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 ...
The process for laterites is very similar to that in copper smelting. Oxide-type nickel ores are charged ... nickel ore having nickel less than ... so a slag settling / cleaning furnace is needed ...
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. Blast furnace slag containing about 1.5% Cu, 1.0% Pb, 3.5% Zn, 1.0% Ni, 40% FeO and 1.0 opt Ag was retreated to recover better than 75% of the metal values. The addition of …
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 ...
Recovery of copper and cobalt from smelter slag using reductive-sulfurizing smelting method was performed in this study. The effects of reductive agent (coke), sulfurizing agent (pyrite), slag ...
This study aims at recovering valuable metals from nickel slag by employing pyrometallurgical techniques. A large amount of slag is generated during the nickel matte smelting. Nickel slag contains valuable elements such as copper, nickel, and cobalt, which can be recovered. Disposal of this slag results in loss of resources and may …

in copper, nickel, cobalt, lead, tin, zinc and precious metals (platinum/palladium) production10. Copper Slag cleaning furnaces are commonly connected to copper smelting units such as Teniente and Noranda converters and Outokumpu flash smelters. The main function of the furnace is the reduction of the copper level in the slag11.
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 …

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 …
mineral-ore flotation plant. The tailings ... 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 ...
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 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.
The smelting and converting El Teniente process for copper concentrates as well as slag cleaning furnace technologies to treat slags coming out from the El Teniente furnaces are widely applied ...
During the recovery of base metals from the Bushveld Igneous Complex ores, South Africa, a two-stage process is used to ensure complete recovery of nickel from the ore. A nickel flash smelting furnace is initially used to obtain the valuable metal but the loss of nickel in the slag amounts to about 4 % and thus an electric slag-cleaning …
chromium in converter slag render it unsuitable for recycling to the furnace and, to recover PGMs from chromium-rich converter slag, it must either be melted in a slag-cleaning furnace or treated in a minerals processing plant. Furthermore, high levels of chromium increase the liquidus temperature of the slag, resulting in excessive
