· Many restrictions exist, however, on the utilization of steel slag. When steel slag is used internally, in steel plants, the most obvious problem is that of the enrichment of P and S (Drissen et al., 2009).The Bhilai Steel Plant in India was shut down because of its high S and P content (Das et al., 2007).The amounts of free lime and free MgO are important for the utilization of steel slag in ...

· You can pour slag into a mortar or pipe cap when it is hot from the furnace. When the metal has cooled, you can use the pestle for breaking out the button of metal. Angle Iron: To add necessary ingredients while the ore is in the furnace, a 3foot piece of 11/2 inch angle iron is handy.
Molten iron and slag collected in the crucible at the base of the stack, and the iron was run off at intervals. This was cast iron – an alloy of iron with carbon (3 or 4%) and other elements – sulphur, silicon and manganese. To produce wrought iron, the iron ingots, or pigs, needed further refining in the finery and chafery forges (see below).
· Raw materials. For the production of steel, there is a need for iron raw material in the form of iron ore or scrap metal, together with alloying elements so that the material acquires the desired for properties. In the production of orebased steel, coal is also needed as a reducing agent and limestone as a slag .
for recycling. Currently, at the Rönnskär smelter plant, copper slag is recycled in a continuous procedure, including fuming, settling, and granulation. The main product is called Iron Sand with smaller amounts of matte and speiss. These two phases contain a .

Substitutes: In the construction sector, ferrous slags compete with natural aggregates (crushed stone and sand and gravel) but are far less widely available than the natural materials.
In the iron and steelmaking process, over 600 kg of byproducts, such as steel slag, dust, sludge, and used refractory bricks are generated for each ton of crude steel produced. In fiscal 2018, Nippon Steel produced 41 million tons of crude steel and generated million tons of byproducts.

Slag is tapped intermittently into 15 ton slag pots and left to solidify and cool before crushing and milling. Iron is tapped intermittently into 35 ton ladles and then desulphurised and recarburised before being cast into saleable 7kg ingots drying ilmenite feedstock and crushed slag product.
An Integrated Compact Mill (ICM), based on a COREX C2000 plant and the Midrex DR plant was started up in mid 1999 at ArcelorMittal Steel South Africa (Saldanha Steel), situated near the west coast of South Africa. It is operated with mainly indigenous iron ores comprising SISHEN lump ore (80 ), CVRD pellets (0 20%) and indigenous coal from the VAN DIJKSDRIFT and GROOTELUK coal districts.
using crushing magnetic separation screening process to recover the metal iron contained in steel slag, and then smelting. For example, the amount of steel scrap in steel slag recovered by dielectric selfgrinding and magnetic separation in Anshan reaches %[6].
