That answer, unfortunately, isn't straightforward. Odell explains that making an apples-to-apples comparison is challenging, because methods for extracting and processing oil and coal are different than those for metal mining. Even mining two different metals—or two different deposits of the same metal—can call for different techniques.

The elemental riches of the earth – from gold to uranium to coal – come at a cost. Mining generates millions of gallons of wastewater and, along with industrial wastewater and sewage, is one of the main sources of water pollution [1]. Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and ...

Air pollution In Zambia, the mining industry (mostly the copper smelters) contributes to over 98% of the country's SO 2 emissions. In the early 2000s, the total SO 2 emission was 346 700 ton/year (En - vironmental Council of Zambia 2008). Recent investments in mining activities are expected to yield increased SO 2
