Tsvetnaya metal- lurgiya 1960, Nr 1, !)p 50-156 (USSR) ABSTRACT: Cobalt ores of the Soviet Union are characterized by low Co content. Conside?able difficulties encountered in dressing are due to very i-ine dispersion of Co minerals. This article deals wLth a laboratcry test of dressing ore of this type from one of the deposits in the Kras- noyarsk region (not iamed). The size of Co mineral in- ClU,2,ions ranged from 0.001 to 0.1 mm ininus mesh with a total content of 0.036% Co in the ore. The other com- ponents wereg (%) 65.0 S1021 13.7 Al 2032 3.4 Fe, 3.6 CaO, I a.8 Mgo, 0.05 Mn, 1.,5 S, 0.12 Sb, 1.6'3 As, 0.88 Cu, 0.23 Card 1/17 Ni, and 37.4 g/ton A~. About 20% cobalt content Beneficiation of Poor Copper-Cobalt Ore 77718 by Hydrometallurgical Processes S()V/149-60.-2-7/27 consisted of oxidized minerals and BO% arsenides and sulfoarsenides. The mine::,alogical analysis was made by A. I. Vitushkina and i-- disclosed the presence of safflorite, smaltite, glaucodote, aeritrite, tetrahe- dritE~ tennantite, chalcopyrite, covellite, malachite, rammelsbergite, chloant-Ite, annabergit, and silver. The dressing tests c)mprised the following stages. The first determined the advantages of collective vs selective flotation, each having its own set of re- agents. Collective flotation was given preference while selective flotation produced concentrate richer in Co (1.22 vs 1.01%), Co losseo in tailings were much higher (16.7% C) content in ore vs 10.6%). After deciding in fa,ior of collective flotation, ~-wo variations were tried, (a) with one-stage crush- j.ng, three reruns, and selective flotation of the copper-cobalt concentrate; (b) with two-stage crushing, three flotations, selective flotation of the first concentrate, and three reruns of the cobalt concentrate Card 2/7 Alternative (b) proved to be best and resulted in a 10~-. Beneficiation of Poor Copper-Cobalt Ore T'17TI8 by Hydrometallurgical Processes sov/1 4 9 -Q,'o - i --7//p7 higher rate of Co eytraction. Folloi-.,ing details of this method are given. The first crushing reduces 45% ore to minus mesh 0.074 mm; in the second crushing this figure is raised to 80%. Crushing is done with soda addLtion (250 g/ton). During the first flotation 100 g/ton butyl xanthogenate and 30 g/ton pille oil are added; during thc- second and third flotation, 50 g/ton sodium sulfide, 2-00 g/ton amyl xanthogenate, and 70 g/ton foaming agent D (not specified). Total flotation time is LO min. During recleaning operations water glass (500 g/ton' and amyl xanthogenate were added. To eli- minate excessive flotation reagents carbon (100 g./ton) was introduced into selective flotation as well as lime (8 Irg/ton) as a depressant for cobalt minerals and pyrite. Cobalt extraction according to this schedule reached 70.068%, and the concentrate contained 1.17% Co. Selective flotation methods as su~:;gested by S. I. Krokhin and B. D. Nelcrasov and finishing by gravitation as used at the Silence plant, Canada, has failed to produce Card 3/7 satisfactory results. Subsequently, hydrometallic Beneficiation of Poor Copper-Cobalt Ore by Bydrometallurgical Processes 77718 sov/149-6o-i-7/27 methods were adopted as. shown in the proces3 flow chart below (Fig. 6). Cobalt concentrates as obtained from flotation were 9 roce:;sed in folloL-.-ing stages: oxidizing roasting at 500 , su'.fatizing roa2ting with sodium bisulfate at '7000 for 2 hrs, leacKing by water, and weak sulfuric acid solution. Undc-r these conditions 90 to 95% available Co passes intc the solution. The latter is separated 1'rom iron and copper by soda: Fe is precipitated at p11=4.2, Cu at,~H-5.2. Cobalt is precipitated by soda (70 mg/lite or sodium sulfide. The final product contains 12-14% Co at a 84-85% rate of extraction from the concentrate. These processes are incorporated in the I'low chart (see Fig. 6). The Co extraction rat.-e from ore amounts to 61..C~G, that of Cu is 78.4%6. The conclusions contain a short recapitula- tion of the above dal;a. There are 4 tables; 6 fi-,'lres; 5 references, 3 Soviet, 1 Canadian, I U.K. The Ca,iadia and U.K. references are D. C.

