Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process. Aiming towards the good quality (>60% Fe) ore and its nonrenewable nature, the mineral rich ore is depleting, and the slimes are increasing at a rate of ∼11–13% for the hematite reserves in India, as reported by theIron Ore 2nd Edition Elsevier,Description. Iron Ore: Mineralogy, Processing and Environmental Sustainability, Second Edition covers all aspects surrounding the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trilliondollarayear metal market and is the backbone of the globalMINERAL PROCESSING OF NONFERROUS METALS A ,Feasibility of Producing Pellet Grade Concentrate by Beneficiation of Iron Ore Slime in India. Subrata Roy, A. Das, M. Mohanty; Materials Science. 2007; 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,
Physical processing of lowgrade (28% Fe) iron ore slime from Krivoy Rog province of the Ukraine is investigated. The slime is shown to have drastically different characteristics from those of Indian iron ore slimes. Effective recovery of iron values through physical beneficiation of the Ukraine slime is achieved. It is observed that a concentrate Dry beneficiation of iron ore Mineral Processing,The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used.

Basically it separates Fe2O3 or Fe3O4 from other impurities in the iron ore. In this process the Fe content is improved to maximum possible extent.Beneficiation of Iron Ore Mineral Processing,Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the nonmagnetic type which Beneficiation Strategies for Removal of Silica and Alumina ,The processes selected to reduce impurity levels of these lowergrade iron ores will depend on the ore mineralogy and a thorough understanding of the separation process dynamics.

Washing of iron ore fines and slime (10% and 25% w/v, slurry concentrations) with two types of surfaceactive agents (sodium humate (synthesized) and AD 200 (commercial)) at varying concentrations at pH 8 was conducted for ascertaining the efficacy of dispersants in beneficiating the lowgrade iron ores. The beneficiation process Mineralogical and Chemical Characterization of Low Grade ,The consumption of iron ore has increased rapidly over the past decade due to the tremendous growth of iron and steel industry. The depletion of high grade iron ore resources make it inevitable to utilize the existing low grade iron ores/fines/tailings with effective beneficiation to meet the present specification and demand. Enormous amounts A Beneficiation Study on a Low Grade Iron Ore by Gravity ,In this paper, a sample from Tangezagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main ironbearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others.
