Underground mining has the potential for tunnel collapses and land subsidence (Betournay 2011) It involves large-scale movements of waste rock and vegetation similar to open pit mining Additionally like most traditional forms of mining underground mining can release toxic compounds into the air and water

Uranium resources can be extracted from the ground in three ways: open pit underground and in-situ leach (ISL) Open pit mining also known as strip mining is the removal of surficial soils and uneconomic rock to get at the ore below Ore grades are normally less than 0 5% This is type of mining is only possible if the uranium ore is


Mining Two different mining methods are used for copper ore: Traditional mining – Ore is mined from the ground in an open pit (90% is mined this way) or undergrounds mines Leaching – ore is treated with diluted sulphuric acid that trickles through the ore This then dissolves the copper to form copper sulphate

They provide for less waste rock removal and they offer less environmental impact than open-pit mining because these deposits typically have much higher ore grades In-Situ Leach (ISL) Mining: Some ore bodies due to ore concentration or the surrounding material can only be accessed by dissolving the ore body using water soluble acids or

To satisfy this demand heavy investment has been seen in mining assets in Canada South America Australia Asia and Central Europe amongst others In addition some mining companies are looking at ways to get to quality reserves in non-traditional locations including Mongolia the Democratic Republic of the Congo Afghanistan and Mauritania

In each of these mining methods various earth-moving equipment including shovels dozers hauling trucks and loaders are used to remove and transport the ore However the first step is to loosen the rock in the ore body so that it can be moved and processed Blasting and grinding equipment are used to accomplish this task
