of iron ores by gravity separation method is studied The ore samples are beneficiated with a view to produce sinter quality concentrate The soft laminated ore contained 6129% total iron, 504% silica and 429% alumina while the Goethiticlateritic ore contained 5334% total iron, 74% silica and 549% alumina Liberation analysis of different size fraction suggested that grain size

Effective processing of lowgrade iron ore through separation techniques 569 found that high intensity magnetic separator tests were limited to very close range of sizes between 2 and 0125 mm The final magnetic product assayed 61% Fe at an iron recovery of 903% However, 5% by weight was obtained as middling assaying 314% Fe These middling products, together with

find that inspite of the complex mineralogy of iron ore, beneficiation results using gravity separation like multi gravity separator (MGS), particularly in finer size ranges was encouraging The result of oregangue mineralogical studies were found quite useful in evaluating the separation efficacy of gravity separation process The process mineralogical data

The true specific gravity of iron ore is approximately 5t/m3 and is quite different from the specific gravities of major impurities such as silica and alumina (approximately 27t/m3) Gravity separation is a method of separating iron ore from impurities on the basis of the difference in their specific gravities Gravity separators include jig separators, which utilize the difference in

medium separation (HMS), is a form of gravity concentration technology involving floatsink separation that historically has been used predominantly in the coal and diamond processing industries Many other industries have used DMS, which include iron ore, complex sulphides, base metal oxides, precious metals, and various industrial mineral industries such as

Dense Media Separation on Iron Ore Feed Floats sieve bend Overflow Sinks Dense Media Separation on Iron Ore DMS Drum Sinks DMS Drum Floats • DMS Drum –Up to 46m diameter –Process 600t/h lumpy iron ore • DMS Cyclone –Only 6mm material for iron ore –360mm diameter cyclone –Process 40t/h per cyclone • Larcodems –90+6mm stones –12m diameter

minerals to separation by gravity technique, can be expressed as presented in Equation 1 ( Rath and Singh, 2007) CC = (dh−df) (dl−df) (1) where: d h is the specific gravity of the heavy mineral; d l is the specific gravity of the lighter mineral; d f is the specific gravity of the fluid In general terms, when the quotient is greater than 25, whether positive or negative, then gravity
