matter content in the gas off-take of a furnace varies with the design and dimensions of the furnace, electrode arrangement, material feed details, and operational conditions. In closed AC and DC furnaces wet scrubber systems are mostly used to cool and clean the gas extracted from the furnace. Currently some of the CO-rich off-
Slag cleaning at copper and nickel smelters is typically done using an electric furnace process. The design of Outotec slag cleaning furnaces is based on our extensive …
ACP slag is fed to the slag-cleaning furnace along with a reductant and a sulphur source. Slag-cleaning-furnace matte is granulated for processing by the ACP, while slag is granulated and processed in the slag mill. The slag mill and flotation circuit treats granulated slag from the electric furnaces and slag-cleaning furnace to recover ...
An uniquely-designed flash furnace for smelting of nickel concentrate and for the recovering of metal values from the slag generated has been in successful use for nearly six years. Within the last eighteen months the ability of the furnace to treat slag arising from converting operations without significant reduction in capacity has also been successfully demonstrated. Previously, …
With the Outotec Electric Slag Cleaning Furnace, the cleaning of smelting furnace slag is carried out using surface coke reduction in an electric furnace.
Key to implementing modifications aimed at improving the copper slag reduction process is a thorough understanding of its kinetics and thermodynamics. Electric resistance furnaces are …
Slag from the reactor and the converters is sent to the concentrator to recover the copper. This concentrate is fed back into the reactor, and the slag tails go to the tailings pond. The acid plant production is currently 525,000 …
The FeNi furnace is used in smelting plant for smelting laterite nickel ore to produce nickel pig iron. The most advanced RKEF processing technology is adopted with rotary kiln and electric furnace. DHHI is capable of contracting …
Copper slag cleaning in an electric furnace is a critical process for reducing the excessive magnetite (Fe3O4) present in the copper slag to decrease the slag viscosity, which can promote the ...
Based on the assumptio n of 95% availability each of the calcinatio n plant and the smelter unit, the resulting overall plant availability is approx. 90 %, i.e. approx. 7,900 hours per year [11,12]. For large scale FeNi plants based on 2 rectangular smelters SMS DEMAG recommends a "two-in-line-so-lution", as shown in figure 2.
A general flow sheet incorporating an Ausmelt furnace to smelt and convert nickel sulphide concentrate is shown in Figure 3. Figure 3-Outotec Ausmelt Process for nickel/PGM smelting During smelting, nickel sulphide concentrates are fed into the Ausmelt Smelting furnace along with
Copper slag cleaning in (electric) furnaces has become increasingly popular over the recent decades. METIX, part of the SMS group, has recently constructed an electric furnace for the First quantum project at …

The copper slag cleaning in an electric furnace is based on slag reduction and settling of copper matte inclusions. Copper recovery depends on the slag temperature, degree of magnetite reduction and slag residence time. The formation of solid buildup on the furnace hearth leads to the decrease of furnace volume and slag residence time, affecting
