ABSTRACT:
Mono- and dithioic esters, the alcohol residue of which carries a group including one or more oxygen atoms, are prepared by the action of an oxygen-containing organic compound, carrying an active atom, upon a mixed magnesium salt of a mono- or dithioic acid, ##STR1## where Y is O or S, R is a hydrocarbon group and X is a halogen. The product obtained is treated with an aqueous acid. The new products so synthesized are of the type ##STR2## notably those where R' is a chain, --(CH.sub.2).sub.n --, with n=1 to 12, Z being --OH or --COOH and are used as a collector in the flotation of minerals.
