Magnetic exploration may directly detect some iron ore deposits (magnetite or banded iron formation), and magnetic methods often are an useful for deducing subsurface lithology and structure that may indirectly aid identification of mineralized rock, patterns of effluent flow, and extent of permissive terranes and (or) favorable tracts for deposits beneath surficial cover.

09.04.2015· In case of iron ores, the detailed magnetic study of anomalous areas may involve using a magnetometer in a helicopter, or ground surveys employing hand-held or other portable magnetometers. A new electromagnetic prospecting technique known as AFMAG (audio frequency magnetics) has been used in areas where magnetic anomalies have been detected to attempt to differentiate between

uses raw materials including iron ore, coal, limestone and recycled steel. On average, this route uses 1,370 kg of iron ore, 780 kg of metallurgical coal, 270 kg of limestone, and 125 kg of recycled steel to produce 1,000 kg of crude steel.2 • Route 2: The electric arc furnace (EAF) route uses primarily recycled steels and direct reduced iron (DRI) or hot metal, and electricity.

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron

BENEFICIATION OF IRON ORES A. Das and S. Roy INTRODUCTION Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non-magnetic fraction, e.g., separation of magnetite
