ION FLOTATION WITH ANIONIC REAGENTS

摘要

Compounds of general formula (I), wherein Y<+> is a metal cation or a hydrogen ion, and either R<1> is an isothiouronium or amine group, m is 10 to 18, n is 0, and R<2> is H, or R<1> is H, m is 10 to 18, n is 1 to 4, and R<2> is an isothiouronium or amine group. Methods for preparing the compounds of formula (I). Methods for ion flotation, especially of gold, using compounds of formula (I) as ion flotation reagents.
