Mining - Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Ghana - Mining Industry Equipment

Aug 31, 2020· The mining sector plays a vital role in the Ghanaian economy, as it attracts more than half of all foreign direct investment (FDI) and generates more than one-third of all export revenues.

5. The technology of mining and metallurgy

Yet progress in ore-upgrading technology has been more important for iron ore. Increasing the size of blast furnaces and the application of stricter operational standards resulted in the development of techniques for preparing and upgrading the ores before they can be used to produce pig iron and steel.

How do we extract minerals? - USGS.gov

The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
