· Some of the environmental damages caused by tin mining in Jos Plateau include damage of pastoral land while exploring for cassiterite, mine waste dumps and mine tailings consisting of radioactive waste. These mine ponds have led to a number of deaths. In addition, during mining of tin, radioactive minerals are liberated into the environment.
· Impacts on the environment due to the extraction of iron from haematite does not only start during the extraction of iron from the ore it starts when the raw materials are being mined and transported. The following are problems which arise from these processes: From mining and transporting of raw materials Air pollution Noise pollution
Occupational and environmental exposure to heavy metals, silica, and asbestos can occur during mining and milling operations. The smelting process (extracting the metal from the ore) is associated with the highest exposures and environmental releases. The hazards to human health caused by exposure to heavy metals – including lead, cadmium and ...
· Atmosphere: Pollutes the air with dust. This affects wildlife and creates poor air quality in the area. When coal is burned it releases many harmful chemicals into the air, such as methane (greenhouse gas) and contributes to global warming Biosphere: Destroys plant and animal habitats (kills plants, destroys resources that animals use) and causes animals to leave or die (read more about mining ...

The Gold Rush, positive for California in so many ways, had a devastating effect on the state's environment. Many of these problems were directly related to goldmining technology. The process of hydraulic mining, which became popular in the 1850s, caused irreparable environmental destruction. Two images show California's largest hydraulic mine ...
Many of these problems were directly related to goldmining technology. The process of hydraulic mining, which became popular in the 1850s, caused irreparable environmental destruction. Two images show California's largest hydraulic mine — Malakoff Diggings, in Nevada County — in action.
process of sand mining has accelerated coastal environmental degradation to an alarming rate. Biological Environment Sand mining is one of the main threats to the rich biodiversity alongside our perennial rivers and ephemeral water courses. It can destroy riverine vegetation, cause erosion, pollute water sources and
· Different types of mining have various impacts on land. For example, strip mining results in the clearing of trees, plants and topsoil [2]. One effect of this type of mining on the environment is the pervasive problem of soil erosion, which in turn leads to the pollution of waterways.. Another destructive type of mining is underground coal mining.
· Learn what mine tailings piles and tailing ponds are, ... Tailings deposited as large piles can cause a variety of environmental problems: ... or it can be a byproduct of ore processing.
Mining operations mobilize large amounts of material, and waste piles containing small size particles are easily dispersed by the wind [2]. The survey revealed 74 respondents (representing %) of the total sample population admitted that mining methods affect the environment with just 1 respondent (%) failing to acknowledge this fact.
