Description
<EMI ID=1.1>
Le brevet principal se rapporte à un procède pour
<EMI ID=2.1> <EMI ID=3.1>
de telles matières revêt une grande importance Industrielle.
<EMI ID=4.1>
tions de ce liftai, par exemple de .attes brutes de cuivre ou de cobalt.
<EMI ID=5.1>
présent sont celles qui contiennent non seulement du fer et du soufre mais aussi d'autres métaux lourds ( indépendamment
<EMI ID=6.1>
<EMI ID=7.1>
la matière première contienne aussi peu de soufre que possible. S'il est difficile de concasser le produit solidifié
<EMI ID=8.1>
peut tourner la difficulté en granulant ce produit alors qu'il se trouve encore à l'état fondu.
Dans la mise en oeuvre de ce procède on peut également employer des pressions très elevées, par exemple de 1000 atm. ou même plus. Une élévation de la pression se traduit par une diminution du temps de réaction. La tempéra-
<EMI ID=9.1> <EMI ID=10.1> <EMI ID=11.1>
soufre, peut à nouveau être fondu avec de la grenaille de
<EMI ID=12.1>
pour 70 parties de fer, après quoi on procédera à nouveau au traitement par l'oxyde de carbone en vue de la formation de ferro-carbonyle, et ainsi de suite, jusqu'à ce aue la proportion d'impuretés provenant de la grenaille soit devenue si forte qu'elle se manifeste de façon gênante pour la formation du carbonyle.
EXEMPLE 2
<EMI ID=13.1>
parties de sulfure de cuivre. Traiter par l'oxyde de carbone dans les conditions indiquées à l'exemple 1 le produit de fusion réduit en grains de 10 mm. de grosseur. Le fer se transforme ainsi en ferro-carbonyle; quant au résidu? on peut le soumettre à nouveau à l'opération.
Ce procédé peut convenablement s'appliquer à
<EMI ID=14.1>
tient. Le résidu sera ensuite traité en vue d'en retirer le cuivre.
<EMI ID=15.1>
brute de cobult. S'il se forme un peu de cobalt-carbonyle en outre du ferro-carbonyle on le séparera de ce dernier par distillation.
<EMI ID=16.1>
<EMI ID=17.1>
de pyrite incomplètement grillé et granuler le produit de fusion dans de l'eau. Traiter ensuite la masse par l'oxyde
<EMI ID=18.1>
de 180 à 220[deg.]C. En poursuivant le traitement pendant 8 heures
<EMI ID=19.1>
L'oxyde de carbone est alors employé en cycle fermé. La
<EMI ID=20.1>
<EMI ID=21.1>
traitement le residu de réaction est prêt pour une nouvelle opération de grillage.
<EMI ID = 1.1>
The main patent relates to a process for
<EMI ID = 2.1> <EMI ID = 3.1>
such materials are of great industrial importance.
<EMI ID = 4.1>
tions of this liftai, for example of raw copper or cobalt.
<EMI ID = 5.1>
present are those which contain not only iron and sulfur but also other heavy metals (independently
<EMI ID = 6.1>
<EMI ID = 7.1>
the raw material contains as little sulfur as possible. If it is difficult to crush the solidified product
<EMI ID = 8.1>
can overcome the difficulty by granulating this product while it is still in the molten state.
In the implementation of this process, it is also possible to use very high pressures, for example 1000 atm. or even more. An increase in pressure results in a decrease in reaction time. The temperature
<EMI ID = 9.1> <EMI ID = 10.1> <EMI ID = 11.1>
sulfur, can again be melted with
<EMI ID = 12.1>
for 70 parts of iron, after which the treatment with carbon monoxide for the formation of ferro-carbonyl will be carried out again, and so on, until the proportion of impurities coming from the shot is become so strong that it manifests itself in a way that hinders the formation of carbonyl.
EXAMPLE 2
<EMI ID = 13.1>
parts of copper sulphide. Treat the fusion product reduced to 10 mm grains with carbon monoxide under the conditions indicated in Example 1. of size. The iron is thus transformed into ferro-carbonyl; as to the residue? it can be subjected to the operation again.
This method can suitably be applied to
<EMI ID = 14.1>
is holding. The residue will then be processed to remove the copper.
<EMI ID = 15.1>
cobult brute. If some cobalt-carbonyl is formed in addition to the ferro-carbonyl, it will be separated from the latter by distillation.
<EMI ID = 16.1>
<EMI ID = 17.1>
incompletely roasted pyrite and granulate the melt in water. Then treat the mass with the oxide
<EMI ID = 18.1>
from 180 to 220 [deg.] C. By continuing treatment for 8 hours
<EMI ID = 19.1>
The carbon monoxide is then used in a closed cycle. The
<EMI ID = 20.1>
<EMI ID = 21.1>
treatment the reaction residue is ready for a new roasting operation.
