Resolution Copper Mining - Alternative 5: Peg Leg Water Balance - Additional BADCT Technologies to Reduce Seepage
This technical memorandum describes an evaluation of the GoldSIM model seepage results incorporating additional seepage controls and Best Available Demonstrated Control Technologies (BADCT) such as “thin lift” deposition. The additional BADCT controls include modifying the conventional thickened tailings deposition to thin lift deposition when sufficient surface area becomes available for this method of tailings deposition to function.
