Many of these deposits also contain a certain amount of.uranium and thorium which cause aamma anomalies in the deposits, Sometimes uranium and thorium minerals are paragBn6tically associated *ith'the'.minerali a tion of rare and disperse elements, such as with beryllium and columbite tantalite in pegmatites, with beryllium and wolframite in greisenizations; sometimes the uranium and thorium minerals themselves such as pyrochlol"e lovtschorrite, fergusonite, monazite, xenotime, etc. are carriers of the rare elements. Besides, uranium and thorium may occur as isomorphous Card 1/3 Prospecting For Rare and Disperse Elements S/172'60/013/003-4/001/002 With Radioactive Methods B002//BO617 constituents in the gangue and in the accessories like in apatite, sphene, zircon, fluorite, and others. The magmatogenous deDOSitS were divided according to the type of mineralization and the radiometric properties: a) Premagmatic type: mineralization consists in finely distributed loparite, lovtschorrite, dysanalyto or knopite,. Thorite, lovtschorrit'?. otc.are radioactive minerals. The anomaly occurs locally and isometrically. b) Post-magnatic type: The mineralization is related to late displacement processes, especially to albitization. The mineralized material consists of zircon (as cyrtolite and malacon% pyrochlore, polycrase or f;rgusonite, columbite. The radiometrical anomaly clearly follows the zone of albitiza- tion. c) Third type: post-magmatic deposits which are connected with ultra- basic alkali rocks, Carbonatites are mineralized; pyrochlore and hatchettolite as well as carbonates and fluocarbonates of the rare earths are found. The following r0ioactive minerals are found; thorianite, monazite, and zircon. The nomaly decreases in the direction from the center to the periphery of the intrusion, Granite pegmatites show only local accumulations of uranium and thorium minerals. Pneumat;clytic-hydrothermak deposits could be observed by the enrichment of uranium and thorium- Some Curti 2/3 Prospecting For Rare and Disperse Elements With Radioactive Methods S/172/60/013/003-4/001/002 B002/BO067 general remarks are made on the radiometric determination., Finally.. it is said that the following depos;ts have 91ready been determined by means of radiometric methods: diamondObauxite,Pphosphorite, titanium, copper- bearing sandstones, ~I-ack shate-,--anT-others.

