Research has shown that milled anthracite can be used for this process, with the ability to reduce and thus remove zinc oxides in efficiencies exceeding 80%(14). Black Oxide African Pegmatite's carbon based black oxide is used to incorporate pigment into ceramic glazes, polishing compounds, filler, construction material and even inks.
Electric arc furnace steelmaking (EAF) process is one of the ways to produce steel (Yang et al., 2021). Compared with the EC of 600–700 kgce and GHG emissions of 2000–2400 kg per ton of steel in BF-BOF route, the EC and GHG emissions are only 350 kgce/t and 500–700 kg/t in EAF route ( Shangguan et al., 2021 ).
The fly ash briquetting process. Process for separating anthracite coal from impurities. A process for treatment of anthracite coal when combined with cinders and/or klinker type ash produced by old cleaning plant boilers comprising sizing of the mixture and magnetic separation of the ash from the mixture thereby improving the combustion value.
Conventional (anthracite, calcined petroleum coke, and coke) and non-conventional (biochar, and biocokes (3 wt.% torrefied wood, and 3 wt.% petroleum coke + 3 wt.% charcoal)) carbon-bearing sources have been studied for their use in electric arc furnace (EAF)-based steel production. Commonly, for the use of carbon sources in …
The fast heating of anthracite coal and, consequently, the greater release of volatiles may also cause carbon network (or C-structure) fragmentation, resulting in a major increase in the FeO-C reaction rate and the height, as shown in Fig. 11. The same behavior was not observed when anthracite char was added to the same slags.
Metallurgical coke is an important raw material for pig iron production in the blast furnace. During this process the coke undergoes severe mechanical, thermal and chemical stresses. One of these is the CO2 -gasification which may lead to a decisive mechanical weakening of the lump coke by increased carbon burn-off.
Anthracite coal typically has moisture content of 3 % to 8 %, ash content of 11 % to 18%, and sulphur (S) content of 0.4 % to 0.7 %. The high variation in ash content translates into wide variations in fixed C content and hence, for use in EAF the ash content is to be kept to a minimum. The ash consists primarily of silica (SiO2).
The anthracite contained 7.73% volatiles, and it contained more fixed carbon and had a lower ash content than the coke breeze. It can be seen that the contents of N and S in anthracite are ...

The ash of Anthracite was notably more acidic than the biomass-based carbon materials, due to a high concentration of SiO 2. Since SiO 2 lowers the melting point of compound oxides, Anthracite's ash completely melted at 1600 °C. The unmolten fractions of the ashes of the other carbon materials at 1600 °C consisted of CaO- and …

1 Acid Bessemer Process. Major advance in steelmaking occurred in 1855, when Henry Bessemer took out his first patent for the production of malleable iron and steel without using fuel. Bessemer proposed a production method of steelmaking within a very short time (15–20 min) by blowing air through molten pig iron.
The high-intensity smelting (HIsmelt) process has its origins in the early 1980s when Rio Tinto Limited identified the potential to adapt the high scrap rate steelmaking and iron bath coal gasification processes developed by Klockner Werke to the direct smelting of iron ore.
