beneficiation of low grade iron ore fines. Batemans Apic jig is being used in iron ore mines of South Africa and has demonstrated how the technology is suitable for the separation of fine ferrous ores. A Batac jig is installed to reduce alumina content of iron ore fines from Noamundi
Low grade Iron Ore Beneficiation and the Process of Jigging Iron ore resources are getting consumed at an accelerated rate because of the growth in the production of iron and steel. Due to this reason the availability of high grade iron ore is reducing and the supply of high grade iron ore to iron and steel plants is declining sharply.