Ed.: N.T. Gofman; Ed. of Publishing House: L.N. Sarkisyan;. Tech. Ed.: A.R. ToduA. PURPOSE: This book Is intended for metallurgists. COVERAGE: -This collection of papers deals wi-t)a toe problem of ob- taining high-"urity chromium and the problem of producIng pure raw P materials from i4hich the metal itself is obtained. The investiga- tions reported in this volume were-conducted between 1947 and'1957 at the Institut prikladnoy khimii I clektrokhimii AN'Grazinskoy SSR (Institute of Applied Chemis~ry and'Electrochemistry, Academy of Sciences Gruzinskaya:SS 'R). The most detaJAe"d studies,in the collec- tion are those dealing with the elect.r.ol-ysis of sulfate solutions and with methods of obtltining raw materials for the process. ItIs Card 1/9 Hydroelectrometallurgy of Chromium (Cont.) SOV/3462 claimed that more,than a decade of investigation, testing of flow- sheets and eldctrolytic-tank'designs utilization of Soviet and non- Soviet data, and reverification of I Published results obtained at the pilot plant of the U.S..Bureau of Mines have led to the development of a definite., and to Some extent original, method of obtaining high- purity chromium. Choice of a simple, economical flowsheet required the study of methods for obtaining and Purifying compounds of triva- lent chromium. The most acceptable method, technologically, has proven to be a two-stage refining of ferrochrome. It is described in the Introduction by R.I. Agladze. Compounds of hexavalent cj~rom'_ ium are obtained in the first stage by direct electrochemical dissolution of carbon-containing ferrochrome; in the second stage, electrolysis of the chromium salts, reduced to the trivalent state, is carried-out. The.method is 'considered significant in view of the possibility it affords~of using not only standard ferrochrpme, but also ferrochrome with a-higb content Of Impurities and a low chromium content. This feature makes it feasible to use low-grade chrome ores. Studies are made of the anodic dissolution of 11'erro- chrome in sulfate, carbonate, alkaline, ammonlacal, and chromate solutions, The following methods of reducing hexavalent chromium' Card 2/9 Hydroelectrometaliurgy of Chroml~,.;_m fContj 30V/'1462 compounds are investigated: the electroohemical me-thod, the action Of sUlfur-c-ontain-ing substances, and the action of materials con- taining cellulose. Also investigated are methods of purifying the chromium compounds of Iron, the Principal Contaminant, by fractional precipitation of hydroxides, direct precipitation of iron hydroxide, or solution of ferrochrome In alkaline, carbonate, and other elec- trolytes. One of the Possible Processes of obtaining high-pdrity chrorqe hydroelectrometallurgically is presented with an accompanying flov~dheet. The principal comp*onentb art chromium sulfate, ammonium sulfate (or chrome ammonium alLun), and a certain quantity of biva- lent chromium ions, which form during the electrolytic process and whose preservation at a definite concentration is necessary for stabilizing the process. Carbon-containing ferrochrome is used as the raw material for the production of chrome --anmoni'um. alum. Ammo- nium, bichromate is obtained by anodic dissolution of ferrochrom-e in reusable solutions at a definite PH value. Iron hydroxide and other insoluble residues are filtered off. industrial water is used for preparing new portions of the electrolyte. The electrolyte, a so- lution of ammonium bichromate or a mixture of bichromate a:nd chro- mate., is reduced in the presence Of Sulfuric acid with iron filings Card 3/9 Hydroelectrometallurg,,r of chr(~,jmjum (Cont,) 307/3462 or other reducing agents to the complete Coliversion of bichromate to chromium sulfated The eleletrolyte is then transferred to crystal- lizing tanks for crystallization of the-,chrom .e WaOnium alum. A small quantity of catholyte, oontaining bJvalent chromium ions, is ad'ded to the crystallizing tanks to speed up crystallization. The acidi- mother liquor is returned to the section for the reduction of bichromate, and the chrome ammonium alixn is dissolved for tile feeding of the catholyte of the chromium tanks, An anolyte, & mix- ture Of chromic and Sulfuric acids, is also added to the section for reducing, where it Is reactivated. A trial run on an industrial scale has shown that the process may successfully compete with the production of chromium by aluminum reduction and demonstrated the high quality of the products The studies in this collection and the proposied method of Producing high-purity chromium are considered by the staff of the Institute of AP'P'led Chemistry and Electro- chemistry as Just one stage In their-Lwark. Investigations of other methods will be reported in a later volume. The investigators are studying the Possibility of obtaining chromium in a single-stage electrolysis involving solution of ferrochrome and cathodic precipi- tation of the Pure metal in a single tank.

Pequil for reactions (1) and (2) was determined by the boiling method (cf. Gvelesiani, G. G., et al. Trudy Gruzinskogo in-ta metallurgii, vol. XIV, 1965). Briquetted charge (molar ratio La(Ce)/Yb203 = 2.5) was heated at 850-1150*C and the evaporation rate of Yb was measured 6-8 times at various temperatures; where- upon a curve of the rate of weight loss of the residue was plotted. On this basis it was established that, within the investigated range of temperatures, the exp(tri- mentally determined values of the Gibbs function for the thermal reduction of Yb203 by means of La and Ce differ in both cases from their theoretically calculated count- erparts. A possible explanation for this discrepancy is that at present the values of many of the thermochemical quantities necessary for the calculations have not yet been established for most rare-earth metals and their compounds.

Soobshcheniya, v. 41, no. 3, 1966, 657-664 TOPIC TAGS: samarium compound, lanthanum, powder metallurgy, chemical kinetics ABSTRACT: A method for the thermal reduction of samarium oxide powder by lanthanum in a vacuum is described. Briquets (15 x 3 x 3 mm) were pressed f7-om powder mixtures of B-SM203 and La of 99.5% purity and reduced in vacuo by heating to 12000C. The equi librium partial pressure of Sm vapor and the isobaric-isotherml potential were given as functions of temperature by the following equations: 8.21 - 11250 (1225-14730K) lgPMM = T and AZO = 102940-48.77T (1225-14730K). T The evaporation of Sm limited the speed of the process in the early stages, while dif fusion of the reactants through the solid reactant product La203 limited the speed in L A ,ACC NR: AP6021712 the latter stages. By examining the Sm yield as a function of the molar ratio La/ /SM203, the optimum charge was determined to be La/Sm203 = 2.75, for which the Sm yield was between 93 and 66% at 12000C. The following optimum process conditions are: temperature--12000C, reduction time--l hr, briquetting pressure-2500 kg/=Z, sizek
