Geology, Prospecting and Exploration for Iron Ore Deposits

Apr 09, 2015 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.

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

Iron Ore Mining Techniques Metal Extraction

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

Mining of Iron Ores IspatGuru

Mar 14, 2014 Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods.

Detailed mapping on 1:2,000 or 1:1,000 scale. Pitting, trenching and bed rock sampling on all out- crop sections. Drilling on systematic pattern upto 60 to 120m depth and at 100m strike interval for gold, 200m for base-metals and 400m 500m for limestone.

A modern and important variant of this method is known as vertical crater retreat (VCR) mining. A few examples of commodities mined by this method include iron and palladium. Open stoping. This type of mining is used to recover steeply dipping orebodies in competent rock. The ore is removed from the stope as soon as it is mined.

Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their

Iron ore Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO

Magnetic and Gravity Methods in Mineral Exploration: the

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.

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.

Mining Underground mining Britannica

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the
