Why Is OpenPit Mining So Devastating to The Environment?
The Toxicity Affects the Air As per the Department of Environment list, some minerals mining causes more damage to the environment than others And one such devastating effect on the environment by open pit mining is air pollution Those minerals include coal, gold, limestone, manganese, iron ore, lead, zinc, copper, pyrite, bauxite,
Surface Mining Techniques used in the Oil Sands
Surface mining is defined as the extraction of ore from an open pit or burrow Surface mining is sometimes known as openpit, opencut or opencast mining and is only commercially viable if the deposit is located relative close to the surface Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined
