(Maney Publishing, 2014-09)Previous work showed that manganese ore reduction rates are strongly influenced by the extent of slag phase formation. In this work, the effect of ore composition on slag formation during manganese oxide reduction was ...
-
(Springer, 2015-01)Please read abstract in the article.
-
(Southern African Institute of Mining and Metallurgy, 2014-07)Owing to decreasing high-grade ore reserves, there is a need for better understanding of the jigging process to improve the recovery efficiency of finer, lower grade material. The use of positron emission particle ...
-
(Springer, 2014-10)The purpose of this study was to determine the kinetics of the dissolution of a uranium residue in ammonium carbonate media. The residue is generated in the production of medical isotopes. The effects of parameters, such ...
-
(Southern African Institute of Mining and Metallurgy, 2014-04)The ferromanganese industry is under pressure to deal with the slag arising from the production of ferromanganese, which is discarded in landfills or slag heaps. This material poses an environmental and health risk to ...
-
(Southern African Institute of Mining and Metallurgy, 2014-04)Steel is produced in a basic oxygen furnace from hot metal obtained from a blast furnace. A sintered iron ore with good hightemperature properties (strength and permeability) should be used as feed to the blast furnace. ...
-
(Southern African Institute of Mining and Metallurgy, 2014-04)The postulation that primary platinum group metal (PGM) matte will chemically react with magnesia-chrome bricks when temperatures exceed 1500°C was tested. Magnesia-chrome brick samples were heated in contact with matte ...
-
(Emerald, 2013)PURPOSE – This investigation aims to find the degree of passivation required to completely inhibit the stress corrosion cracking of carbon steel exposed to CO-CO2-H2O environments. DESIGN / METHODOLOGY / APPROACH – A516 ...
-
(2014-08-20)Although the austenitic stainless steels 304 and 321 are often treated nominally as equivalents in their hot rolling characteristics, the question remains whether any subtle differences between the two allow ...
-
(Elsevier, 2014-03)Kimberlite material is one of the primary sources of diamonds. Accelerated weathering that leads to a physical breakdown of the material over a short period of time has possible benefits in diamond processing such as ...
-
(Elsevier, 2013-04)The separation of iron ore in a prototype batch jig separator developed by Mintek in South Africa, referred to as the Mineral Density Separator (MDS), can separate ore samples into multiple bulk density fractions, ...
-
(Elsevier, 2014-05)Although the austenitic stainless steels 304 and 321 are often treated nominally as equivalents in their hot rolling characteristics, the question remains whether any subtle differences between the two allow further ...
-
(Southern African Institute of Mining and Metallurgy, 2013-04)Ti-64, which accounts for more than 50% of the worldwide titanium tonnage, has found commercial importance in industries requiring components with high specific strength and resistance to corrosion. Investment casting ...
-
(Elsevier, 2013-11)The production of Platinum Group Metals (PGMs) normally entails the smelting of PGM flotation concentrates, converting of the furnace matte and removal of the bulk of the Ni, Cu, Co, S and Fe through atmospheric and ...
-
(Southern African Institute of Mining and Metallurgy, 2013-04)The aim of the project was to experimentally determine the coefficient of restitution, and static and rolling friction of Eskomgrade coal for discrete element modelling (DEM). These parameters will be used in further ...
-
(Elsevier, 2013-07)The lattice parameter change of SiC in TRISO particles prepared by chemical vapour deposition (CVD) was measured using high temperature X-ray diffraction, across a temperature range of 25–1400 C. Al2O3 was used as the ...
-
Reactivity between carbon cathode materials and electrolyte based on industrial and laboratory data (Elsevier, 2013-07)Interaction between electrolyte and carbon cathodes during the electrolytic production of aluminium decreases cell life. This paper describes the interaction between carbon cathode materials and electrolyte, based on ...
-
(Southern African Institute of Mining and Metallurgy, 2012-04)All industrial processes are economically driven, resulting in the ever increasing need for process optimization in order to stay competitive and profitable. Numerous models has been published depicting the optimization ...
-
(Southern African Institute of Mining and Metallurgy, 2012-03)In this study the applicability of a batch press to predict the energy consumption and particle size distributions for medium-pressure roller presses was investigated. The relationships between energy consumption, feed ...
-
(Southern African Institute of Mining and Metallurgy, 2012-04)The kinetic leaching behaviour of a low-grade surface gold ore and a high-grade reef ore were evaluated to determine the achievable gold recovery from these ores and particularly mixtures of these ores. The reef ore ...
