and converter slag which contain % Cu and 28% Cu, respectively. The following three methods are generally utilized for recovering the copper from these slags on an industrial scale: (i) recycling of the converter slag to the smelting furnace, (ii) cleaning of smelting and/or converter slags in electric furnaces and (iii) flotation.
collector in PGM flotation where chromite in the concentrate is a problem and as a collector to enhance recovery of coarse and fine copper in slag milling. Flottec 300 series products can be used alone or in conjunction with other collectors but may require additional frother. Xanthate Esters are very selective collectors for copper minerals.
consequence of converter slag recycle to the primary furnaces is the increase in the electrical conductivity of the slag due to the higher concentration of FeO and magnetite in the slag, which can allow for electronic conduction in addition to ionic conduction (Hundermark et al., 2003).
A process for separating platinum group metals (PGM's) from various feedstock materials, is disclosed, wherein a plasma arc flame is employed to produce a superheated puddle on the surface of a slag layer to accelerate the association of platinum group metals with a collector material and formation of a recoverable layer of platinum group metals and collector material.
· Comparison of flotation results with primary PGM ore. The EAF slag has shown interesting flotation behaviour, allowing for enriching PGMs from a siliceous matrix. Here, the content of PGMs in the slag is roughly tenfold the minimum concentration of .
These float to the surface and are removed as a soapy froth. The pgm content of this flotation concentrate varies between 100 and 1,000 grams per tonne. After being dried, the concentrate is smelted in an electric furnace at temperatures which can exceed 1,500ºC.
PeirceSmith converter slag in order to decrease the slag viscosity and further increase PGM recovery. A test was conducted with the addition of 10 kg converter slag per 100 kg A test was conducted with the addition of 10 kg converter slag per 100 kg. impacts of slag mill and flotation

junior PGM producers have sold their flotation concentrates to the major producers who have utilized ... slag cleaning, gas cleaning, and converting of the furnace matte also have to be added to
· Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basicoxygenfurnace (BOF) steelmaking, electricarcfurnace (EAF) steelmaking, and ladlefurnace steel refining processes. The mineralogical and morphological properties of BOF and electricarcfurnaceladle [EAF(L)] slag ...

TRITHIOCARBONATES FOR PGM FLOTATION 169 Introduction An increase in the beneficiation of UG2 ore is central to Impala Platinum's strategic plan for increasing its platinum ... of the matte/slag separation due to an increase in slag viscosity Ł High quantities of chrome also increase slag resistance, which increases slag temperatures.
The TSL PGM converter was chosen for the reasons that the Ausmelt/Isasmelt TSL smelting furnaces are highly productive flexible smelting and converting ... Table 413: Converter slag quality for simulation ..... 88 Table 414: Calculation matrix for simulation ...
The following Table 4 shows the converter slag analysis. The converter slag is sent back to the furnace slag (auxiliary smelter) to attempt the recovery of any possible PGM concentration within the slag.

FLOTATION. The separation of ... Converter slag is reduced in an electric furnace to recover PGMs and base metals for recycling back to the converter. ... Crushed converter matte is milled and the PGM fraction is separated magnetically. This is pressure leached to yield a .
concentrate. In order to decrease slag viscosity and to enhance PGM recovery, the FeO content of the Easterns concentrate was increased with the addition of 10 kg converter slag per 100 kg concentrate. Ir and Pd recoveries were increased to about 95%, while Pt recovery was around 70%. On the basis of these results an optimum feed ratio between
· Copper Flotation From Converter Slags. Copper Flotation From Converter Slags. Following three methods are generally utilized for recovering the copper from these slags on an industrial scale i recycling of the converter slag to the smelting furnace, ii cleaning of smelting andor converter slags in electric furnaces and iii copper and sulphide copper present in these slags ...
with molten slag floating on its upper surface. These two materials are separated using a , the molten iron being channelled to a holding vessel and the molten slag to a point where it is to be treated further and according to treatment the slag is classified.
Leaching of copper and zinc from copper . · Over Mt of dumped slags, including converter slag flotation tailings, which contain up to 6000 t copper and 60,000 t zinc, are produced yearly by the coppersmelting plants of the Ural Mining and Metallurgical Company (UMMC) alone.
ter usage, PGM bearing ore flotation circuits make use of recycled process water. Howev er, the chemistry of recycled process water may alter the performance of the flotation system. It is therefore required to understand the effects of these elements on the flotation process.
· Consequently, flotation was attempted to recycle Cu in slag containing copper sulphide components. Three key factors affecting flotation were ascertained, namely, grinding fineness, the collector and the pH value, while the recovery of Cu estimated by ICP and XRF. Copper concentrate grading at with % Cu recovery was obtained, in the ...
