Equipment Used For Firing/Smelting Ore Furnace Or Oven For Firing/Smelting: It must heat to 1950 degrees F for gold and 2100 degrees F for silver. A muffle furnace is best. It fires to about 2300 degrees F and the ingredients can be easily added to the ore while firing. Crucible: Clay or graphite crucible to use in a muffle furnace. Other types of crucible can be used in an electric furnace.

Steel plant slag is a solid industrial waste generated from steel industries in production of steel and mainly these waste includes blast furnace and steel melting slag (open hearth or LD process slag). It can be categorized as carbon steel slag and stainless steel slag according to the type of steel, and as pretreatment slag, LinzDonawitz (LD)

Cement. Production of granulated blast furnace slag is used to make Ecocem, a superior slag cement ideal for underwater applications.. Slag Cement Slag is a byproduct of iron and steel making. In nature, the ores of metals are found in impure states, often oxidized and mixed in with silicates or other metals.

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being ...

Steel slag is a secondary resource of raw material in metallurgical plant. It can be directly taken back to sintering, ironmaking and steelmaking, and used as flux, from which the useful elements can be recovered7. It is advantage that the premelted flux is more easily remelted than the raw flux. On the other hand, steel slag can be used as construction

metal becomes steel. This sulfur removing reaction is: FeS + CaO + C = CaS + FeO + CO The CaS becomes part of the slag. The slag is also formed from any remaining Silica (SiO 2), Alumina (Al 2O 3), Magnesia (MgO) or Calcia (CaO) that entered with the iron ore, pellets, sinter or coke. The liquid slag then trickles through the coke bed to the
