Challenges and potential approaches for soil recovery in iron open pit mines and waste piles

The revegetation of areas impacted by iron mining may be hampered a series chemical and physical impediments exhibited those areas. Physical problems, such as penetration resistance steep slopes, outweigh the that both should considered for soil recovery. This study aimed to evaluate main attributes are directly related plant growth on affected activities discussing possible solutions. For this purpose, including open pit mines, waste piles native forest in Carajás Mineral Province were analysed. results show pits had low medium levels P organic matter micronutrients B, Zn Cu. In piles, parameters less hindering than pits. Soil was higher forest; however, there reduction up 69% rainy season. principal problems observed mine can easily corrected, although inclination slopes combination with elevated density increase risks losses fertilizers seeds runoff. Penetration is most serious problem development plants pits, use irrigation water help maintain tolerable proper root species.
