ABSTRACT:
A process for the separation of scheelite from calcite present in an ore or a concentrate formed from an ore, which process includes the steps of decomposing any flotation agent residues contained in the concentrate, and treating the ore or concentrate to condition the particle surfaces with a mono-substituted butane diamine of the formula H.sub.2 N.C.sub.4 H.sub.8.N(H)R, wherein R is a long-chain saturated or partially-unsaturated aliphatic hydrocarbon radical having at least 14 carbon atoms. The treated ore or concentrate is subjected to flotation in an aqueous system, and the scheelite is recovered in the flotation froth.
