Re-use of South African fly ash for CO2 capture and brine remediation.
(University of the Western Cape, 2013)
Coal combustion accounts for 95% of electricity generation in South Africa while globally coal combustion for energy generation stands at 42%. It has been predicted that coal utilization for energy generation will continue ...
Active neutralisation and amelioration of acid mine drainage with fly ash
(University of the Western Cape, 2009)
Due to the constraints being placed on water resources and a drive for major industries to recycle waste water, improved and cheaper water treatment technologies are being investigated. During mining, pyrite (FeS2), a ...
Hydrothermal synthesis and optimisation of zeolite Na-Pl from South African coal fly ash
(University of Western Cape, 2009)
Millions of tonnes of fly ash are generated worldwide every year to satisfy the large demand for
energy. Management of this fly ash has been a concern and various approaches for its beneficial
use have been investigated. ...
Chemical compositions and leaching behaviour of some South African fly ashe
(University of the Western Cape, 2008)
Fly ash is the most abundant of the waste materials generated from coal combustion in coal-fired power stations. South Africa uses more than 100 million tonnes of low grade bituminous coal annually to produce cheap electricity ...
Removal of sulphates from South African mine water using coal fly ash
(University of the Western Cape, 2009)
South African power stations generate large amounts of highly alkaline fly ash (FA). This waste product has a serious impact on the environment. Acid mine drainage (AMD) is another environmental problem associated with ...
