Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basicoxygenfurnace (BOF) steelmaking, electricarcfurnace (EAF) steelmaking, and ladlefurnace steel refining processes. The mineralogical and morphological properties of BOF and electricarcfurnaceladle [EAF(L)] slag ...

Recovery of metal from MSWI slag. Recovery of metals from MSWI residues closely depends on the characteristics of MSWI residues and the disposal strategy for MSWI residues. Since fly ash has high heavy metal and dioxin concentrations, it needs special treatments, such as vitrification by remelting and extraction using acid or other solvents.
An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking.

EAF DUST TREATMENT FOR HIGH METAL RECOVERY BY MICHIO NAKAYAMA * SYNOPSYS: Electric arc furnaces (EAF) generate much dust during operation, which contains very high percentages of zinc, lead, and ir on, as well as toxic organic substances. It is difficult to landfill it for environmental reasons, and not desirable in terms of wasting metal.
In metallurgical production, the traditional aim is to increase recovery of metal to the maximum. It becomes apparent that the application of the submerged arc furnace (SAF) in non ferrous metallurgy processes is increasing, in particular for the extraction of zinc, lea d, copper and nickel, but also for the processing of residues and stripping of
y slag practice is essential to use long arc practice and higher input into the EAF Coke breeze is injected at the slag/metal interface along with oxygen. Iron oxide of slag reacts with carbon, generates CO, causes ing. An arc length of 500 mm can be shielded with good y slag practice. y slag is good for ''P'' removal
