RECLAMATION OF KYANITE MINE TAILINGS WlTH SURFACE RECONFIGURATION

Case History of a Copper Mine Tailings Pond Reclamation in Ducktown, Tennessee

Cessation of mining operations in Ducktown, TN, left 800-900 acres of barren copper mine tailings. Revegetation activities had met with limited success. In 1998, efforts for revegetation of the tailings materials began anew. The objective of this case history is to provide insight into decision making processes which resulted in conversion of 800-900 acres of barren mine tailings into a vegetat...

Western Surface Mine Permitting and Reclamation (Part 10 of 15)

Tree-Substrate Water Relations and Root Development in Tree Plantations Used for Mine Tailings Reclamation.

Tree water uptake relies on well-developed root systems. However, mine wastes can restrict root growth, in particular metalliferous mill tailings, which consist of the finely crushed ore that remains after valuable metals are removed. Thus, water stress could limit plantation success in reclaimed mine lands. This study evaluates the effect of substrates varying in quality (topsoil, overburden, ...

Preventing acid mine drainage from mine tailings
