Ferrochrome waste management : addressing current gaps
(North-West University (South Africa), Potchefstroom Campus, 2018)
Various chromium (Cr) compounds, Cr metal and/or Cr-containing alloys are used in modern
society. By volume the largest application for Cr is in the production of stainless steel, which
owes its corrosion resistance ...
Measurement of organic compounds in atmospheric aerosols collected at Welgegund, South Africa
(North-West University, 2018)
Atmospheric aerosols or particulate matter (PM) are a complex mixture of solid and liquid particulates suspended in the atmosphere that originate from natural and anthropogenic sources. These species influence climate ...
Factors influencing surface ozone variability over continental South Africa and implications for air quality and agriculture
(North-West University, 2018)
Extensive scientific research has been conducted on surface ozone (O3) concentrations over several decades in North America and Europe. Through these efforts, significant information is available on the role of chemistry, ...
Spatial and temporal deposition of selected biogeochemical important trace species in South Africa
(North-West University, 2018)
The concern of potential adverse environmental effects due to increased anthropogenic emissions to the atmosphere necessitates the need for long-term atmospheric deposition programmes. Wet and dry depositions of emitted ...

The impact of raw material selection on damring formation and pre-reduction during ferrochrome production
(North-West University, 2018)
Electricity consumption is the largest cost component in the production of ferrochrome (FeCr). Currently the pelletised chromite pre-reduction process (solid-state reduction of chromite) is the process option with the ...
