As part of the Pennsylvania Department of Environmental Protection (DEP) Abandoned Mine Reclamation Grant Program to the Southern Alleghenies Conservancy (SAC) a program (Resource Recovery Phase 3) was executed to promote the recovery of mineral resources from abandoned mine drainage treatment. The Grant was being used to fund various projects, of which Concurrent Technologies Corporation (CTC) was tasked to conduct a metallurgical evaluation of selected acid mine drainage (AMD) treatment residuals. The SAC worked with CTC to identify eight different AMD treatment residuals to evaluate for the potential use in self-lubricating bearing materials. CTC evaluated these materials by first conducting a materials characterization of all eight samples. Then, based on those results and discussions with St. Mary's Pressed Metals, two samples were selected for powder consolidation and mechanical testing to determine if in fact the AMD residual materials were suitable for bearing applications. This presentation will discuss the conclusions from the evaluation.
