Mining Operation: Types, Impacts and Remedial Measures

In order to separate and purify the metal from other impurities in the ore, smelting is done which emits enormous quantities of air pollutants. Oxides of sulphur, arsenic, cadmium and lead etc. shoot up in the atmosphere near the smelters and the public suffers from several health problems. 6. Noise Pollution:

Surface discharge of excess mine dewatering water and other waters to main waterways may contain excess quantities of arsenic, total dissolved solids, boron, copper, fluoride, and zinc. When mining operations cease, and the water pumps are dismantled, these large open pits may slowly fill with water, forming lakes.

 · As iron is also mobile in low pHenvironments, elevated iron concentrations are common in uranium mining areas. When the pH values increase over the course of the stream, ironoxides and the sorbed (semi)metals can precipitate or coprecipitate. This can cause elevated (semi)metal concentrations in the stream sediments ( Neiva et al., 2014 ).
