Description
Reiuued June 30, 1931 UNITED STATES PATENT OFFICE INDIANA, ASSIGNORB '10 PETER. C. REILLY, INDIANAPOLIS, INDIANA ORE I'LO'I'ATION PROCESS Ho Drawing. Original No. 1,765,302, dated June 17, 1930, Serial No. 321,269, filed November 22, 1928. Application for reissue filed October 15, 1930. Serial No. 488,986.
The present invention relates to the froth flotation of minerals from ores, by the use of novel flotation ingredients, and is based upon our discovery that the reaction product of silicon sulfide with a grou of substances, of which sodium alcoholate urnishes the typical example, produces a series of bodies having valuable floatation properties, when used in conjunction with a frothing agent, for the separation of minerals from ores.
The following reaction illustrates one reaction which may take place, sodium ethylate being shown in this reaction, but it will be understood that the methylate as well as its homologues and other substances as noted below, can be similarly employed.
It is further to be understood that the other alkali metal compounds such as the potassium compounds may be also employed. It has also been found that absolute alcohol itself can under some conditions be sub-' stituted for the ethylat'e, producin the corresponding acid, in accordance wit the following reaction, (representing one of the re actions which appears to take place).
The above substances namely thio-silicooxy-ethyl sodium sulfid and thio-silico-oxyethyl-thio acid are to be regarded as typical of the alk 1 compounds of the class mentioned. Of these compounds the ethyl derivatives have been found to be very satisfactory, and it is also found that the methyl compounds can be used. There appears to be no particular advantage in using the higher alkyl compounds such as propy and butyl, which are more expensive than the ethyl compounds but they are also suitable.
In place of the ethyl alcohol and sodium ethylate in the above examples, sodium cresylate or phenate, sodium mercaptol, sodium cyclohexanol, mixed sodium salts of tar acids, also the cresol, phenol, tar acids, hydrogenated phenols (e. g. cyclohexanol), mercaptol, or mixtures thereof, can be used.
It will be understood that sodium compounds are herein referred to, but obviously the potassium, calcium, barium or strontium compounds can be used, the group of metals hereinafter being referred to in the term alkali-forming metal.
We have indicated one type of reaction product that may be obtained by the reaction of silicon sulfide (SiS on the above classes of substances. We do not, however, limit ourselves to any type of reaction or reaction products. The products formed may be characterized as thiosilicic acid organic compounds. In some cases, when mercaptols are used, say sodium ethyl mercaptol,
a compound Gan; 2m
may be formed, and that when sodium cresylate is "used, a compound may be formed, and when the hydroxy compound, say phenol is used, the com ound OIHI may be formed.
, hese compounds may be considered as mono-esters of thiosilicic acid and examples are the thio-silico-sulf-eth 1 sodium sulfide, the thio-silioo-oxy-tolyl sodium sulfide and the thio-silico-ox -phenyl-thio acid compounds of which the ormulas have just been recited.
Thus it is seen that in Formula (I) given above, the O can be replaced by'S, and that the 0 H, (133811 be replaced by another alkyl group or y an aryl oup or an aral 1 group and that the sodium can be re la d y hydrogen (as in Formula (11)) or other alkali-forming metal.
In the preparation of the flotation reagent of our invention, nerally stated it is sufficient to select t e desired organic compound and to react thereupon with silicon sulfide in any desired proportion, and at a temperature sufliciently high to bring about a ready reaction, and with agitation and tri- I00 turation of the reaction mixture. Many of the reactions have been found to occur at ordinary room temperature.
By reacting with ethyl chlorid on the salt OCIHI ssi In place of the above mentioned compounds, various organic derivatives of other silicon-sulfur compounds may be used as flotation agents, notably silicon chlor-hydrosulfid, SiChSI-I or the salts or esters thereof. The silicon chlor-hydrosulfid can be prepared in known manner by reacting on silicon chlorid with H 8 at about a red heat. The corresponding fluorin compounds also can beem loyed.
In the otation or ores by the use of the above products, the said products may be used in froth flotation, in conjunction with a rot-hing a cut, such as pine oil or a tar oil distillate. he said reagent and the frothing agent can be thoroughly mixed with the ore pulp, for example in a tube mill or other device in which the ore pul is being produced, and the amount of t c said reagent may be varied between wide limits depending upon the nature of the ore under treatment. For many cases about 0.05 to 0.2 pounds of the silicon-solfur-containing reagent er ton of ore will be found satisfactory. he pulp is then subjected to the or dinary aeration flotation or froth flotation) operation, producing a cam carrying the sulfide mineral from the ore. The flotation can be conducted in a neutral, alkaline or acid circuit, as desired.
We claim:
1. A process which com rises subjecting ores to froth flotation in t e presence of a.
