Evaluation of Quicklime Dose, Stirring Speed, and Reaction Time for Coal Mine Acid Water Treatment
Jurnal Ilmu LingkunganBackground: If not properly managed, coal mining activities can lead to significant damage to the earth's surface. Acid water, often referred to as acid mine drainage, typically forms during both active and inactive mining operations.

Advanced Functional Materials, EarlyView.Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

The evolution of mine waters quality at the locality of Smolník [PDF]
Acta Montanistica Slovaca, 2006 At the present time, acid mine drainage (AMD) is considered to be one of the worst environmental problems associated with the mining activity. AMD originates as a result of natural oxidation of sulphide minerals, mainly pyrite when exposed to the ...

Advanced Functional Materials, EarlyView.A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Application of Flowback Water and GOPS on the Prevention of Acid Mine Drainage in the Mather Mine [PDF]
, 2013 Acid mine drainage (AMD) is an environmental pollutant that degrades water bodies and harms aquatic life. In the Appalachian Mountains of the eastern U.S., over 7,500 miles of streams are impacted by AMD.
