Mining could be open-pit when the mineral deposit occurs at shallow depths e.g. coal and tin and underground mining coal . All the stages of mining result in different environmental damages Newman et al. 2010 ; Al-Usmani 2011 which were highlighted in a flow chart by Ashton Love Mahachi and Dirks 2001 ; Pring Otto and Naito ...
FNX Mining Company Inc. is proposing the construction operation decommissioning and abandonment of an underground copper-nickel mine lo ed 35 kilometres southwest of Sudbury Ontario. Mining would occur for 11 years with an ore production capacity of 3500 tonnes per day.
The mining process is used to separate rock or ore from surrounding rock. There are four main mining methods: underground open surface pit placer and in-situ mining. The method used depends on the type of mineral resource that is mined its lo ion beneath the surface and whether the resource is worth enough money to justify extracting it.
2. - Assessment of risks linked to mining waste. The notion of environmental impact of mining activities is only fully meaningful if it includes a change in the initial environmental parameters due to such activities. These parameters which govern the "quality of the environment" may have several
Tailings are a type of rock waste from the mining industry. When a mineral product is mined the valuable portion is usually embedded in a rock matrix called ore.
