The following structures are reported in literature: (1) C6H13S(CH2)2 NH2 (2) C6H13S CH2 N C C2H5 2 ϭ Dow Chemical designation F1 H O (3) ϭ Dow Chemical designation F2 C6H13CH CH2 ϭ Dow Chemical designation S1 S (4) C6H13SCH3 ϭ Dow Chemical designation S2 (5) CH3CH2S(CH2)7CH3 Ethyl-n-octyl sulfide ϭ Dow Chemical designation S7 The new collectors are much weaker than either dithiocarbamates or dithiophosphates. It was reported, however, that they are more selective than are other conventional collectors.
Hydrofluorosilic acid is a strong depressant for many silicates during flotation of a number of oxidic minerals. It is used for gangue depression during flotation of tin, columbite and tantalite.
