Gangue Mineral - an overview ScienceDirect Topics

If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite,

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.
