Review on tannins: Extraction processes, applications and possibilities
For efficient extraction, these plant parts are grounded prior to any type of extraction (Antwi-Boasiako and Animapauh, 2012; de Hoyos-Martinez et al., 2019).However, the particle size varies depending on other parameters like efficacy level, time, temperature, solvent type, raw materials type, and process.

Ironmaking 101 – From Ore to Iron with Blast Furnaces
Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard coal ...
