The European steel industry produces about 70 million tons/year of steel by the electric arc furnace (EAF). The slag consists of about 15% by weight of the produced steel, thus from the perspective of the circular economy, it has a high potential as a coproduct. This research aims to assess an innovative reuse of EAF slag as filler in different polymer matrixes: thermoplastic (polypropylene ...

The steel is refined by oxygen insufflation, and the lime is used to form a slag to capture impurities contained in scrap, which form oxides under the action of oxygen, and bind to lime. The coal injection makes this slag ing, which protects the upper vat from the radiation of the electric arc and improves the energy transfer to the steel bath.

Blast furnace slag. Blast furnace slag (BFS) is a byproduct from iron production in blast furnaces, which are fed by a mixture of ironore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...

Mill scale is a mixture of iron oxides and other impurities formed in high temperatures. Rust is also a mixture of iron oxides but is created in the presence of moisture in everyday temperatures. For the same thickness, rust is far easier to remove than fresh scale. If scale is old, dry, and rusty, it is almost as easy to remove.
