Amphiphilic collector , an isopolar organic compound having both anions and cations in the molecule. The common anionic groups are mainly -COOH-SO 3 H groups and -OCSSH groups; the cationic groups are mainly -NH 2 . Cationic agents containing anionic and cationic groups, various amine acids, amine sulfonic acids, and amine alcohol xanthate and diethylamine xanthate for flotation nickel or secondary uranium ore have been studied. Wait. The structural formula of diethylamine ethyl ketone is as follows:
(C 2 H 5 ) 2 NCH 2 CH 2 OCSSNa
Its dissociation in aqueous solution is related to the pH of the medium:
In an acidic medium, diethylamine xanthate is cationic
(C 2 H 5 ) 2 N + HCH 2 CH 2 OCSSH
In an alkaline medium, diethylamine xanthate is an anion
(C 2 H 5 ) 2 NCH 2 CH 2 OCSS - +Na +
At the isoelectric point, it does not dissociate, but is a neutral molecule.
(C 2 H 5 )2NCH 2 CH 2 OCSSH
Therefore, it is possible to adjust the pH of the slurry to produce different collection effects.
