FLOTATION ADJUVANT AND METHOD FOR THE FLOTATION OF NON-SULPHIDIC ORES

摘要

Flotation aids and a process for the flotation of non-sulfidic minerals. The flotation aids have the formula 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.
