In the process for the removal of inorganic dusts, ash, dirt, slag and other impurities deposited on the walls and uptakes of reverberating smelters used to recover copper from ores, by contacting said impurities with fluxing agents at the operating temperatures of said smelters and equipment, the improvement comprising the use of a fluxing agent consisting essentially of 10 to 100% alkali metal

Critical review of applications of iron and steel slags

2019-1-8  Electric arc furnace slag Steel slag is obtained from steel-making process within an EAF where an electric arc is used for charging the steel scrap, molten iron and fluxing agent rather than the gaseous fuel (Yildirim and Prezzi 2011). Also, the amount of steel scrap could be more than that of pig iron, essentially making the EAF process a steel scrap recycling process.

Blast Furnace an overview ScienceDirect Topics

Integrated coal-fueled steel mills accounted for ∼60% of the 1.4 Gt of global steel produced in 2008, consuming 15–18 GJ per t-steel produced and emitting a global average of ∼1.4 t-CO 2 per t-steel produced. In the first stage of the steelmaking process, high-grade coal (anthracite) is used to fuel a blast furnace in which iron is extracted by reduction from the ore hematite (Fe 2 O 3
