Fremgangsmåte til sulfatering av ikke-jernmetaller i findelte jern- eller andre malmer. Process for sulphating non-ferrous metals in finely divided iron or other ores.
Fremgangsmåten vedrorer å overfore ofte verdifulle side-metaller som Cu, Co, Ni, Zn osv., som befinner seg i findelte jernmalmer og som er skadelige for jernfremstillingen, til opploselige sulfater, mens jernet praktisk talt forblir fullstendig som oksyd<1>The process concerns the transfer of often valuable side metals such as Cu, Co, Ni, Zn, etc., which are found in finely divided iron ores and which are harmful to iron production, into soluble sulfates, while the iron remains practically completely as oxide<1>
FegO^. Fremgangsmåten kan også anvendes i forbindelse med andre malmer enn jernmalmer. FegO^. The method can also be used in connection with ores other than iron ores.
I praksis kan den sulfaterende rostingen gj<ennomfores f.eks. In practice, the sulphating roasting can be carried out, e.g.
i en hvirvelsjiktovn, i hvilken det er lett å beherske forholdene og temperaturen. Den sulfaterende rostingen har hittil blitt utfort bare ved bruk av sulfidholdige malmer, hvorved blant annet folgende reaksjoner foregår: in a fluidized bed furnace, in which it is easy to control the conditions and temperature. Sulphating roasting has so far only been carried out using sulphide-containing ores, whereby the following reactions take place, among other things:
De to sistnevnte reaksjoner, som er viktige for sulfateringen, kan gå i begge retninger og er sterkt avhengige av temperaturen og gass-sammensetningen. Det er blitt konstatert at på grunn av metallsulfatenes termiske dissosiasjon, ligger den mest egnede sulfateringstemperaturen på begge sider av 700°C, hvorved jernsulfåtets mengde forblir liten, og at en overskuddsmengde luft må anvendes i overensstemmelse med den teoretisk nodvendige, dvs. den mengde som kreves for oksydering av sulfidene og dannelse av metallsulfåtene. The two latter reactions, which are important for sulphation, can go in both directions and are strongly dependent on the temperature and gas composition. It has been established that due to the thermal dissociation of the metal sulphates, the most suitable sulphation temperature lies on both sides of 700°C, whereby the amount of iron sulphate remains small, and that an excess amount of air must be used in accordance with the theoretically necessary, i.e. the amount which required for oxidation of the sulphides and formation of the metal sulphates.
Idet alle de ovenfor nevnte kjemiske reaksjoner er sterkt eksotermiske, og idet det er av vesentlig betydning at temperaturen holdes konstant, er det svært nodvendig med en kontrollert avkjoling. På grunn av den adhesjonstendens som forekommer ved en sulfaterende rosting, er avkjolingselementenes anvendelse i selve hvirvelsjiktet vanskelig, på grunn av at disse elementers overflater ved lav temperatur prover å tilfeste seg stoffer som inneholder rikelig med jernsul-fat. I nuværende fremgangsmåter gjennomfores derfor avkjølingen direkte som en vanntilsetning til hvirvelsjiktet, delvis slik at jern-malm-konsentratet tilfores som et vannslam, delvis ved en direkte vanninnsproytning. Disse fremgangsmåter oppviser en lite formåls-tjenelig varmeokonomi, fordi avkjolingen hovedsakelig gjennomfores ved fordampning av vann og denne fordampningsvarme kan i praksis ikke gjenvinnes. Da ytterligere jernmalmkonsentrat innsproytes i ovnen oveni-fra som et vannslam, for tilveiebringelse av ensartede betingelser, avkjoles avlopsgassene derved utilborlig og forringer ytterligere prosessens varmeokonomi og forårsaker en kraftig sulfatering av jernet i det innforte materialet. As all the chemical reactions mentioned above are highly exothermic, and as it is of essential importance that the temperature is kept constant, a controlled cooling is very necessary. Due to the adhesion tendency that occurs during a sulphating roasting, the use of the cooling elements in the fluidized bed itself is difficult, due to the fact that the surfaces of these elements at low temperatures try to adhere to substances containing plenty of iron sulphate. In current methods, the cooling is therefore carried out directly as a water addition to the fluidized bed, partly so that the iron-ore concentrate is supplied as a water slurry, partly by a direct water injection. These methods show little useful heat economy, because the cooling is mainly carried out by evaporation of water and this evaporation heat cannot in practice be recovered. When additional iron ore concentrate is injected into the furnace from above as a water slurry, in order to provide uniform conditions, the waste gases are thereby unduly cooled and further deteriorate the heat economy of the process and cause a strong sulphation of the iron in the introduced material.
