Large amounts of slag are generated during pyrometallurgical processing in copper production. Due to the presence of valuable elements, the improper disposal of huge quantities of copper slag produced, results in significant loss of resources as well as environmental issues. Analyses of the copper slag show that it contains valuable metals, …
Slag is further cleaned in a slag cleaning furnace or directed to slag flotation. The SO 2 gas generated during the smelting stage is led to an acid plant to produce sulfuric acid ... The BBR-BCC process was an exception, because otherwise the discharge slag copper would have been too high with these parameters. Thus, the recovery was increased ...

Keywords: Pyrometallurgy, furnace, auxiliary equipment, copper slag launders Abstract – Pyromet has designed copper launders for tapping slag. What makes Pyromet's launder design innovative and safe is that it does not have any cooling water channels underneath the launder runner, whilst achieving effective cooling ...
Fayalite is the main phase of copper slag and a type of Fe silicate glass that is composed of a polymerized network of silicate tetrahedrons, in which SiO 2 and FeO are generally considered as network formers and modifiers, respectively. The structure of fayalite is shown in Fig. 13 [107].In iron silicate glass, O 2− exists in the form of bridging and non-bridging oxygens (BOs and …
Two slags from steel production in the electric arc furnace (Alcalá de Guadaira, Sevilla, Spain) were used: electric arc furnace slag (EAFS) (3–5 mm particle size) originated in the primary metallurgy or fusion and ladle furnace slag (LFS) (0–2 mm particle size) originated in the secondary metallurgy or refining of the molten bath produced ...
During copper matte smelting, a lag exists in the analysis of the smelting results, leading to the production parameters not being effectively adjusted in time. As the first smelting process in copper pyrometallurgy, the optimization of the amount of raw material, as well as the prediction and adjustment of slag and matte phases, has become an extremely important …
Commonly used alkali activation precursors such as blast furnace slag and fly ash will soon become less available due to resource competition, and may cease to be produced in certain regions. This limitation in future supply is a main driving force for the investigation of alternative precursor sources, such as non-blast furnace slags and non-ferrous slags, to …

Copper is present in a smelting slag from Teniente Converter (TC) in the form of mecha-nically entrained matte inclusions and dissolved copper. Copper recovery from the slag requires …
The slag contains 0.5–1% Cu and it is almost always treated for copper recovery either by electric furnace settling or by flotation of the copper from finely ground solidified slag. Off-gas, rich in SO 2, is collected continuously, cleaned, and sent to a sulfur fixation plant.
The mixture of matte and slag formed in the S furnace flows continuously to the CL furnace, where the denser copper matte separates from the discard slag. The matte is then siphoned to the C furnace, to be continuously converted to blister copper and C-slag. The latter is water granulated, dried, and recycled to the S furnace, while blister ...
Reactivity is the key to the successful utilization of waste materials. Ferronickel slag, copper slag, and copper tailing show a high amount of SiO 2 that forms a secondary calcium silicate hydrate if mixed with cement through a pozzolanic reaction. Steel slag has CaO as the most dominant chemical component and is close to Portland cement.
In the present work, the effects of amount of coke, reduction temperature and furnace types on copper slag smelting in a dc arc furnace were studied. Optimum coke amount was found to be 10% of the slag weight in an open-top furnace for a 1 hour reduction time in the...
AlucoFlux DO – Deoxidizing flux that is used for copper-nickel, aluminum-bronze, manganese-bronze and pure coppers. When used prior to pouring, eliminates the need for inert (nitrogen) degassing. ... The addition of Slag-Grip to the ladle or furnace will assist in removing the slag. Not for use in electric glow-bar furnaces. AlucoFlux FW-11 ...
Copper oxide reduction accomplished with injection of reducing media for several tuyere/plug arrangements in a slag refining furnace was simulated and the reduction performance was compared.
Copper slag cleaning using the flotation method and/or in an electric furnace is widely adopted in industrial production.[2,3,4,5] The flotation method has the advantages of low energy consumption and low copper content in the slag, but the waste liquid treatment after flotation has always been an issue.
At the time of the fire, the town of Onota had a population of around 500 people and most of these worked in some manner for the furnace operations. At one time there were 29 blast furnaces in Michigan's Upper Peninsula. All of these furnaces are now gone with the exception of the Bay Furnace Ruins and one still standing at the Fayette State ...
