Carbothermal reduction of copper smelter slag for
Jun 01, 2017 Copper smelter slag typically contains about 1 copper and 40 iron depending upon the initial ore quality and the furnace type. Significant amounts of silica and minor amounts of other elements e.g., zinc, molybdenum, lead and arsenic are also associated with this slag.

balance of the production plant 6, 7. In this way, iron contained into slag, using an adequate treatment to separate it, could be used for the iron industry and steel fabrication. Silica could be used for ceramics and glass wool fabrication. Both materials constitute more than 50 of this phase, so the impact in
Extraction of iron from copperplant slag SpringerLink
Jan 05, 2017 In the production of copper from sulfide ore, slag accumulates at the processing plant. In the present work, the phase transformations that occur in such slag during its reduction by the gasification products of carbon at 1100 and 1200 C are investigated. Experiments show that most of the iron present in such slag may be converted to metallic form by the gasification products of carbon in cupola

Desulphurisation Slag is an iron slag derived from the desulphurisation skimming process. This material is an iron by- product that is encapsulated in varying levels of contaminants S,Mg,Si, but has a stable chemistry with 75 -80 chemistry. The level of Fe in the slag has been estimated by water displacement test.
What Is Copper Smelting with pictures
Feb 23, 2021 A pot made out of copper. Matte is then poured into a converter where it reacts with air, lime, and silica to separate the copper from iron slag. The resulting copper from this step is known as blister copper. Blister copper undergoes further firing and
123 Primary Copper Smelting
reverberatory or electric furnaces. 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 copper oxide is converted to copper sulfide. The copper sulfide is removed and the remaining slag is
Sustainability of Concrete Using Copper Slag as
Copper Slag Copper slag produced during the matte smelting and refining of copper ore, during which, the iron present in the copper concentrate combines chemically at 1200 C with silica present in flux materials such as river sandsilica sand quartz fines to form iron silicate, which is termed as copper slag.

Recovery of iron from copper flash smelting slags Mineral
Copper slag contains iron in the range of 4245, which can be recovered and recycled along with the contained copper to obtain an ironcopper alloy and a final slag rich in oxides. Therefore, the present work shows the experimental results of the reduction of a flash smelting slag using coke as reductant up to 150 of the stoichiometric ...
RECOVERY OF IRON FROM COPPER FLASH SMELTING
copper must be also as a separate phase due to the limited mutual solubility between iron and copper under these conditions. Thus, this iron alloy requires a further treatment for decreasing copper to a lower content in the final metal phase. However, the copper content in the final slag decreases to a minimum value of 0.06