Fra norsk patent nr. 90 120 er det kjent å roste svovelkis From Norwegian patent no. 90 120 it is known to praise pyrite
i en hvirvelsjiktovn hvorved SC^-innholdet i avgassene holdes på et maksimalt nivå. Det tas her sikte på ved en avsvovlingsrosting å oppnå et svovelfritt oksydmateriale, mens det ved foreliggende fremgangsmåte foretas en sulfaterende rosting av visse metaller i en hvirvelsjiktovn. Videre er det fra tysk patent nr. 901 959 kjent en totrinns rostingsprosess av svovelholdig malm i en hvirvelsjiktovn, ved bruk av in a fluidized bed furnace whereby the SC^ content in the exhaust gases is kept at a maximum level. The aim here is to obtain a sulphur-free oxide material with desulphurisation roasting, while in the present method a sulphating roasting of certain metals is carried out in a fluidized bed furnace. Furthermore, from German patent no. 901 959 a two-stage roasting process of sulphurous ore in a fluidized bed furnace is known, using
et oksygenoverskudd. Hensikten er utelukkende å oppnå en fullstendig fjerning av svovel fra malmen-. Det tas således ikke sikte på å oppnå et sulfatert produkt. I tysk patent nr. 347 834 beskrives omdannelse av sulfidmalmer til sulfatform ved utforelse av rosting med et over-skudd av oksygen. Således behandles det ved rosting oppnådde oksydmateriale i medstrom med oksygenholdig rostegass i nærvær av jernoksyd, som fremmer reaksjonen mellom oksygen og svoveldioksyd til SO^ hvilket forårsaker en sulfatering av nevnte materiale. Råmaterialene er således forskjellige fra de som benyttes i foreliggende fremgangsmåte. Fra tysk patent nr. 598 333 er det kjent å foreta sulfatering av en stasjonær charge, omfattende forskjellige nikkel- og/eller kopperhold-ige råmaterialer, som på forhånd tilsettes nodvendig mengde svovel for sulfateringen. Prosessen foretas ved innforing av oksygen eller oksygenanriket luft under oppvarming. Istedenfor å benytte en stasjonær charge som på forhånd gis en bestemt sammensetning er foreliggende fremgangsmåte kontinuerlig og sjiktet i hvirvelsjiktovnen er i stadig bevegelse og chargens sammensetning reguleres ved innmat-ningen. an excess of oxygen. The purpose is exclusively to achieve a complete removal of sulfur from the ore. The aim is thus not to obtain a sulphated product. German patent no. 347 834 describes the conversion of sulphide ores into sulphate form by carrying out roasting with an excess of oxygen. Thus, the oxide material obtained by roasting is treated co-currently with oxygen-containing roasting gas in the presence of iron oxide, which promotes the reaction between oxygen and sulfur dioxide to SO 3 , which causes a sulphation of said material. The raw materials are thus different from those used in the present method. From German patent no. 598 333, it is known to carry out sulphation of a stationary charge, comprising various nickel- and/or copper-containing raw materials, to which the necessary amount of sulfur is added in advance for the sulphation. The process is carried out by introducing oxygen or oxygen-enriched air during heating. Instead of using a stationary charge that is given a specific composition in advance, the present method is continuous and the layer in the fluidized bed furnace is in constant motion and the composition of the charge is regulated by the feed.
Ifolge foreliggende oppfinnelse er det tilveiebragt en fremgangsmåte til sulfatering av ikke-jernmetaller, f.eks. Cu, Co, Ni og Zn, som befinner eeg i små mengder i findelte sulfidmalmer eller konsentrater, i en hvirvelsjiktovn under finregulering av temperaturen ved innsprøytning av vann direkte i hvirvelsjiktet, kjennetegnet ved at det oksydiske materialet, som er blitt rostet fra sulfidmalmen, tilsettes urostet sulfidmalm i en mengde på 0.05 - 1 ganger mengden av oksydisk materiale for tilveiebringelse av varmebalanse og fordelaktige sulfateringsforhold. According to the present invention, a method for sulphating non-ferrous metals, e.g. Cu, Co, Ni and Zn, which are present in small quantities in finely divided sulphide ores or concentrates, in a fluidized bed furnace under fine regulation of the temperature by injecting water directly into the fluidized bed, characterized by the fact that the oxidic material, which has been roasted from the sulphide ore, is added unroasted sulphide ore in an amount of 0.05 - 1 times the amount of oxidic material to provide heat balance and beneficial sulphation conditions.
I denne fremgangsmåten utgår man fra det prinsipp at til sulfateringen anvendes bare så mye sulfidmalmer, som er nodvendig for å tilveiebringe varmelikevekt og hensiktsmessige sulfateringsforhold. Den tilforte sulfidmalmens minstemengde avhenger av hvordan den nodvendige temperatur kan oppnåes og opprettholdes. På den annen side må mengden av sulfidmalm være tilstrekkelig for at man i ovnen skal kunne oppnå en gassblanding i hvilken mengden av SO^ er tilstrekkelig for dannelse av metallsulfater. Bare en brokdel sulfidmalmer er nodvendig i totalinnmatningen. Malmene kan enten tilfores torre eller fuktige som i naturlig tilstand. In this method, the principle is that only as much sulphide ore is used for the sulphation as is necessary to provide thermal equilibrium and appropriate sulphation conditions. The minimum amount of sulphide ore added depends on how the required temperature can be achieved and maintained. On the other hand, the amount of sulphide ore must be sufficient so that a gas mixture can be obtained in the furnace in which the amount of SO^ is sufficient for the formation of metal sulphates. Only a fraction of sulphide ores is required in the total input. The ores can either be supplied dry or moist as in their natural state.
