RECOVERY OF PIG IRON FROM COPPER SMELTING SLAG BY ...

Copper slag is a by-product obtained during smelting and refining of copper. Copper smelting slag typically contains about 1 wt.% copper and 40 wt.% iron depending upon the initial ore quality and the furnace type. Main components of copper slag are iron oxide and silica. These exist in copper slag mainly in the form of fayalite (2FeO SiO2).

Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state.

Copper Slag - an overview ScienceDirect Topics

The density of copper slag varies between 3.16 and 3.87 g/cm 3 based on the amount of iron content. The average specific gravity of copper slag is about 3.5 g/cm 3, which means copper slag is denser than ordinary natural aggregates. In general, water absorption of copper slag is very low.

Iron ore was first discovered in the U.P. in the 1840s. Although the iron ore rock was up to 72 percent pure, it was necessary to remove the impurities and extract the iron. Iron is purified from iron ore in a huge container called a blast furnace. Beginning in the 1840s in Michigan's Upper Peninsula, iron ores such as hematite and magnetite ...

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
