GEOPHYSICAL TECHNIQUES AND THEIR APPLICATIONS IN MINING

Historically, geophysical technique (magnetic) was first used in Sweden in the 17th century for prospecting iron ore (Reedman, 1979). Geophysical techniques gained more acceptability in the early 1923 (Gupter, 1986) because of exploration for crude oil. Relevance of Geophysics across the world is as a result of oil and solid mineral exploration.

Iron Ore

From 1915 to 1965 the Iron Monarch and Iron Baron-Iron Prince mines were the main supply of ore for Australia''s iron and steel industry. The favourable logistics of low cost of ore extraction and the nearby portsite at Whyalla, led BHP to establish an integrated steelworks at Whyalla in 1964.

Iron Ore Mining | Techniques | Metal Extraction

MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.
