abandoned mines. Historical mining practices, ore processing techniques, disposal practices, closure procedures, and/or surface exposure of ore deposits at AML sites have resulted in the generation and disposition of large quantities of mine wastes, including waste rock, mine tailings, mine drainage water, processing chemicals, and other wastes to
Mar 26, 2021· The cement and mining industry are also presented, as positive and negative cases, respectively, of circular economy in solid waste management. The mining industry is under pressure to minimise the risks related to its waste, which caused severe accidents in the last years. Materials recycling in Brazil (mainly plastics) is also presented.
Iron mining operations began on the Mesabi Range in 1884 where strip mining was the most common method used to gain access to the ore. The open pits mines and spoils banks formed from the removal of overburden to gain access to the ore are still present today. As the rich ore was depleted taconite mining operations began.
