lithosphere 3
lithosphere 4 (2)
-iron displacement:
-
-therefore the iron will dissolve into solution and the copper ions will be deposited as solid copper metal that can be collected
-mechansation:
-
-
-larger machinery especially important in open cast mining as it allows quick extraction of overburden and minerals to be extracted quickly and cost effectively
-
-eg, Bingham coal mine - since 1906, pit 970m deep, 4km wide

lithosphere 5
-surface mining:
-
-
-more waste removed ,eg from overburden
-
-
-quarrying:
-mostly used for aggregates eg. sand, or building materials such as slate
-eg, Dry rigs quarry in Yorkshire Dales for gritstone
-
-
-
-long wall mining:
-
-
-
-
-
-eg, Kellingley colliery, north Yorkshire England
-
-deep cave mining:
-
-
-
-eg, Sygun copper mine, Wales - Snowdonia national park

-
-smelting process:
-roasting of ore minerals eg, iron ore with other substances such as carbon that chemically reduce them to contained metals
-
-oxides are more suitable for smelting so sulphides are usually converted to oxides by roasting in air
-
-a flux is added during smelting to combine with impurities and gangue minerals to form a silicate metal called slag
