Economic Impacts Of Open Pit Mining Sep

Open-pit mining often involves the removal of natively vegetated areas and is therefore among the most environmentally destructive types of mining especially within tropical forests. Overburden also called waste or spoi l is the material that lies above an area with economic or scientific interest.
