Comparative studies of reverse cationic/anionic flotation of Vale iron ore
Flotation tests were conducted in a 3L laboratory Denver cell using 2.5 kg iron ore. For both conditioning and flotation, the impeller speed was 1200 rpm. Before flotation, the pulps were first conditioned with starch for 3 min and then conditioned with a collector for 3 min. The reverse cationic flotation tests were conducted at pH 10.5 and ...

Flotation | Mineral Processing, Separation & Beneficiation
William Andrew Hustrulid. Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to.
