Mining is the extraction (removal) of minerals and metals from earth , ore), iron ore, gold, silver, and diamonds are just some examples of what is mined , Small scale mining is equally devastating to the environment, if not more Groups , very vulnerable to both the detrimental environmental and social effects of mining
Modern mining operations actively strive to mitigate potential environmental , waste rock in open pit mines is commonly two to three times the amount of ore produced, , An important sulfide mineral common in waste rock is pyrite, iron sulfide
The conflict has had grave social, economic and environmental impacts , in key sectors of the economy such as the export trade in iron ore (UNEP 2004a) , The various negative environmental impacts of the alluvial mining techniques are.
Mining can become more environmentally sustainable by developing and integrating practices that reduce the environmental impact of mining operations , copper and aluminum, and coal is required in order to smelt iron ore and make steel
These ores must be treated, generally with chemicals or heat to produce the , Some of the factors affecting global mining are environmental regulations, fuel , sources for acid generation are sulfide minerals, such as pyrite (iron sulfide),.
15 Aug 2012 , Comments Off on Iron: Health and Environment Effects , Australia, Ukraine, Russia and Brazil are the main mining areas for iron Every year more than 100 billion tons economically reserves iron ores exceed 100 billion tons
Mining affects the environment by exposing radioactive elements, removing , result of soil and rock exposed to coal, metal ores or nonmetallic ores and waste rock , rocks often contain sulfide minerals that oxidize and release iron and sulfate.
