Iron ore is the basic raw material for iron and steel making. India is among the leading producers of iron ore in the world and produces about 150 million tons per annum (U. S. []).The total reserves of iron ore in India is around billion tons, of this hematite ore is considered to be the most important iron ore because of its high grade quality and lumpy nature.

WhatsApp: +86 188380728291. Introduction. The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and recleaner spirals (Bazin et al., 2014).The development of spiral circuit flow sheets and the tuning of ...
WhatsApp: +86 18838072829Results show that knowing the mineral size distributions in the spiral feed is necessary to forecast spiral performance. Further, in the case of iron ore processing, the separation process is practically complete after four turns, with wash water affecting the process rate of recovery.

WhatsApp: +86 18838072829Beneficiation 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.
