Surface Mining Surface mining methods are used when ore deposits are located close to Earth’s surface. Open-pit mining is a method that is often used when large quantities of near-surface ore are mined. Coal and metals such as gold and copper are mined using the open- pit method. In an open-pit mine, the ore is mined downward, layer by layer. First, explosives are used, if needed, to break up the ore. Then, the ore …

Lecture 2: An introduction to mining - SGU

This lecture covers mining and introduces how mining generally is done, what machinery and methods are used and how ore and waste rock travel within the mine complex. Mining is done to liberate minerals from the crust of the earth. This is done in several steps.

Lecture 1: An introduction to minerals, ore and exploration

Metals are extracted from minerals. Minerals are naturally occurring, inorganic, solid chemical compounds, which often forms crystals. A rock is composed of one or several minerals. While all rocks contain metals, not all rocks are considered valuable enough to mine. It is possible for rocks to contain so called mineralizations, which is a deposition of valuable minerals in a large quantity. These …

Mining Impacts . Underground mining usually only disturbs a relatively small area. Abandoned mines may collapse causing subsidence problems if near the surface. This type of mining can be very expensive and less is being done. Surface mining usually done as an open pit (quarry) or by strip mining. Open pits often leave a very large hole in the ground. May be used as a lake. Strip mining …

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. Besides, metal ores can be magnetic as well as electrically ...
