    Oct 01, 2010· 1. Introduction. The flotationof oxideminerals can be directly undertaken using anionic collectors, or indirectly, with amenableoxidesystems such as those ofcopperand lead, being sulfidised under controlled potential and then floated using xanthates (Lee et al., 2009).Alkyl hydroxamatesandalkylhydroxamic acids are used as direct collectors foroxideminerals, and have been mainly

    Isostearic acid, a liquid isomer of stearic acid, is used as an agent in a froth flotation process to concentrate the ironoxidein iron ores. By use of this flotation agent, the ironoxidein the ground ore is directly floated away from the remainder of the ore. The process enables a high amount of ironoxideto be concentrated from low grade ores
