Natural ore flotation experiments
Butyl xanthate, Z-200 and DTPINa were used as copper sulfide collectors. Ammonium dibutyl dithiophosphate, Sodiumdiethyl dithiocarbamate and DTPINa were used as lead sulfide collectors, respectively, to contrast their flotation ability(Tables 5 and 6). When Butyl xanthate, Z-200, ammoniumdibutyl dithiophosphate and sodium diethyldithiocarbamate were used as collectors, MIBC was used as frother. The table indicated that DTPINa exhibited stronger foaming ability and preferable collecting efficiency without extra frother.
