Claims16
A froth flotation process for recovering a metal mineral from a metal mineral containing ore, which process includes mixing with a flotation feed comprising a ground pulp of the ore and water a collector for said metal mineral, said collector comprising a first reagent comprising at least one member selected from the group consisting of unsubstituted primary amines of formula R--NH.sub.2 and unsubstituted secondary amines of formula R.sub.1 R.sub.2 --NH where each of R, R.sub.1 and R.sub.2 is an aliphatic hydrocarbyl group having from 8 to 22 carbon atoms and the salts of said primary and secondary amines;
- and said collector further comprising a second reagent comprising at least one member selected from the group consisting of xanthates, dithiophosphates, mercaptobenzothiazoles, xanthogen formates and thionocarbamates to form a mixture;
- subjecting the mixture to flotation;
- and recovering the metal mineral in a flotation froth.
