. i invention relates to the concentration of ores, minerals and the like, by differential flotation, and is more particularly adapted to substances or combinations have been used as flotation reagents and, in some of the ma combinations used, a soluUle sulfite has been" included.
It has been found, according to the present invention, that the use as a flotation reagent, of a thiazole compound with the addition of a soluble sulfite gives excellent results not attained by the use of either of the substances alone or in other combinations.
This invention is for a process of concentrating, by flotation, ores and minerals containing lead sulfide with or without zinc sulfide, and comprlses subiecting the ore in I the form of a pulp to 'a flotation operation in the presence ofa thiazo'le compound and a soluble sulfite.
As a specific example of carrying out the flotation operation according to the presentinvention, the following procedure may be used Using Sullivan Mining and Concentrat; ing Company ore, I grind 500 grams of the Lore with 350 cc. of water and .75 grams of sodium carbonate iii a ball mill for one-half hour. The mixture isjthen diluted to 40% solids, and to this pulp is added a sodium salt of mercapto-benzo-thiazole (.03 pounds per ton of ore), pine oil (.08 pounds per ton),[
and sodium hyposulfite .40 pounds per ton) The entire mixture is preagitated or conditioned for one minute. Following this the pulp is diluted to allow circulation and froth formation. A lead rougher concentrate froth is removed for three minutes. At the end of the lead period copper sulfate is added in the proportion 'of one pound per ton, and the agitation is'continued for one-half minute. Additional sodium salt of mercaptobenzo-thiazole is added-"in the proportion of .12 pound per ton and the flotation operation Many other NEW JERSEY, ASSIGNOR 'IO E. I. DU DE mom & OOIPANY, 0]!

It is also found that by using the sulfite in the flotation operation the lead concentrate is much cleaner in that it contains much less foreign matter than is the case when the sulfite is not used.
. The following thiazole compounds are some which have been found of value in carrying out the flotation operation of the present invention: mercapto benzo thiazole, 1gnercapto-3-methyl-benzo thiazole, mercapto naphthyl thiazole,'benzo thiazole di: su'lfide, zinc mercapto benzo thia'zole, sodium mercapto benzo thiaole', potassium mercapto benzo thiazole, calcium mercapto benzo thiazole, zinc mercapto-3-methyl benzo thiazole and benzo thiazole mono-sulfide.
It has been found that a frothing'agent is generally necessary in carrying out the flotations according to the present invention.-

After removal of the lead su de, the zinc sulfide can, in general, be floated by adding to the fiul copper sulfate or some other agent w ic destroys the deadening action of the sulfite. It is also usually necessary to add more of a'collecting agent and a frothin gent. v
the case of ores containing, in addition to the sulfides of lead and zinc, iron sulfide, the latter malyi be floated by a further addi tion of a co ecting a nt and a frothing agent to the tailin om the zinc sulfide flotation.
The amounts of flotation agent and soluble sulfite which are required to obtain the best difl'erential flotation results will depend largely upon the character of the ore treated, an may va within wide limits. Any suitab e soluble sulfite may be used 1n carrying out the process but it has been found that the alkali metalsulfites, and particularly sodium sulfites such as sodium hyposulfite are valuable because of their ready availability and comparative cheapness.
Any suitable and desired variations may. made in details of the process, or in the specific substances used and the conditions under which they are used," without departmg from the spirit and scope of the present invention. a
