The role that volcanoes have in creating land is obvious to anyone who has seen the spectacular eruptions in Iceland or Hawaii. In 1943, Paricutin was a patch of barren soil in a Mexican farmer's field, now it's over 2800m high. Over time, volcanoes erode down to plains, exposing the riches that ...
Jul 06, 2016· Smelting ores and metal requires lots of energy. Air: Mining has a great effect on the quality of the air. Since mines need to blast through rock to get to an ore, dust may be produced in the process. Coal mines release methane, which contributes to environmental issues because it is a greenhouse gas.
these metal ores are the subject of this Guidebook. The Guidebook does not discuss the mining of ores that are extracted using strip mining methods, including aluminum (bauxite), phosphate, and uranium. The Guidebook also does not discuss mining involving extraction of coal or aggregates, such as sand, gravel, and limestone.
