Hydrothermal synthesis and optimisation of zeolite Na-P1 from South African coal fly ash
(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. ...
Synthesis and electrochemical characterisation of conducting polyaniline-fly ash matrix composites
(2005)
The aim of this study was to produce useful composite materials from fly ash, a major waste product of coal combustion from power plants. Polyaniline-fly ash (PANI-FA) composites were prepared by in situ polymerisation of ...
CO2 sequestration using brine impacted fly fish
(University of the Western Cape, 2009)
It was hypothesized that South African FA and brine could sequester CO2 through mineral carbonation. A statistical approach was undertaken to optimize the % CaCO3 formed from FA/brine/CO2 interaction with input parameters ...
Removal of sulphates from South African mine water using coal fly ash
(University of the Western Cape, 2009)
This study evaluated SO4 2- removal from circumneutral mine water (CMW) collected from Middleburg coal mine using coal FA collected from Hendrina power station. The following parameters were investigated: the effect of the ...
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 ...
