- 1 - ABSTRACT OF THE DISCLOSURE Direct flotation of pyrochlore from its ore can be carried out at acidic pH using 1-amidoethyl-2-substituted imidazolines of the formula (I) Image wherein R and R' are independently alkyl or alkenyl of 8 to 22 carbons, or their salts. In the presence of large amounts of carbonate in the ore, the pulp is acidified with hydrofluoric acid, fluosilicic acid, or their acid reacting compounds. Using this process, pyrochlore concentrates can be obtained by direct flotation from ore containing 0.1% or more of sulphide compounds calculated as FeS2.
