Decent Essays

ICMM (International Council on mining and metals) has conducted ten case studies of “mining countries” and with better methodology to have better understanding and assessment, they found out that mining may contribute to national economies. According to (ICMM, 2010) mining may help to reduce poverty and indirectly induce employment. From mining too, it helps to increase government revenue to help increase development of the country.
Mining project starts with mineral ore exploitation and ends with post-closure period. Generally, each phase of its activity is influenced and associated with different environmental impacts. The first phase of mining is start with exploratory phase. During this phase, surveys are made and that include …show more content…

Metallic ores contain elevated levels of metals but they generate very large quantities waste called tailings. When active mining ceases, the mining sites are closed. This is the last phase of mining activity, the post-closure period. The objective of site reclamation is that the site should be return to the pre-mining conditions. The impacts persist for decades or even centuries.
Perhaps the harmful effects of mining operations are due to mining technology and techniques, which include enormous open pits in the ground. At a very beginning of mining activities, the impacts have already started and the effects will last for decades. Trees are cut down to build road in order for the large machineries to access as shown in Appendix A. Deforestation occurs and this may lead to soil erosion.
Before environmental laws and standards were adopted, most of the mining company dumped tailings (wastes) in the nearest location. Extracting metals use high demand of water and for water disposal. It pollutes fresh water and as a result water is contaminated with harmful constituents such as mercury (Appendix B). Example of former open pit mine is Butte, Montana known as the Berkeley pit (Appendix B). It was closed in 1982 but the pit and its water present a serious environmental issue. In 1995, there was a flock of snow geese landed in the pit and a total of 342 carcasses were found and today, Berkeley pit consists with highly contaminated water as stated by (Barbey, 2009).
