A practical approach to testing for acid mine drainage in the mine planning and approval process

, 1989
Acid mine drainage is one of the biggest environmental issues facing mining companies today. Government agencies, the general public and mine owners require that potential for acid generation can be predicted and controlled with a high degree of ...

Combination of CaCO3 and Ca(OH)2 as agents for treatment acid mine drainage

MATEC Web of Conferences, 2017
Acid mine drainage (AMD) has characteristic very low pH solution and containing metal ions in high concentration. This paper presents the use of CaCO3, Ca(OH)2 and the combination of both to increase the pH and decreased the concentration of Fe and Mn ...

3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

Advanced Robotics Research, EarlyView.
This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...

Remote mine site acid rock drainage treatment

, 1998
As a part of the Mine Waste Technology Program (MWTP) a pilot-scale technology was tested for the remediation of acid mine drainage at a remote mine site. A remote mine site is one without infrastructure or power sources.

Pre‐Encoded IFN‐I Sensitivity Exacerbates Memory T Cell Senescence in Solid Tumors

Advanced Science, EarlyView.
Type I interferon (IFN‐I) signaling promotes p21‐dependent cell cycle arrest in senescent tumor‐specific memory T cells, resulting in poor proliferative responses and solid tumor regression during cancer vaccination. Conversely, IFNα/β receptor blockade reinvigorates T cell proliferation to regress solid tumors and is more effective with increasing ...

Role of oxygen transfer in acid mine drainage treatment [PDF]

"The U.S. Bureau of Mines formulated a new mathematical model to characterize iron oxidation. The new model is intended to replace the currently used model, recommended by the Environmental Protection Agency (EPA), for most acid mine drainage (AMD ...

FABA block medium for eucalyptus (Melaleuca cajuputi) seedling planting and acid mine drainage neutralization in artificial wetlands

Journal of Degraded and Mining Lands Management
Open-pit coal mining activities have an impact on environmental changes, one of which is the emergence of acid mine drainage. Acid mine drainage (AMD) arises from sulfide minerals that react with oxygen and water.
