· The converter slag from a smeltery in Daye contains % copper. The floatability of copper has a significant influence on the flotation of converter slag. Flotation tests, contact angle tests and FTIR were conducted to assess the influences of pH and different flotation concentrators on its hydrophobic process, mechanism and flotation.
tailings, and converter slag. The campaigns demonstrated the robustness and versatility of the process, and proved that it is possible to sustainably produce a PGMcontaining alloy and discardable slags containing an average of less than g/t of PGMs over the entire campaign.
grade concentrates, converter slag, and revert tailings) have been treated successfully at power levels of up to MW in a 3 m DC arc furnace, thereby demonstrating the robustness and versatility of the process, and proving that it is possible to sustainably produce PGMcontaining alloy and discardable slag from the DC furnace operation.
Lead and zinc slag Waste material PGM slag FeCr slag FeMn slag FeNi slag Others Figur e 9 illustrates a cross section of three possible test set ups for the laboratory tests. The small test rig allowed to run the process in conventional AC, conventional AC with coke layer and in DCmode.
· Following successful trials, in mid2016 Northam contracted us for the basic engineering of a new dry granulation system for converting slag. This required Hatch to design new equipment suitable for use with platinum group metals (PGM) slag and entrained matte, which, based on our experience in this sector, needed to be different than what had been previously implemented for steelmaking slag.
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
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.
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
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.
I claim: 1. A method of treating dore slag which comprises the steps of grinding the slag, mixing the obtained pulp with water to form a slurry, adding a suitable collector to the slurry for selective flotation of precious metals, adding a suitable frother, aerating the slurry to produce a precious metals concentrate in the form of a froth on top of the slurry, and separating said concentrate ...
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.
The chemical components, dissemination characteristics and flotation behaviour of copper slag have been investigated through chemical analysis, Xray powder diffraction (XRD), electron microscopeand flotation tests. These results show that the converter copper slag from Hubei, China, is refractory resource owing to its complex composition and mosaic relationship.
Mineralogical study of LD converter slag was carried out by means of microscopic and EPMA examinations and phosphorus was found to exist only in dicalcium silie as solid solution. This led to the study of separation of dicalcium silie from LD converter slag in order to remove phosphorus.
Crushed converter matte is milled and the PGM fraction is separated magnetically. ... metal refinery FLOTATION The separation of the valuable content from the ore takes place in flotation cells where reagents are added to an aerated slurry to produce highgrade PGMbearing concentrate ... Converter slag is reduced in an electric
Silica is then added to the converter to flux iron oxide and any excess soda; this slag is also poured off and the residual copper sulphide blown down to blister copper in the normal way. The blister copper is tapped into a ladle and poured directly into one of three small reverberatory furnaces. The copper is
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.
•Milling Flotation produce a Concentrate. •Smelting •The Smelters produce a "Furnace Matte". •Converting •The Converters produce a "Converter Matte". •Acid Plant •Treats SulfurRich Offgas from Converters •Refining •ase Metals Refinery produces Nickel, opper a "Dirty" PGM.
Spinel Removal from PGM Smelting Furnaces Barnes and Newall Heat Flow CC, Lanseria, ... modify the flotation process to minimise the amount of chrome contained in the ... situations where no converter slag is returned, as the lack of iron in the slag tends to result in a very siliceous slag.
PGM is similar to that of the slow floating PGM, and the unfloated PGM (Figure 2), indiing no clear "hierarchy" in mineral floatability. This is consistent with similar studies on the Lac des Iles circuit (1) Figure 2: Composition of fastfloating, slowfloating and unfloated PGM by mineral type However, largely, the PGM are finely ...
The effects of adjusting technological conditions on the phosphorous enrichment of adjusted converter slag were investigated. The results showed that the phosphorus could be effectively enriched to 2CaO · SiO2 and 2CaO · SiO23CaO · P2O5 solid solution (SS, namely phosphorusrich phase) to be formed with the decreasing of basicity and cooling rate.
