The beneficiation of low grade iron ores to meet the growing demand for iron and steel is an important research topic However certain ores do not qualify to be treated in physical separation processes and hence alternative strategies are being looked into for upgrading their iron content


The management of tailings from iron ore mines is an important issue not only from the point of view of pollution control but also of the conservation of resources As per the guidelines of IBM the iron content in the tailing should be below 45% In view of the above CSIR NML had undertaken study on characterization and beneficiation study of iron ore slime from eastern part of India and

Iron ore Confounding the expectations of experts Edison

 · The crushed ore must then be purified/concentrated to increase the proportion of iron in a process of beneficiation Various methods are used in beneficiation most notably gravity separation and flotation for haematite see below and magnetic separation for magnetite A number of beneficiation techniques fall under the banner of gravity separation ranging from shaking surfaces


Beneficiation is the process where ore is reduced in size and gange separated from the ore Since all iron ore deposits have unique mineralogy the beneficiation process is specific to each deposit Separation of certain minerals can be efficiently achieved by taking advantage of the physical electrical and magnetic properties SGS provides a comprehensive range of test work services for the


techniques for the beneficiation of a Sudanese iron ore the newly discovered Wadi Halfa iron ore deposit It is a low grade type of ore with high silica content more than 45% SiO 2 and an average iron content of about 35% Fe Based on the fact that there are appreciable differences in specific gravity and magnetic susceptibility between the desired iron minerals and the gangue minerals it
