Witryna1 lip 1997 · 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 … WitrynaSilicon, also silicon, is a chemical element with the symbol Si and the atomic number 14. It's in the 4. Main group (carbon group), or the 14. IUPAC Group, and the 3.
