Biotite chemistry
WebMicaceous minerals, known as layer silicates, are counted mostly as the gangue minerals associated with valuable minerals, especially iron oxides. They mainly reject through the reverse flotation process using the cationic collectors, e.g., ether amines, to improve process sustainability. Although ether amines have been applied for floating the wide range of … WebBiotite is a potential potassium mineral resource and the dissolution of biotite in H 2 SO 4 solution is a green chemistry approach for recovering potassium. To estimate the efficiency of leaching process and to understand the behavior of leaching reactors, the kinetics and mechanism of leaching potassium from biotite in H 2 SO 4 solution were studied in …
