Recycling of ladle furnace slags Abstract Ferrous industry slag is waste product of all steelmaking manufactures. These materials should be reused or stocked. There is abundant literature on the subject of reuse and recycling of blast furnace(BF), basic oxygen furnace(BOF), electric arc furnace(EAF).
Electric Arc Furnace Slag (EAF or steel furnace slag) Produced when scrap metal and fluxes are oxidized by the use of an electric current. Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include
We sought to develop an optimized particle sizedependent separation method to lower the Fe content of pulverized glassceramic electric arc furnace (EAF) slag for its improved reclamation as construction materials by considering the structures and the mechanical behavior of the discrete solid phases.
Nov 15, 2016· Abstract. We sought to develop an optimized particle sizedependent separation method to lower the Fe content of pulverized glassceramic electric arc furnace (EAF) slag for its improved reclamation as construction materials by considering the structures and the mechanical behavior of the discrete solid phases.
Electric Arc Furnace (EAF) slag from one of the steel plants in Western India has been characterised in detail. Its effectiveness as hydraulic material is examined before and after heat treatment in an induction furnace. The study shows that while there is a marginal reduction in the early age strength of the Portland Slag Cement mortar, the ...
The electric arc furnace is tapped several times per day followed by a gravity separation process to separate the metal phase from the slag. The recovered metal is returned to the customers as large slabs or it is sold on the free market. The slag is used in road constructions or as a .
Gravity, size, and magnetic separation techniques could be designed into flow sheets for recovering the iron units. The resulting fine scrap concentrate could then be pelletized and recycled into the blast furnace [26, 27]. Steelmaking slag samples used in this study were provided from an integrated iron

Phosphorus Slag. Phosphorus slag is a byproduct of the elemental phosphorus refining process. The elemental phosphorus is separated from the phosphatebearing rock in an electric arc furnace, with silica and carbon added as flux materials to remove impurities during the slagging process.
Method and apparatus for separating iron or steel from slag by inductively pumping the iron or steel up an inclined trough away from the nonpumped slag. USA Apparatus for separating slag from a molten metal Google Patents Apparatus for separating slag from a molten metal Download PDF Info Publication number ...
Electric arc furnace slag is a byproduct of the production of steel in an electric arc furnace. In electric arc furnaces the charge materials (scrap iron and steel) are loaded into the furnace and directly exposed to electric terminals. The current passing through the terminals creates an electric arc that melts the charge materials.
quantity of slag produced per year, the recovery of nickel from the EAF slag will add benefits to the entire process. The target of the current work is to investigate the possibility of nickel recovery from EAF slag by magnetic separation.
The ferroalloy separation from the lumpy slag happens in a special process, which is based on a gravity and magnetic separation. The first stage of slag processing is crushing and sc reening the feed material to fractions of 04 and 422 mm. Coarser fractio ns are handled by a heavy media separation the DWPmethod. A magnet
• The bulk density of asphalt mixes with EAF slag aggregates is 1520% higher than conventional mixtures, on account of the high specific gravity of the slag. • Slag mixtures usually show higher void contents, because of their the high angularity of their particles, which generates higher voids in the mineral aggregate.
Aug 15, 2015· EAF slag shows some chemical changes and slight expansiveness over time. • Collaboration producersconsumers of EAF slag is essential to efficient reuse. • EAF slag is a suitable aggregate for hydraulic cement concrete. • EAF slag forms a particular type of microstructure in the interfacial transition zone.
Separating titanium from slag by gravity separation or flotation process. High titanium slag is formed after the physical production process of titanium ore enrichment material, through the electric heating and melting of titanium, the enrichment of titanium in the titanium dioxide and iron melting separation obtained TiO2 content high concentration. . High titanium slag is not waste residue ...
The iron/steel slag processing flow is schematically shown in Fig. 2. Steelmaking slag is subjected to the following four processes: ① solidify and cooling of the hot molten slag, ② crushing and magnetic separation treatment of the slag to recover the metal iron, ③ crushing and classification of the slag for grain size adjustment
Metal Recovery from Steelmaking Slag Qi Yu Master of Applied Science Materials Science and Engineering University of Toronto 2018 Abstract An experimental study was carried out to recover metal values from a steelmaking slag through air oxidation and magnetic separation. The oxidation of slag was carried out in both solid and
