Abstract (en)

[origin: US4457850A] Flotation aids and a process for the flotation of non-sulfidic minerals. The flotation aids have the formula <IMAGE> I wherein R repesents an aliphatic, cyclic, or alicyclic C7-C23 radical, optionally substituted with one or more hydroxyl, sulfhydryl, carbonyl, ether, or thioether groups; Xn+ is hydrogen or a water-solubilizing, salt-forming cation; and n is the valence of X. The invention also relates to ore suspensions and mineral concentrates in association with the above flotation aids.

Abstract (de)

Acyllactate der Formel I, <IMAGE> in der R einen aliphatischen, cyclischen oder alicyclischen Rest mit 7 bis 23 Kohlenstoffatomen und X<+> ein Wasserstoffion oder ein wasserlöslich machendes, salzbildendes Kation bedeuten, werden als Sammler bei der Flotation nichtsulfidischer Minerale verwendet.
