Activity-based risk management for the acquisition of electronic mine safety equipment
(SAIMM, 2017)A new approach is proposed to perform relativistic comparisons between alternative operational risk management solutions by taking into account the impact of each operational activity on overall system performance. ... -
As educators of teachers, where and when do our responsibilities end?
(Kamla Raj Enterprises, 2015)Quality education is a basic right of every South African learner, though despite many positive changes in the country since 1994, the legacy of low–quality education in many historically disadvantaged parts of the school ... -
DFT modelling of tantalum pentafluoride extraction with phosphorus-based extractants – a molecular dynamics study
(Elsevier, 2019)Solvent extraction (SX) is a powerful method for both the separation and extraction of metals, resulting in high purity metals. The transition metals tantalum (Ta) and niobium (Nb) are of considerable significance, for ... -
A FEM model for microwave absorption and heat transfer in a microwave combination washer dryer
(IEEE, 2013)Applications for the use of microwaves reach far and wide in various industries. Commonly known is the use of microwaves to heat foodstuffs. Research and development conducted in the development of a microwave combination ... -
Hydrocyclone cut-size estimation using artificial neural networks
(Elsevier, 2016)The hydrocyclone is widely used throughout the mineral processing industry when working with slurries. It is either used for classifying, desliming or dewatering. Hydrocyclones are inexpensive, application-efficient and ... -
Molecular modelling of tantalum fluoride in sulphuric acid medium: a DFT study
(Elsevier, 2019)During the solvent extraction (SX) experiments of tantalum (Ta) and niobium (Nb), the aqueous phase consisted of tantalum- and niobium penta-fluoride (Ta(Nb)F5), water (H2O) and sulphuric acid (H2SO4), which was contacted ... -
Molecular modelling of tantalum penta-halides during hydrolysis and oxidation reactions
(Elsevier, 2016)The transition metals tantalum (Ta) and niobium (Nb), which are usually found together in nature, have similar chemical and physical properties, making their separation challenging. There are various methods available for ... -
A predictive model for a Wet-high-intensity-magnetic-separator (WHIMS) using artificial neural networks
(EARET, 2018)—Materials can be classified into three major categories based on the magnetic susceptibility thereof; the property governing the response of the material subjected to a magnetic field. Chromium has many uses in the ... -
Species composition of tetranychoid mites (Acari: Trombidiformes: Prostigmata: Tetranychoidea) in main landscapes of Tehran and modelling ecological niche of Tetranychoidea in main climates of Tehran Province, Iran
(Walter de Gruyter GmbH, 2016)Tetranychoid communities from urban landscapes of Tehran area were compared in 2012. The landscapes covering two main climates of Tehran Province and the related regions were mostly planted with Ulmus, Platanus, Ficus and ... -
Trace element behaviour in the Sasol-Lurgi MK IV FBDB gasifier. Part 2. The semi-volatile elements: Cu, Mo, Ni and Zn
(Elsevier, 2009)Gasification is a coal conversion process that could be considered to be more amenable with regards to environmental impact factors when compared to combustion, as it provides minimum direct emission to the atmosphere due ...
