Effect of cuprous cyanide, dry and wet milling on the selective flotation of galena and sphalerite (Elsevier, 2006-01)Batch flotation tests of a lead–zinc sulphide composite ore from the Rosh Pinah Mine have been carried out at pH 8.5 in the presence of copper cyanide complexes. These copper cyanide complexes are often found in the recycled ...
-
(Elsevier, 2007-03)The Rosh Pinah orebody is a complex lead–zinc sulphide system with pyrite gangue and minor amounts of copper. Laboratory scale milling and flotation testing of ore samples taken from this operation was performed. Different ...
-
(Elsevier, 2007-05)The capacity of dense medium cyclones is often restricted by the solids-carrying capacity of the underflow, referred to as spigot capacity. Cyclone manufacturers normally recommend the spigot capacity for a cyclone of a ...

(Elsevier, 2007-05)The hydrolysis of ferric iron at elevated temperatures and pH values between 1.5 and 3.5 was characterized by determining the stability regions for schwertmannite, 6-line ferrihydrite and 2-line ferrihydrite, and linking ...

(Elsevier, 2008)In a hot rolled Nb–Ti and a Nb–Ti–0.09%Mo micro-alloyed steel, the ratio of yield strength to tensile strength (YS/UTS) was found to be a function of the microstructure and cooling rate in those tests where no coiling ...
-
(Elsevier, 2008)Froth flotation for beneficiation of printed circuit board comminution fines was investigated in this work, via reverse flotation under a scheme described as natural hydrophobic response. With no reagents, the scheme ...
-
(Elsevier, 2008-03)Dithiocarbonates (xanthates) have been the most widely used collectors in sulphide mineral flotation. More recently, research has resulted in the use of trithiocarbonate (TTC) collectors. The present study focuses on the ...
-
(The South African Institute of Mining and Metallurgy, 2008-04)The world mineral industry has over the years experienced growth in the production of nickel (Ni) due to its use not only in the catalytic industry but mainly also its demand in the stainless steel production industry. ...

Control of the grain size distribution of the raw material mixture in the production of iron sinter (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 ...
-
(Elsevier, 2008-08)Neither a higher hardness nor higher mechanical properties (yield strength, ultimate tensile strength, impact energy, and %elongation) appear to be exclusive or even reliable criteria for predicting the ballistic performance ...
-
(Maney, 2009)Several electric furnaces, which are used to melt down partially prereduced vanadiferous magnetite at Highveld Steel and Vanadium, have recently been converted from submerged arc furnaces (SAFs) to open slag bath furnaces ...
-
(Maney, 2009)Packed beds of coal and iron ore (mostly in the size range 425–850 mm) were heated by thermal radiation to the bed surface, to test possible rate determining steps, the effect of coal volatiles, and whether the previously ...
-
(Maney, 2009)An experimental configuration was developed to quantify the rate of heat transfer into an iron ore– carbon mixture during one-dimensional radiative heating. Repeatability and accuracy were evaluated by comparing the results ...
-
Characteristics of martensite as a function of the Ms temperature in low-carbon armour steel plates (Elsevier, 2009)The microstructure, morphology, crystal structure and surface relief of martensite in a number of experimental armour steel plates with different Ms temperatures were analysed. Atomic force microscopy, thin foil transmission ...
-
(Maney, 2009)Cracking occurs in the first step of gaseous reduction of hematite iron ore, to magnetite, and can lead to the formation of fine material, with deleterious effects on operation of shaft furnaces. To study this, samples of ...
-
(Maney, 2009-03)The microstructures and mechanical properties of strontium modified semisolid metal high pressure die cast A356 alloy are presented. The alloy A356-F (as cast) has a globular primary grain structure containing a fine ...
