Hence reverse flotation can be employed rather than direct flotation wherein major proportion of the material,otherwise, would have to be floated. As such,the reverse flotation is the usual process for the beneficiation of iron ore slimes. Amines are the only cationic collectors used by industries in reverse flotation of iron ores.Accounted for a increase in the content of iron and a con- siderable reduction in the SiO2 content in the iron con- centrate, while the recovery of the mass and of Fe fell. It is important to add a depressant agent to the iron mi- nerals in the iron ore reverse flotation. In this work, corn starch and CMC (carboxymethylcellulose) were used.Shandong 1500t d Iron Ore Processing Project. Xinhai increased anionic reverse flotation process of magnetic concentrate on the basis of the single magnetic separation process. Iron ore concentrate was obtained directly with a roughing, tailings were discarded with three scavenging, middlings returned to efficient thickener.

The flotation of iron ores is usually performed by reverse flotation using cationic or anionic collectors [17]. The reverse flotation using cationic collectors is the most popular flotation route for the upgradation of low-grade iron ores and iron ore tailings [18, 19]. In the reverse cationic flotation route, after depression of iron.Flotation of iron ore The main objective of iron ore flotation is to upgrade the concentrate by removing silicates and or phosphorus-containing minerals. The use of silica flotation has increased in recent decades. The trend will continue as complex ores have to be mined and higher-grade iron ore concentrates with fewer.
