2020年7月30日 Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused on the reverse flotation of

2023年9月22日 Iron is considered the third most abundant mineral to be discovered, and it has different chemical forms. Iron oxides ore is the most abundantly available resource compared to sulfide and carbonate. 1 The majority of iron ore reserves in China are low-grade, finally disseminated, and scattered reserves. 2 The estimated national reserves are more than 20

2020年5月12日 Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation of iron ores,
