Currently, three Vaniukov Furnaces are operating at Norilsk Nickel's plants. Two Furnaces are installed at the Norilsk Combine's Copper Plant and are used for copper ore concentrates processing to ~60% Cu grade matte. The third Furnace is operating at the Norilsk Combine's Nadezhda Metallurgical Plant; it processes copper concentrate from …
The first is pyrometallurgical reduction and settling, performed in an electric or fuel-fired slag-cleaning furnace. The second is minerals processing of slow-cooled slag, including …
The use of an electric arc furnace for recovery of metal values from slag generated in a secondary copper smelter has been successfully demonstrated and …
The use of an electric arc furnace for recovery of metal values from slag generated in a secondary copper smelter has been successfully demonstrated and commercialized.
Typically, vanadium is recovered as a by-product from the ironmaking process, while the diluted titania slag is stockpiled. Fluxless smelting in a direct-current open-arc furnace is proposed as an ...
During the last few decades, the pyrometallurgical processes used for cleaning copper smelting slags have been steadily optimized. The electric furnace or rotary slag-cleaning furnace are now generally used to perform this task, giving a level of copper in discard slag typically in the range of 0.55 wt.% and 1.3 wt.%, with most …
tity of iron as oxide in the slag. Ni-Cu SLAG CLEANING Many nickel-copper smelters employ a slag-cleaning process whereby the con-centrates are fed to a furnace that pro-duces a matte (for further treatment) and a slag (which is stockpiled). The furnace matte is treated in a converter (often a Peirce-Smith) to remove most of the remaining iron ...

In view of the non-renewable reductant resources and carbon neutralization in the process of copper slag cleaning in an electric furnace, this study proposed to use …
The new primary smelting technology employs a Double Sided Blown (DSB) electric furnace fitted with 3 electrodes . Refractory lined furnace walls are cooled by copper water jackets. The DSB feeds material comprising of sulphide copper concentrate, coal …
The traditional route of copper making from chalcopyrite ore/concentrate involves a number of pyrometallurgical processing steps, such as roasting, smelting, converting, and refining, which makes ...
In view of the non-renewable reductant resources and carbon neutralization in the process of copper slag cleaning in an electric furnace, this study proposed to use waste cooking oil as reductant to replace fossil energy. Combined with the phase equilibrium theory and experimental results, the harm of excessive magnetite in the copper smelting slag to …
The performance of pyrometallurgical slag cleaning furnaces at many primary copper smelters is dependent in part on the quality of the converter slag, commonly produced in the batch-wise Peirce Smith … Expand
The ore used in Euro- nickel Industries on average contains 1.8% Ni. And another ... Historically, the smelter used ore only from the R'zhanovo Mine. Later however, it started ... tons of slag are removed from the electric furnaces, daily. When the ore is in lava state,
The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and cobalt from copper slag was investigated through the process of sulfation roasting–water leaching and the process of sulfation …
Slag cleaning furnaces are commonly connected to smelting units such as Teniente and Noranda converter, Outokumpu flash smelter, reverbertory furnaces. ... of laterite-nickel ore was imperative ...
With 's Outotec Electric Slag Cleaning Furnace, the cleaning of smelting furnace slag is carried out using surface coke reduction in an electric furnace. The circular or rectangular electric furnace is operated in batches and equipped with three or more Söderberg electrodes.
The performance of pyrometallurgical slag cleaning furnaces at many primary copper smelters is dependent in part on the quality of the converter slag, commonly produced in the batch-wise Peirce Smith converter (PSC). In order to understand the impact of converter slag chemistry and at the same time help optimize the converter …

The characterization of two wastes, SWD and CFD, generated in the reprocessed of slag cleaning furnace flue dust from copper smelting have been performed as an essential step towards finding applications or treatments for these wastes. Both waste contain very fine particles size and are mainly enriched of Zn, Pb and Fe.
Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as
