Electric arc furnace carbon steel slag (EAF)

Production and Processing. An Electric arc furnace (EAF) produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current Lime added (as flux) combine with silicates and oxides to form liquid slag. EAF slag has a lower density than steel and therefore floats on top of the molten steel.

Manganese processing | Britannica

It can be produced by two methods. In the first, ores are selected on the basis of their acidity so that, on smelting, 70 to 80 percent of the manganese is recovered in the melt while a slag containing 30 to 42 percent manganese is also obtained. (This slag can be resmelted to produce silicomanganese; see below.)

Dry Granulation of Blast Furnace Slag - Steel360 News

Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag. Heat is recovered from the slag in the following ways. As the spray of slag particles moves outwards from the atomizer, heat is lost by radiation to the vessel and by convection to the air moving through ...

Tin processing - Mining and concentrating | Britannica

In a typical reverberatory process (the most commonly used), the furnace is heated to 1,300-1,400 °C (2,375-2,550 °F) for a period of some 15 hours, during which it is stirred frequently, especially during the later stages. This process produces a pool of molten tin, on top of which floats a slag containing most of the unwanted impurities.
