Abstract

Novel thionocarbamate compounds having one or more substituents with five or more carbon atoms have been produced and evaluated as collectors used in froth flotation processes for the recovery of minerals. The amounts of minerals being recovered are greater as compared to the results obtained from using a conventional collector as a standard when using the novel thionocarbamates. Not only is the amount of materials recovered increased, i.e. enhanced yield, but also the novel thionocarbamate collectors have enhanced selectivity by rejecting iron to a greater extent than the standard so that the purity of the mineral being recovered is increased. A method of making the novel thionocarbamates is described using novel xanthates and amines, including novel amines. The advantage of the processes and methods is that the xanthates used to produce the novel thionocarbamates do not need to be pre-treated by being dried, purified, isolated, but rather the xanthates can be used in the form as produced.
