Complete sulphate removal from neutralised acidic mine drainage with barium carbonate

Author: Swanepoel, H ; De Beer, Morris ; Liebenberg, L Date: Mar 2012 The most widespread method used for the treatment of acidic mine drainage (AMD) is neutralisation through the addition of lime to the effluent in order to raise the pH. As a result, dissolvedmetals precipitate as metal hydroxides while partial ... Read more
Integrated iron(II) oxidation and limestone neutralisation of acid mine water

Author: Maree, JP ; Strydom, WF ; De Beer, Morris Date: 1999 Volumetric iron (II) oxidation rates exceeding 100 g/(l.d) were achieved by dosing powdered limestone to a bio-reactor treating artificial acid mine water. Neutralisation and partial sulphate removal were achieved as well. The rate is highly ... Read more
Recovery of water from acid mine drainage

Author: Mulopo, J ; Motaung, SR ; Mashego, M ; Moalusi, M Date: Oct 2010 The reaction rate of sulphate removal from acid mine drainage using barium carbonate was studied for various pH, calcium concentration, and BaCO3/SO42 feed ratios in batch studies. Process synthesis concepts were used to investigate the ... Read more
Sulphate removal from industrial effluents through barium sulphate precipitation

Author: Swanepoel, H Date: Nov 2011 The pollution of South Africa’s water resources puts a strain on an already stressed natural resource. One of the main pollution sources is industrial effluents such as acid mine drainage (AMD) and other mining effluents. These effluents ... Read more
Volatile fatty acid formation and utilization in anaerobic sulphidogenic batch reactors

Author: Greben, HA ; Baloyi, LJ ; Eisberg, R ; Joubert, LM ; Botha, A ; Venter, SN Date: May 2006 Acid Mine Drainage (AMD) needs to be treated, before it is recharged in rivers and dams. The biological treatment of AMD can be applied using degradation products of cellulose, for example Volatile Fatty Acids as carbon sources. The aim of ... Read more
