-
(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, ...
-
(Southern African Institute of Mining and Metallurgy, 2012-07)The ferrite-pearlite microstructure is the most popular microstructure for alloys used in structural applications, including railway wagon wheels. These alloys have been designed through alloying and thermomechanical processing ...
-
(Southern African Institute of Mining and Metallurgy, 2010-04)Zincor experienced significant losses of metallic zinc to dross during the melting of zinc cathode plates. In this study five factors affecting the formation of dross are identified from literature. Dross from both the ...
-
(Trans Tech Publications, 2019)l-Si-Mg casting alloys, such as Al-7Si-0.3Mg alloy A356, are heat treatable and can be precipitation hardened to the T6 temper condition. However, Al-Mg-Si casting alloys (5xx series) are generally not considered to be ...
-
(Springer, 2022-12)Please read abstract in the article.
-
(Southern African Institute of Mining and Metallurgy, 2009-06)The use of SO2/air gas mixtures as an oxidant to precipitate Mn from Co(II) leach liquors was investigated. The effects of SO2/air ratio, pH and temperature on Mn precipitation were evaluated. It was found that the use of ...
-
(Maney Publishing, 2012-04)Within ilmenite smelters, the slag is at a temperature just above its liquidus (because the furnace operates with a slag freeze lining), and the metal bath is at a temperature which is approximately 150°C lower than the ...
-
(Elsevier, 2020-09)Please read abstract in the article.
-
(Elsevier, 2019-06)In this study, the iron-titanium-vanadium-oxygen (Fe-Ti-V-O) system in equilibrium with air was studied experimentally by high-temperature equilibration, quenching, scanning electron microscope and microprobe analysis ...
-
(Elsevier, 2018-12)Please read abstract in the article.
-
(Elsevier, 2018-12)The Ti-V-O system was studied experimentally from 700 °C to 1500 °C by high-temperature equilibration, quenching, scanning electron microscope and Energy-Dispersive X-Ray spectroscopy. The solubility of titanium in the ...
-
(Elsevier, 2018-08)The γ-Ti-45Al-2Nb-0.7Cr-0.3Si based intermetallic alloy was developed. Microstructure evolution of the as-cast and heat-treated alloy yielded the spheriodised and Widmanstätten laths. High temperature differential thermal ...
-
(Mary Ann Liebert, 2019-10)This article reports on an exceptional insight provided by nondestructive X-ray tomography of the same samples before and after laser shock peening (LSP). The porosity in two additively manufactured aluminum alloy (AlSi10Mg) ...
-
(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 ...
-
(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 ...

(Elsevier, 2023-02)Please read abstract in the article.
-
(IOP Publishing, 2019-11-09)The present study focused on preparation and characterization of 60Al-40V master alloy which was produced via aluminothermic process. The study assessed the production in order to provide the optimum Al requirement for ...
-
(Southern African Institute of Mining and Metallurgy, 2009-12)A brief overview is given of the issues regarding the processing of waste electrical and electronic equipment (WEEE). The printed circuit board component of WEEE is an exceptionally complex feed to possible recycling ...
-
(Southern African Institute of Mining and Metallurgy, 2009-12)Scrap printed circuit boards were selectively smelted at 1 200°C to produce a metallic alloy having three phases. These phases were identified as a lead-rich phase, a low tin content alpha bronze phase, and a high tin ...
-
(Southern African Institute of Mining and Metallurgy, 2020-05)The CSIR is developing a process to produce commercially pure (CP) Grade 4 titanium metal powder via direct metallothermic reduction of TiCl4. Crude titanium produced by this method is inevitably contaminated with unreacted ...
