 A Canadian patent was issued on the froth flotation of barite or celestite
ores. The aqueous pulp of ore was treated with the required reagents, including
as an improved collector for the values, a fatty acid taurate amide of prescribed
formula or a 
mixture of fatty acid taurate amides. The values were selectively floated
in the froth."
