CHAPTER 1 ENGINEERING OF MINERAL EXTRACTION
Surface Mining. Surface mining is the removal of material from the earth in excavations that are open to the surface. In some cases, material is removed directly from the earth's surface; for example, sand and gravel may be removed directly from deposits of those materials put in place by ancient lakes or rivers.

Geology, Prospecting and Exploration for Iron Ore Deposits
Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earth's crust.

Iron ore beneficiation: an overview
Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has …
