A process for the selective flotation of metal ores is described, wherein ionic organic collectors are utilized, which have the formula:
where R and R₁, like or different from each other, represents:
H, a halogen, a straight or branched C₁₋₉ alkyl group, an alkoxyl or hydroxyalkyl group in which the alkyl moiety contains from 1 to 9 carbon atoms, or a phenyl group;
and M represents; H, Na, K, Li, Cs, NH₄.
描述了一种选择性浮选金属矿石的工艺,其中使用了离子有机捕收剂,其化学式为
其中 R 和 R₁,彼此相同或不同,代表: H、卤素、直链或支链 C₁₁:
H、卤素、直链或支链 C₁₋₉烷基、烷氧基或羟烷基(其中烷基含有 1 至 9 个碳原子)或苯基;
M 代表 H、Na、K、Li、Cs、NH₄。
