Description
Uppfinnare: G T Lundgren Huvudpatentet 160 363 avser ett fOrfaringssatt vid framstallning av titan genom reduktion av en titanforening, foretra.desvis titantetraklorid, med ett metalliskt reduktionsmedel, yilket fOrfaringssatt kannetecknas darav, att titanforeningen i inert atmosfar nedfores i en smalta besthende av en blandning och/eller legering av magnesium och/eller natrium med flagon av metallerna bly, zink, tenn, i sadan mangd, att av magnesium och/eller natrium utreducerat titan loses i den aterstaende metallen under bildning av en smalta, som liar stone volymvikt an yid utreduceringen av titanet bildad ovrig omsattningsprodukt, t. ex. metallklorid, sã att denna i huvudsak samlar sig ovanpã metallsmaltan, varifran den avlagsnas, t. ex. genom skumning eller avsugning, under det att titanet, som gatt i fling i metallsmaltan, pa godtyckligt satt utvinnes ur denna. Inventor: GT Lundgren The main patent 160 363 relates to a process for the production of titanium by reduction of a titanium compound, preferably titanium tetrachloride, with a metallic reducing agent, which process is characterized in that the titanium compound is dissolved in an inert atmosphere and or alloying of magnesium and / or sodium with flaking of the metals lead, zinc, tin, in such an amount that titanium de-extruded by magnesium and / or sodium is dissolved in the remaining metal to form a melt which gives stone bulk density by the de-reduction of titanium formed other trading product, e.g. metal chloride, so that it mainly accumulates on top of the metal malt, from which it is deposited, e.g. by foaming or suction, while the titanium, which has flake in the metal malt, is arbitrarily recovered therefrom.
For utvinning av titanet ur metallsmatan kan man exempelvis ga tillvaga sá, att den som losningsmedel anvanda metallen, t. ex. bly, avlagsnas genom vakuumdestillation. Enligt en utforingsform, som foreslas i huvudpatentet, kan titanet utvinnas ur metallsmaltan genom segring. Harvid kan man fOrst lata bly-titanblandningen svalna pa sadant salt, att storsta mangden titan segras ut och sedan overskottsmdogden av flytande bly avlagsnats, kan ytterligare en del bly pressas ur den segrade produkten. Resterande My kan sedan avlagsnas ur denna genom vakuumdestillation. For extraction of the titanium from the metal feed, one can, for example, make sure that it uses the metal as a solvent, e.g. lead, removed by vacuum distillation. According to one embodiment, which is proposed in the main patent, the titanium can be recovered from the metal malt by victory. In this case, the lead-titanium mixture can first be allowed to cool on such a salt that the largest amount of titanium is excreted and after the excess liquid of liquid lead has been removed, a further part of the lead can be pressed out of the defeated product. The remaining My can then be removed from it by vacuum distillation.
Fiireliggande uppfinning avser en andamalsenlig behandlingsmetod vid utsegring ay titan ur bly-titansmaltan, varigenom ett relativt dyrban vaku.umdestillationssteg kan undvikas. The present invention relates to a disposable treatment method for removing titanium from the lead titanium malt, whereby a relatively expensive vacuum distillation step can be avoided.
Forfaringssattet enligt uppfinningen bestar dari, att det utsegrade titanet, som innehaller bly, forsattes t. ex. satsvis med reduktionsmetall sa att blyet loses av reduktionsmetallen, vilken behead-ling lampligen fOretages i ett separat karl. Behandlingen skall utfOras vid en temperatur, som overstiger reduktionsmetallens och blyets smdltpunkt, dvs. yid anvandning av magnesium som reduktionsmedel yid en temperatur Over magneslums smaltpunkt och yid anvandning ay natrium som reduktionsmedel vid en temperatur Over Myets smaltpunkt, och den erhallna lesningen, dvs. smaltan av magnesiumbly eller natriumbly, skall avskiljas frail titanet och aterfOras i processen for reduktion ay ytterligare en mangd titanfOrening. Behandlingen upprepas, tills man erhaller titan av onskad renhetsgrad. The process set according to the invention consists in that the excreted titanium, which contains lead, was continued e.g. batch of reduction metal so that the lead is released by the reduction metal, which treatment is suitably carried out in a separate vessel. The treatment must be carried out at a temperature which exceeds the melting point of the reduction metal and lead, ie. yid use of magnesium as a reducing agent yid a temperature Over the melting point of magnesum and yid use of sodium as a reducing agent at a temperature Over the melting point of Myets, and the reading obtained, ie. the melt of magnesium lead or sodium lead, shall be separated from the titanium and recycled in the process of reduction with a further amount of titanium compound. The treatment is repeated until titanium of the desired degree of purity is obtained.
Enligt en utfOringsform av processen kan man ga. tillvaga sa, att den vid reduktionsprocessen erhallna metallkloriden elektrolyseras, och att den darvid erhallna reduktionsmetallen anvande,s for behandling av den utsegrade titanprodukten pa angivet satt. Man kan aven fOrfara sa, att endast en del ay metallkloridsmaltan underkastas elektrolys pa detta satt, under det att aterstoden elektrolyseras under anvandning av bly som smaltkatod och att den yid elektrolysen bildade blandningen eller smaltan am reduktionsmetall och bly direkt aterfores till reaktionskarlet. I bada fallen fores salunda reduktionsmetallen i ett slags kretslopp I processen. According to an embodiment of the process, one can give. ensure that the metal chloride obtained in the reduction process is electrolysed, and that the resulting reduction metal is used, for the treatment of the decomposed titanium product in the manner indicated. It can also be said that only a portion of the metal chloride malt is subjected to electrolysis in this way, while the residue is electrolyzed using lead as the melt cathode and that the mixture formed by the electrolysis or the melt of reduction metal and lead is returned directly to the reaction vessel. In both cases, the reduction metal is thus fed into a kind of cycle in the process.
Behandlingen i de olika behandlingsstegen enligt uppfinningen genomfores givetvis liksom reduktionsprocessen enligt huvudpatentet under Adana betingelser, att oxidbildning eller bildning am icke onskvarda kvaveforeningar icke kan aga rum, dvs. i en skyddsatmosfar ay en lamplig inert gas, t. ex. argon. The treatment in the various treatment steps according to the invention is of course carried out as well as the reduction process according to the main patent under Adana conditions, that oxide formation or formation in non-adverse nitrogen compounds can not take place, i.e. in a protective atmosphere ay a suitable inert gas, e.g. argon.
