Magnetite - Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...

Exploration of Porphyry Copper Deposits

Jun 22, 2015  Now all three of these geophysical methods are indirect; used to detect the alteration and not necessarily the mineralization. We still don’t know how much copper, gold or molybdenum the rocks contain and whether they have received enough upgrading from the crustal average to be economically mined. We need chemical assays to determine this.

(PDF) GEOPHYSICAL TECHNIQUES AND THEIR APPLICATIONS

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.
