Control of the grain size distribution of the raw material mixture in the production of iron sinter Lwamba, E.; Garbers-Craig, Andrie Mariana (Southern African Institute of Mining and Metallurgy, 2008-05)The aim of this study was to examine the effect of grain size distribution control of the raw material mixture on the permeability of the green sinter bed and the properties of the produced sinter. This was achieved by ...

Rambiyana, R.I.; Den Hoed, P.; Garbers-Craig, Andrie Mariana (Southern African Institute of Mining and Metallurgy, 2015-06)Four sulphide minerals – pyrite (FeS2), pyrrhotite (Fe1–xS), pentlandite ([Ni,Fe]9S8), and chalcopyrite (CuFeS2) – contain the base metals and most of the iron in concentrates of platinum group metals (PGMs). In ...

Influence of a carboxymethyl cellulose (CMC) binder on the mechanical properties of iron ore pellets Van der Merwe, M.C.J.; Garbers-Craig, Andrie Mariana (Southern African Institute of Mining and Metallurgy, 2017-04)Carboxymethyl cellulose is an organic binder used in the iron ore pelletizing industry. The basic principles of how carboxymethyl cellulose (CMC) solutions behave during the pelletizing process and how these principles ...

Kalenga, M.K.; Garbers-Craig, Andrie Mariana (Southern African Institute of Mining and Metallurgy, 2010-08)The influence of varying amounts of magnesia, silica, and alumina in iron ore sinter on its mineralogy, reducibility index (RI), reduction disintegration index (RDI), physical breakdown (AI and TI), and production properties ...
-
Steenkamp, H.; Garbers-Craig, Andrie Mariana (Southern African Institute of Mining and Metallurgy, 2020-06)Sulphur driven off from the sulphides in the black top of PGM smelters has in past years caused failure of copper coolers. When the magnesia-chromite bricks in the smelter were replaced with graphite blocks, however, ...
-
Swanepoel, Stefan; Garbers-Craig, Andrie Mariana (Elsevier, 2023-11)The oxidation of chromite pellets prior to smelting in a submerged arc furnace is key to ensuring that maximum benefit can be derived in the subsequent smelting step. Oxidized pellet feed material reduces operating costs ...

Du Toit, J.; Cromarty, Robert Douglas; Garbers-Craig, Andrie Mariana (Southern African Institute of Mining and Metallurgy, 2016-04)Penetration of matte into tap-hole bricks causes detrimental refractory wear, which can lead to furnace breakouts. The ability of the tap-hole clay to form a protective layer on the brick, thereby limiting matte ...

Reactivity between carbon cathode materials and electrolyte based on industrial and laboratory data Chauke, Levy; Garbers-Craig, Andrie Mariana (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 ...

Nyembwe, Mutombo Alainch; Cromarty, Robert Douglas; Garbers-Craig, Andrie Mariana (Elsevier, 2019-01)The sinter process converts mixtures of iron ore, iron ore fines and fluxes into a fused aggregate (sinter) that is used as burden material in the blast furnace. The rate of this process is predicted by measuring the ...

Lange, Matthias; Garbers-Craig, Andrie Mariana; Cromarty, Robert Douglas (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 ...
