In this study, the flotation of converter slag was attempted. When this was unsuccessful, a sulfurization process developed in the previous studies was used. As a result of this process, a new surface forms on the converter slag particles and flotation experiments were carried out using these samples [1921]. As seen in the previous studies, successful results cannot be obtained by direct ...

Trithiocarbonates for PGM flotation by Vos*, Davidtz†, and Miller‡ Synopsis Small replacements of C12trithiocarbonate (C12TTC) for dithiocarbonate (DTC)/dithiophosphate (DTP) in a reagent suite for the flotation of platinum group metals (PGM) have significantly improved the rejection of gangue. Coupled to this is an ...
Copper Flotation From Converter Slag. The ore may be of the type known as Upper Group 2 UG2 which has a chromite matrix Instead the ore may be a mixture of the UG2 ore and a Merensky ore which contains chromite levels of less than 1 by mass While the process can be used for any chromite content it is envisaged that the process will usually be used for treatment of PGM containing ores having a ...
Slag is fed from the silo to a ball mill with a closedcircuit cyclone to achieve a tank cell flotation feed with a particle size of 60 to 75% passing 75 µm. The design mill feed rate is 100 t/h, resulting in a residence time of approximately 13 minutes in the flotation circuit. .

Recovery of platinum group metals (PGM) from flotation concentrates is currently achieved by energyintensive smelting processes that are highly susceptible to deleterious constituents, such as chromite, in the feed concentrate. Given the current rapid increase in energy costs over the recent past and forecast in future years, as well as the increasing chromite content of smelter feeds due to ...
Copper Flotation From Converter Slagsflotation Machine. Copper Flotation From Converter Slags S Lag Crushing. Leaching of copper and zinc from copper converter slag over 15 mt of dumped slags including converter slag flotation tailings which contain up to 6000 t copper and 60000 t zinc are produced yearly by the coppersmelting plants of the ural mining and metallurgical company ummc .
Flotation Of Pgm Converter Slag. Copper converter slag, such as resmelting or flotation, are effective for recovering the copper only Biswas amp Davenport 1994. The cobalt in converter slag, however, remains in resmelting slag or flotation tailings, and eventually gets lost with their disposal. More Details . Improving Beneficiation Of Copper And Iron From. Approximately 12 .
flotation of pgm converter slag The second route was flotation of the slags roasting of the flotation tailings with pyrite and leaching The second route was found to be suitable for the treatment of the copper slag studied In the flotation step a copper concentrate containing approximately 11 Cu was produced with a 77 recovery while 93 of the cobalt stayed in the .
58% of world PGM production takes place in South Africa1 not only for ore haulage but also to drive ... Wet chemical treatment known as froth flotation produces a concentrate which is dried and smelted in an electric furnace at temperatures over 1,500°C. A matte containing the valuable metals is transferred to converters to remove iron and sulphur. PGMs are then separated from the base metals ...
to low matte falls of PGMconcentrated furnace matte, which in turn lowers the total tons of fayalitic slag formed during converting and the commensurate amount of SO2 being formed. The smaller amounts of furnace matte, converter slag, and offgas do not warrant investment in continuous converting (Ausmelt/Isasmelt), slag cleaning furnaces, or

SEM imaging of a slag sample revealed few or no metal prills entrained. The FeO content in the initial concentrate charge was then increased by adding 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 Easterns ...
· Slag from converting, especially from the period of copper blowing, is typically inhomogeneous with significant amounts of suspended matte and metallic copper. To achieve the technological exploitation of copper in the level of % to blister in processing concentrate by using autogenous flash smelting technology, it is necessary to process the slag generated in the process of .
flotation of pgm converter slag. In other cases the slag is granulated, and subjected to milling and flotation; it is also possible to introduce the slag into a slagcleaning furnace. Breaking the recycle loop, by not returning the converter slag to the furnace, is rather attractive, as the quantity of PGMs locked up in this loop can represent a large financial price. .

sulphides are removed in the ACP converter. A slagcleaning furnace treats gangue from the converter, while a slag milling and flotation circuit treats the slag from the electric furnaces. The concentrate handling section currently treats around 72 000 t of wet concentrate per month. The electric furnaces smelt between 42 000 and 60 000 t
2Recovery of Copper and Cobalt from Converter Slag with a . Key words: Converter slag, flotation, copper, cobalt, sulphurization. 1. Introduction Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that around 4 million tons of slag are disposed every year and another 40 to 45 million tons are historically cumulated [1].

In addition, a similar flotation response w as slag resistance, which increases slag realized w ith onethird of the current depressant dosage. temperatures. This will increase During a preliminary plant trial on underground UG2 ore, the refractory wear and power consumption. initial rougher concentrates w ere characterized by higher PGM Merensky concentrate contains far less concentrate ...
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.