St 20. The C14 isotope was introduced into the specimens by means of anneal- ing them in vacuum, at a temperature of I I OOOC for a period of four hours, together with BaC03 enriched with C14. After annealing, the average size of a pearlitic region amounted to approximately 65~1 and that of a ferritic field.to 11511 . Heating rates (HR) of 30, 1:50, and 230 degrees/second were employed in the region of phase transform- ations. At all HR the quenching was performed at temperatures rang'. Card 1/2 ing from 800 to 13000. Photometric evaluation of the radiograms SOV/1 37-58- 11-23456 A Radiographic Investigation of Nonuniformity of Martensite Produced During (cont.) revealed that the nonuniformity of C distribution at all quenching temperatures in,- creases with increasing HR. A fully hardened structure may be obtained only at a temperature of 11000 or above. During quenching from a temperature of 9000 the concentration of C in the central portions of the formerly pearlitic regions amounts to 0. 570/o at an HR of 300/sec and 0. 750/o at an HR of 1300/sec. Almost complete equalization of the C concentration was attained only after quenching from a temper- ature of 13000 at a minimal HR of 300/sec; at an HR of 2300,/sec, the C cDncentra-- tion in the central portions of the formerly pearlitic regions amounted to 0. 580/0 and in the ferritic interstices to 0. 070/0 only. Regardless of the HR the intensity of dif- fusion processes is greater at 800-11000 than it is at 1100-13000 owing to a reduc- tion in the gradient of C concentration at temperatures ranging from 1100 to 13000.

In order to prove the structure of the urethans their hydrolytic cleavage reaction was investigated more thoroughly.

The formation of these products may take place as follows: organosilico urethane reacts with very small quanti- ties of water in the alcohol and forms dicarbamic acid and tri- alkyl hydroxysilane. The unstable dicarbamic acid decomposes into CO 2 and diamine while silane reacts with alcohol and forms the trialkyl-substituted ester of orthosilicic acid (Scherie 3). In order to prove this mechanism it has to be found out whether the trialkylhydroxysilanes can react with alcohols (without catalysts as well). The experiments showed that these silanes react with alcohols in the presence of diamine, but also without diamine, according to the scheme R3'SiOH + HOR" R3'SiOR1' + H20 . The reaction was carried out with methyl-, propyl-, butyl-, and isoamyl alcohol. The Card 2/3 properties of the new compounds are given in the table.

TE'LEj E-yzithesis of Some Triethyl Siloxy Alkoxy Titanes PERIODICAL: Loklady Akademii nauk SSSR, 1959, Vol 127, Nr 5, PP 1014 - 1015 (USSR) AB&TRACT: The compounds mentioned in the title have hitherto remained unin- vestigated, The trialkyl (aryl) siioxy groups have considerable hydrolytic stability in the ietrakis-[trialky'.I(aryl)sil.oxyltitanes which is much higher than tha 't of the alkoxy groups bound-t1o tLtanium. It is therefore of interest to investigate the proper- ties uf compounds containing simultaneously trialkyl siloxy- and alkoxy groups. Since the method described by the first author (Ref 1) is difficultly acoessible the authors investigated tl'ie pasnibility of the synthesis mentioned in the title by a direct interaction of triethyl silanol with butyl orthotitanate or pro- pyl orthotitanates. In contrast to the data from publications (Ref 3) according to which the reaction between butyl orthotita.- nate and triphenyl silanol is said to lead to a complete sub- stitution of all butoxy groups by triphenyl siloxy groups the Card, 1/2 authors proved that in the case of the here applied substances, Synthesis of Some Triethyl Siloxy Alkoxy TitaneB SOV/2o-127-5-22/58 in the presence of metallic sodium as catalyst, the reaction does not only proceed in the direction of the formation of tetrakis (triethyi-siloxy) titanium. Also products of differ- ent degrees of substitution are formed in this connection. This depends on the ratio of the reaoting components. In the course of the investigation of the montioned reaction (see Scheme) tri-(triethyl-siloxy)-butoxy.-titanium (46,,16 of the theoretically computed value), di(triethyl-siloxy)-dibutoxy titanium (345A), d:~.(triethyl-siloxy)--,Lipropoxy-titanium (21Y0) were isolated.
