Reliable Mine Water Technology
Mine planning, permitting and operation require reliable water technology in all its aspects: water inflow, water use, water disposal and discharge, and water impact. Mine water evaluations are relied upon by mining companies, mine regulators and the public to determine whether the mine is technically feasible, optimally designed, financially sound, socially acceptable, and environmentally beni...
متن کاملWell water contaminated by acidic mine water from the Dabaoshan Mine, south China: chemistry and toxicity.
An investigation into well water quality was carried out in a rural area subject to irrigation with acidic mine water from the Guangdong Dabaoshan Mine, southern China. The results of water pH measurements from 112 wells in two different seasons suggest that the well water has been contaminated to varying degrees in the investigated Shangba floodplain (approximately 11km south of the Guangdong ...
متن کامل9 th INTERNATIONAL MINE WATER CONGRESS 141 Is mine water a source of hazardous gas ?
Most coal and coal bearing strata contain significant quantities of gases. These gases are either potentially explosive in critical concentrations when mixed with air, others are toxic. Gases found in a mine are almost certainly a mixture of atmospheric air, inert gases, water vapour and one or more of the following: oxygen, carbon monoxide, methane, hydrogen sulphide, hydrogen and nitrous oxid...
متن کاملUsing microbes and wastewater to desalinate water.
The technology is based on microbial fuel cells (MFCs), which use microorganisms as catalysts to convert chemical energy to electrical energy. The paper’s authors, including Bruce Logan of Pennsylvania State University and Xiaoxin Cao of Tsinghua University (China), are among the small group of researchers worldwide trying to improve MFCs—or bioelectrochemical systems, as they are beginning to ...
متن کاملAn insulator-based (electrodeless) dielectrophoretic concentrator for microbes in water.
Dielectrophoresis (DEP), the motion of a particle caused by an applied electric field gradient, can concentrate microorganisms non-destructively. In insulator-based dielectrophoresis (iDEP) insulating microstructures produce non-uniform electric fields to drive DEP in microsystems. This article describes the performance of an iDEP device in removing and concentrating bacterial cells, spores and...
