The adsorption characteristics of precious and base metals on four different ion-exchange resins
(Stellenbosch : Stellenbosch University, 2000-12)ENGLISH ABSTRACT: Adsorption tests were conducted with four different ion-exchange resins to determine the equilibrium adsorption of a range of precious and base metals. The adsorption characteristics were determined ... -
Adsorptive separations in the production of neutral wine alcohol
(Stellenbosch : Stellenbosch University, 2002-03)ENGLISH ABSTRACT: This study describes the design, construction, complete industrialisation and operation of a dual bed vacuum swing adsorption (VSA) demonstration plant, which operates at atmospheric and sub-atmospheric ... -
Advantages associated with the implementation and integration of environmental management systems in small manufacturing businesses
(Stellenbosch : Stellenbosch University, 2003-12)ENGLISH ABSTRACT: TheSouthAfrican economy islargely dependant on small enterprisesas a valuable source of job creation, gross domestic product as well as product development and innovation, However, unfortunately ... -
Aerosol synthesis of ceramic particles by seed growth : analysis of process constraints
(Stellenbosch : Stellenbosch University, 2002-04)ENGLISH ABSTRACT: Aerosol synthesis involves the formation of condensable product species by gas-phase reaction, and the simultaneous growth of particles by coagulation. For the production of ceramic particles, reaction ... -
Alkaline polyol fractionation of sugarcane bagasse and eucalyptus grandis into feedstock for value added chemicals and materials
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH SUMMARY: The main components of lignocellulosic biomass cellulose, hemicellulose and lignin are feedstock for chemical and material manufacturing processes. Integrated biorefinery processes incorporate the production ... -
Ammonium thiosulphate leaching of gold from printed circuit board waste
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH SUMMARY: Technological innovation leads to a reduced lifespan of older electrical and electronic equipment, which in turn leads to the generation of vast quantities of electronic waste (e-waste). The recycling of ... -
Analysis and modelling of mining induced seismicity
(Stellenbosch : University of Stellenbosch, 2006-12)Earthquakes and other seismic events are known to have catastrophic effects on people and property. These large-scale events are almost always preceded by smallerscale seismic events called precursors, such as tremors ... -
Analysis of process data with singular spectrum methods
(Stellenbosch : University of Stellenbosch, 2003-12)ENGLISH ABSTRACT: The analysis of process data obtained from chemical and metallurgical engineering systems is a crucial aspect of the operating of any process, as information extracted from the data is used for control ... -
Antimicrobial lipopeptide production by Bacillus spp. for post-harvest biocontrol
(Stellenbosch : Stellenbosch University, 2014-12)ENGLISH ABSTRACT: As overpopulation threatens the world’s ability to feed itself, food has become an invaluable resource. Unfortunately, almost a third of the food produced for human consumption is lost annually. Pests ... -
The applicability of nanofiltration for the treatment and reuse of textile reactive dye effluent
(Water Research Commission, 2015)The main aim of the study was to test the feasibility of using nanofiltration (NF) processes for the treatment of reactive dyebath effluents from the textile industry, in order to recover the water and chemicals (salts) ... -
The application of activated carbon for the adsorption and elution of platinum group metals from dilute cyanide leach solutions
(Southern African Institute of Mining and Metallurgy, 2013)ENGLISH ABSTRACT: The research presented in this paper investigated the practical aspects of the recovery of platinum group metals (PGMs) from a dilute cyanide leach solution containing base metals, in a manner similar to ... -

Application of membrane technology for purifying tyre derived oil
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH SUMMARY: Tyre derived oil (TDO) is an abundant liquid product obtained after pyrolysis of waste tyre. It contains a complex mixture of C6–C24 organic compounds of various classes such as paraffins, olefins, aromatics, ... -
Application of membrane technology in a base metal refinery
(Southern African Institute of Mining and Metallurgy, 2013)Nanofiltration (NF) has attracted much attention over the past few years due to the reduced energy consumption compared to reverse osmosis (RO) and better separation performance compared to ultrafiltration (UF). Although ... -
Arabinoxylan as partial flour replacer: The effect on bread properties and economics of bread making
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Wheat bran, used for animal feed, is a good candidate for production of higher value products such as arabinoxylan (AX). Extracted AX holds potential as a partial flour replacer in the bread making industry. ... -