Ved undersøkelse av de reaksjonshastigheter i hvirvelsjiktet som er aktuelle ved den sulfaterende rosting, er det konstatert at reaksjonene 1, 2 og 3 er svært hurtige, og av denne grunn må det i forhold til ovnstorrelsen være flere tilforingssteder for sulfidmalm for tilveiebringelse av en tilstrekkelig jevn SOg-atmosfære i hvirvelsjiktet, derimot trenges det for oksydmalms vedkommende vanligvis ikke mer enn et tilforingssted. Da de fordelaktige betingelser, forst og fremst for gass-sammensetningen, som skal til for en heldig gjennom-foring av sulfateringen, vanligvis kan reguleres ved at det holdes et forhold mellom sulfidmalm og oksydmalm innen videre grenser, gjenstår opprettholdelsen av varmelikevekten som er en begrensende faktor. Tilfdringsforholdet må derfor velges således at den sluttlige finregu-leringen av temperaturen skjer ved hjelp av en liten direkte vanninnsproytning i hvirvelsjiktet. Dette forårsaker ikke noen vesentlig avkjoling av avlopsgassene. When examining the reaction rates in the fluidized bed that are relevant in sulphating roasting, it has been established that reactions 1, 2 and 3 are very fast, and for this reason, in relation to the size of the furnace, there must be several supply points for sulphide ore to provide a sufficiently uniform SOg atmosphere in the vortex layer, on the other hand, in the case of oxide ore, usually no more than a supply point is needed. As the favorable conditions, primarily for the gas composition, which are required for a successful completion of the sulphation, can usually be regulated by maintaining a ratio between sulphide ore and oxide ore within further limits, the maintenance of the thermal equilibrium remains, which is a limiting factor. The supply ratio must therefore be chosen in such a way that the final fine-regulation of the temperature takes place by means of a small direct injection of water into the fluidized bed. This does not cause any significant cooling of the waste gases.
Ved denne fremgangsmåten oppnåes en flerdobbelt kapasitet med hensyn til ovnsenhet sammenlignet med tidligere fremgangsmåter, hvor det som utgangsstoffer bare ble anvendt sulfidmalmer. På grunn av at man ved hjelp av fremgangsmåten ifolge foreliggende oppfinnelse på en fordelaktig måte kan sulfatere oksydmalmer, folger det av dette at hoveddelen av sulfidmalmene forst på vanlig måte kan rostes til oksydmalmer, hvorved betydelig bedre SC^-gasser kan gjenvinnes enn ved på tidligere måte å sulfatere sulfidmalmer direkte, og hvorved det dessuten oppnåes en fordelaktig varmeokonomi. With this method, a multifold capacity is achieved in terms of furnace unit compared to previous methods, where only sulphide ores were used as starting materials. Due to the fact that by means of the method according to the present invention oxide ores can be sulphated in an advantageous way, it follows from this that the main part of the sulphide ores can first be roasted into oxide ores in the usual way, whereby significantly better SC^ gases can be recovered than in the past way of sulphating sulphide ores directly, and whereby an advantageous heat economy is also achieved.

Sulfidmalmanalyse: Sulfide Ore Analysis:
Produktet fra denne sulfidmalm rostet i en fluidiserende rosteovn ga analysen: The product from this sulphide ore roasted in a fluidizing roasting furnace gave the analysis:
Ved sulfateringstemperaturen 670°G må gassens hastighet i forhold til ovnens frie tverrsnittsoverflate beregnes til 0.25 m/s. Tilforingsmengdene var ved forskjellige betingelser folgende: At the sulphation temperature of 670°G, the velocity of the gas in relation to the free cross-sectional surface of the furnace must be calculated as 0.25 m/s. The supply quantities were, under different conditions, as follows:
SR = svovelkismalm SR = sulphide ore
PJ = rostet produkt fra svovelkismalmen PJ = roasted product from the sulphide ore
Med totaltilforselsforholdet' 1:6 oppnår man således en 5~ dobbelt kapasitet sammenlignet med ren svovelmalmtilforsel. With the total supply ratio of 1:6, a 5~ double capacity is thus achieved compared to pure sulfur ore supply.

Ni = 0.11 - 0.12$ Nine = 0.11 - 0.12$
Cu = 0.02 - 0.03$ Cu = 0.02 - 0.03$
Zn = 0.12 - 0.13 $ Zn = 0.12 - 0.13 $
Sulfid S = 0.2 % Sulfide S = 0.2%
Hvirvelsjiktets temperatur var 670°-675°C. Malmen ble til-fort ved en fuktighet på 6-7 $. The fluid bed temperature was 670°-675°C. The ore was added at a moisture content of 6-7 $.
Avlopsgassenes S0g + S0^ var ca. 7-9$ °g i overensstemmelse med dette var oksygeninnholdet ca. 8$ (av torrgassen). The waste gas's S0g + S0^ was approx. 7-9$ °g in accordance with this, the oxygen content was approx. 8$ (of the dry gas).
