Description
Procédé d'extraction<B>de</B> titane<B>de</B> ses minerais avec production concomitante<B>de</B> produits azotés. La présente invention se rapporte<B>à</B> un procédé d'extraction de titane de ses minerais avec production concomitante de produits azotés. Ce procédé est caractérisé en ce qu'on mélange, aux minerais, du charbon et un composé métallique, chauffe en présence d'azote, puis traite le mélange<B>à</B> la vapeur d'eau de façon<B>à</B> obtenir des produits azotés et du titanate, que l'on sépare du mélange par dissolution et transforme en oxyde de titane dont l'on tire le titane par réduction.
Ce procédé petit être mis en oeuvre par exemple de la façon suivante: Au minerai titané, on mélangera du char bon et un sel ou oxyde métallique, alcalin, alcalino-terreux ou autre (Par exemple du carbonate de soude). L'ensemble sera réduit en poudre. Les quantités<B>à</B> employer sont variables suivant les teneurs<B>du</B> minerai.
On cite,<B>à</B> titre d'information, les proportions suivantes: Fer titané <B>à</B> 40 % TiOl <B>. .</B> 1000 kg Carbonate<B>de</B> soude<B>. . . . 750 kg</B> Charbon<B>. . . . . . .
1000 kg</B> Le mélange sera chauff6 en milieu azoté <B>à</B> une température qui ne dépassera pas <B>1850 0 C.</B> Le mélange absorbera l'azote et don nera des azotures, carbures, carboazotures etc., qui seront ensuite soumis<B>à</B> l'action de la vapeur d'eau<B>à</B> une température ne dépassant pas<B>1800 0 C.</B> Il<B>y</B> aura dégagement d'am moniaque, d'acide cyanhydrique etc. Ces divers corps sont captés au moyen d'appa reils de lavage ou de condensation appropriés.
La masse ayant subi l'action de la vapeur d'eau contiendra une grande partie des métaux <B>à</B> l'état d'oxydes et le titane<B>à</B> l'état de titanate qui pourra être extrait par lavage<B>à</B> l'eau, aux acides et aux bases. La solution de titane sera ensuite précipitée pgr hydrolyse, par l'action des acides ou des bases.
Après lavage, filtration. dessication et calcination<B>à</B> haute température, on obtiendra Lin produit anhydre constitué par de l'oxyde de titane que l'on traite par un réducteur pour obtenir<B>le</B> titane.
Process of extraction <B> of </B> titanium <B> from </B> its ores with concomitant production <B> of </B> nitrogenous products. The present invention relates <B> to </B> a process for extracting titanium from its ores with concomitant production of nitrogenous products. This process is characterized in that one mixes, with ores, coal and a metallic compound, heats in the presence of nitrogen, then treats the mixture <B> with </B> water vapor in a <B> to obtain nitrogenous products and titanate, which are separated from the mixture by dissolution and converted into titanium oxide from which the titanium is obtained by reduction.
This process can be implemented, for example, as follows: With the titanium ore, good char and a metal, alkali, alkaline-earth or other salt or oxide (for example sodium carbonate) will be mixed. The whole will be reduced to powder. The quantities <B> to </B> to use are variable according to the <B> contents of </B> ore.
The following proportions are cited <B> for </B> for information: Titanium iron <B> at </B> 40% TiOl <B>. . </B> 1000 kg <B> soda </B> carbonate <B>. . . . 750 kg </B> Coal <B>. . . . . . .
1000 kg </B> The mixture will be heated6 in a nitrogenous medium <B> to </B> a temperature which will not exceed <B> 1850 0 C. </B> The mixture will absorb nitrogen and give rise to azides, carbides, carboazides etc., which will then be subjected <B> to </B> the action of water vapor <B> at </B> a temperature not exceeding <B> 1800 0 C. </ B > There will <B> there </B> be release of ammonia, hydrocyanic acid etc. These various bodies are captured by means of suitable washing or condensation devices.
The mass which has undergone the action of water vapor will contain a large part of the metals <B> in </B> the state of oxides and the titanium <B> in </B> the state of titanate which can be extracted by washing <B> with </B> water, acids and bases. The titanium solution will then be precipitated by hydrolysis by the action of acids or bases.
After washing, filtration. high temperature desiccation and calcination at <B> </B>, an anhydrous product consisting of titanium oxide will be obtained which is treated with a reducing agent to obtain <B> the </B> titanium.
