Dec 17, 2016 One of the problems is that mining has become more mechanized and therefore able to handle more rock and ore material than ever before. Therefore, mine waste has multiplied enormously. As mine technologies are developed to make it more profitable to mine low grade ore, even more waste will be generated in the future. Waste from the Mining Process
The presence of metal sulfide minerals in portions of the waste rock is a cause of particular concern because of the possibility of AMD, and so proper characterization of the chemical properties of waste rock throughout the mining process is an important first step in addressing this potential hazard
Environmental impacts due to mining manifest as water pollution, land degradation, loss of biodiversity, air pollution, increase in health related problems, occupational noise pollution, vibrations, land subsidences and landslides. Karnataka being one of the mineral rich states of the country, mining provides substantial non-tax revenue
