Titanium (Ti) is abundant in the earth’s crust (0.7 mass pct as oxides).[] Metallic titanium shows excellent properties, such as the highest specific strength among structural metals [203–224 kN m kg −1 for Ti-6 mass pct Al-4 mass pct V (Ti 6–4)[]] and high corrosion resistance even in aqueous solutions containing chlorine ions.[]Compounds. Of the wide variety of compounds formed by manganese, the most stable occur in oxidation states +2, +6, and +7. These are exemplified, respectively, by the manganous salts (with manganese as the Mn 2+ ion), the manganates (MnO 4 2−), and the permanganates (MnO 4 −).As in the case of titanium, vanadium, and chromium, Manganese Uses, Facts, & Compounds Britannica

Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates. Non Manganese +3 is highly reactive and can break down the chemical bonds of lignin, making it available as food for the fungus.
