Assessment of dermal exposure and skin condition of refinery workers exposed to selected metals
(North-West University, 2010)Aims and objectives: The research aims and objectives of this thesis were: (i) to review literature pertaining to different dermal exposure assessment methods; (ii) to assess dermal exposure of refinery workers to ... -
Assessment of dermal exposure and skin condition of workers exposed to nickel at a South African base metal refinery
(Oxford Univ Press, 2010)Objectives: The objectives of this study were to assess dermal exposure of cell workers to nickel at a South African base metal refinery and to characterize their skin condition by measuring the skin hydration and trans ... -
The cobalt-nickel pertraction refinery to process recycled spent catalysts leach solutions
(North-West University (South Africa), 2019)Over the last two years, the cobalt (Co) price has increased considerably. The observed increase can be attributed to the increase in demand of lithium-ion batteries (LIBs) of which Co forms an integral part. As a consequence ... -
Comparison of airborne particulate exposure in two platinum refining process areas
(North-West University, 2010)The aims and objectives: The aims and objectives of this study were to characterize and compare the airborne particulate matter in the tankhouse and crusher areas of a base metal refinery sampled with two separate methods, ... -
Exposure of workers to nickel, copper and lead in a base metal recovery plant and laboratory
(North-West University, 2011)Objectives: The objectives of this study were to establish the extent of dermal and respiratory exposure at selected locations at a South African platinum mine. The study included exposure to lead oxide fumes in an assay ... -
Nikkel-bevattende bimetaal-nanodeeltjies as katalisatore vir elektrochemiese watersplyting
(North-West University (South Africa), 2023)The hydrogen evolution reaction (HER) can occur in an acidic or alkaline medium. The alkaline HER is very important for water-splitting electrolysers because contamination of H2 and corrosion of the electrolysers and ... -
Optimisation of PtxNiyAlz ratios as thin film electrocatalysts for the oxygen evolution reaction (OER) in alkaline medium
(North-West University (South Africa), 2020)The world is currently reliant on energy sources such as oil, coal and gas (all fossil fuels) for the supply of the global growing energy demand. However, these fossil fuels are diminishing and have drawbacks such as the ... -
Senecio conrathii N.E.Br. (Asteraceae), a new hyperaccumulator of nickel from serpentinite outcrops of the Barberton Greenstone Belt, South Africa
(ESJ, 2018)Five nickel hyperaccumulators belonging to the Asteraceae are known from ultramafic outcrops in South Africa. Phytoremediation applications of the known hyperaccumulators in the Asteraceae, such as the indigenous Berkheya ... -
The South African industry use of Mössbauer spectroscopy to solve operational problems
(Springer, 2014)South Africa is a country that is very rich in mineral resources but the use of Mössbauer spectroscopy to solve operational industrial problems is however very limited. In the Bushveld Igneous Complex the main minerals ...
