· 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 ...
The industrial PGMslag did not wet graphite, the contact angle between graphite and slag samples was greater than 90°. The industrial PGMslag was exposed to graphite using the crucible test method.
Flotation tailings from leadzinc mines and copper mines, fly ash from thermal power plants and metallurgical slag can be potentially used materials for this method. This paper presents the characterization of these materials from some localities in Serbia .
A flowsheet has been developed for the production of rich concentrates of precious and nonferrous metals by a complex treatment of the flotation products from South African platinumcontaining chrome ores. The procedure involves: autoclave leaching, roasting, hydrochlorination and precious metal recovery by sorption. Autoclave oxidative leaching of the initial material allows the nonferrous ...
Separation occurs in flotation cells where the reagents (chemicals) are added to aerate slugs carrying highgrade collected PGM (Anglo Platinum Limited, 2009). An approximate composition of a metric ton received at the ore concentration unit of Waterval is The converter matte analysis in Table 3 shows the increase of concentration in base . Get ...
1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Twostage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter or blister) copper 3. Refining the crude copper, usually in two steps
The flotation columns are used for finer minerals and they ... ( return of converter slag to the furnace). Sanitary sewage effluents require treatment in a separate facility or discharged to a municipal sewer. Get Price PLATIRUS PGM Recycling. The separation of pgm microparticles from the molten slag phase is impacted by the slag viscosity ...

platinumgroup metals (PGM) and gold from Stillwater Complex flotation concentrate. The Stillwater Complex is the only major PGM re source. Development of a suitable extraction technique will contribute to its exploitation. The concentrate was roasted at 1,050° C to convert
After flotation and concentrate drying, ... The matte is further treated in converting steps. PGM smelting can be compared to the smelting of nickel matte by SAF, with SMS Demag's rectangular furnace being the ideal equipment for this technology . ... PGM slag FeCr slag FeMn slag FeNi slag
· 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.
The Naoshima Smelter has employed the convert er slag flotation method in order to increase reverberatory smelting capacity instead of returning slag to the reverberatory furnace. As the result, we could point out the following advantages; 1) Copper anode produced from copper concentrate was increased 25%, from 3,000T/M to 3,800T/M.
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
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 ...
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 .
· There is general consensus on the priority to develop saleable products derived from waste especially CO2 utilisation and specific mineralisation. The environmental CO2MIN Project aimed at minimising the CO2 emitted by the German cement industry by capturing of CO2 by using mineral resources (olivine) and waste materials (steel slag) is one of the important developments.
Namibia Custom Smelters (NCS) process a range of copper concentrates in their three furnaces, namely; top submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags. The copper content of the slags range between to 5 wt. % and this is considered .

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.

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.
