Summary of research paper published in Atmospheric Chemistry and Physics titled: Spatial, temporal and source contribution assessments of black carbon over the northern interior of South Africa
(NACA, 2017)
According to the latest assessment report of the
Intergovernmental Panel on Climate (IPCC), aerosol black
carbon (BC) is considered the second most ...
SEM image processing as an alternative method to determine chromite pre-reduction
(SAIMM, 2017)
The specific energy consumption (SEC) of the pelletized chromite prereduction
process is the lowest of all FeCr production processes
commercially applied. This process also eliminates the use of chromite ore
fines that ...
The effect of carbonaceous reductant selection on chromite pre-reduction
(Springer, 2017)
Ferrochrome (FeCr) production is an energy-intensive process. Currently, the pelletized
chromite pre-reduction process, also referred to as solid-state reduction of chromite, is most
likely the FeCr production process ...
Techno-economic feasibility of a preoxidation process to enhance prereduction of chromite
(SAIMM, 2017)
Ferrochrome (FeCr) is vital for the production of stainless and high-alloy
ferritic steels, since it is the only source of new Cr units. FeCr production is
an energy-intensive process. The pelletized chromite prereduction ...
Aqueous solubility of Cr(VI) compounds in ferrochrome bag filter dust and the implications thereof
(WRC, 2017)
The production of ferrochrome (FeCr) is a reducing process. However, it is impossible to completely exclude oxygen from all of the high-temperature production process steps, which may lead to unintentional formation of ...
Review of Cr(VI) environmental practices in the chromite mining and smelting industry: relevance to development of the Ring of Fire, Canada
(Elsevier, 2017)
During stainless steel production, new chromium units are obtained from ferrochrome, a relatively crude alloy produced from chromite ore. Large chromite reserves have recently been discovered in the so-called Ring of Fire, ...
