Environmental Impact Economics Metal Extraction mining

Metal ores are obtained by mining/quarrying and that this involved digging up and processing large amounts of rock Most ores are mined have to be concentrated before the metal is extracted and purified This often results in lots of waste material that must be dealt with from an environment of view Get price

Unit 3 Reading Mining and Mining Impacts

During the exploration process a mining company seeks an area where the desired mineral resource is concentrated and attempts to determine the size of the ore body and the mineral resource's ore grade Higher ore grades (higher concentrations) make the mining project more viable (see Table 1) Get price

Mining and Refining

Unlike the base metal ores bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade Ore quality can be improved by relatively simple and inexpensive processes for removing clay known as "beneficiation" which include washing wet screening and mechanical or manual sorting Get price

Mines and environmental impact

It is primarily from waste in the mining of sulphide ores that serious environmental problems can arise due to their content of iron sulphides such as pyrite and pyrrhotite When mining waste containing iron sulphides is allowed to lie unsheltered and comes under the effects of weather and wind it will crumble through an oxidation process Get price
