Extraction of Iron from Hematite - Xinhai

2020-4-21  Hematite reverse flotation method is a method used for the extraction of iron from hematite, which uses ionic or cationic collectors to float gangue minerals from raw ore. The anionic collector reverse flotation method is mostly used when the pH value is 8-9. It is used to treat quartz-containing gangue minerals.
