What does mining waste consist of?
(d) Mine-dust, rock trailing
The question was posed to me by my college professor while I was bunking the class.
The doubt is from Environmental Issues topic in section Environmental Issues of Biology – Class 12
Right answer is (d) Mine-dust, rock trailing
To explain I would say: The high-volume material generated during processes of extraction, beneficiation, and further physical and chemical processing of metals and non-metals is known as mining waste. Mine-dust, rock trailing, toxic metals, etc. are included in mine waste.
