Geology, Prospecting and Exploration for Iron Ore Deposits

Apr 09, 2015· 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 buried deposits of volcanic glass or low grade iron bearing intrusives and deposits with high remanent magnetization that represent potential ore bodies.

Mining of Iron Ores IspatGuru

The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.

Mining Prospecting and exploration Britannica

Mining Mining Prospecting and exploration: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, orientation in space, and location with respect

Various sorting systems are used in other industries to separate materials, but few mining companies use them. Ore sorting in mining is usually considered a preconcentration method of upgrading run-of-mine ore before another beneficiation process. Ore sorting is a

Prospecting Wikipedia

Prospecting is the first stage of the geological analysis (followed by exploration) of a territory.It is the search for minerals, fossils, precious metals, or mineral specimens.It is also known as fossicking.. Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments.
