Promoter Reagent S- 6966 I is composed of sodium O,O-dipropylphosphorodithioate, a small amount of sodium hydroxide and water. Lastly Promoter Reagent S-6966 is composed of O,O-dipropylphosphorodithioate, sodium O,O-bis(2-methylpropyl)phosphorodithioate, sodium hydroxide and water. It is our unstanding that these products are used as sulfide mineral flotation collectors.
