Description
Oppfinnelsen angår en fremgangsmåte til anrikning av metallsulfidmalmer. Denne fremgangsmåte angår'spesielt en sådan prosess hvor skumfIotasjon anvendes i kombinasjon med The invention relates to a method for the enrichment of metal sulphide ores. This method particularly concerns such a process where foam flotation is used in combination with
en metallsamler innbefattende et N-all.yl-O— alkyltionokarbamat. a metal collector including an N-allyl-O-alkylthionocarbamate.
Mange betydningsfulle metaller forekommer i naturen i f orm av sulf idmalmer.. Slike malmer opptrer ..på forskjellige Many important metals occur in nature in the form of sulphide ores.. Such ores appear ..in different
'steder i verden, og på mange steder er malmforekomstene av tilstrekkelig størrelse for'utvinning ved gruvebrytnings-operasjoner, hvoretter forskjellige metoder- anvendes for ut-vinning av metallinnholdet.. places in the world, and in many places the ore deposits are of sufficient size for extraction by mining operations, after which different methods are used to extract the metal content.
Skumflotasjon er den viktigste metode for konsentrering eller anrikning av en rekke verdifulle malmmineraler. Den vesentligste fordel er at den er en forholdsvis effektiv ope-rasjon med vesentlig lavere kostnad enn mange andre prosesser. Foam flotation is the most important method for concentrating or beneficiating a number of valuable ore minerals. The most significant advantage is that it is a relatively efficient operation with significantly lower costs than many other processes.
Flotasjon er en prosess for- separering av finmalte verdifulle mineraler fra med disse forenet gangart eller avfall, eller.for separering av verdifulle komponenter fra hverandre. Flotation is a process for the separation of finely ground valuable minerals from gangue or waste combined with these, or for the separation of valuable components from each other.
Ved skumflotasjon tilveiebringes skumdannelse ved .innføringIn foam flotation, foam formation is provided by introduction
av luft i en pulp eller oppslemning. av findelt malm og vann of air in a pulp or slurry. of finely divided ore and water
inneholdende et skumdannelsesrniddel. Mineraler som har en • spesiell affinitet til luftbobler, 'stiger til overflaten i containing a foaming agent. Minerals which have a • special affinity for air bubbles, 'rise to the surface i
skummet og separeres fra dem som fuktes av. vannet. De partikler som skal separeres ved skumflotasjon, må ha en slik.. skimmed and separated from those that are wetted off. the water. The particles to be separated by foam flotation must have such a..
størrelse at de lett kan løftes av luftboblene. size that they can be easily lifted by the air bubbles.
Midler som kalles samlere anvendes i kombinasjon méd Agents called collectors are used in combination with
.flotasjon for å lette utvinningen av det ønskede mineral..flotation to facilitate the extraction of the desired mineral.
De valgte midler må selektivt kunne belegge det ønskede mine-.ral til tross for tilstedeværelse av mange andre mineralslag.; The agents chosen must be able to selectively coat the desired mineral despite the presence of many other mineral types.
Den rådende' teori angir at fIotasjonsseparasjon av ett mine-.ralslag f ra- et annet beror .på den relative fuktbarhet' av overflatene. Typisk senkes den frie overflateenergi. bety-delig gjennom adsorps jon av heteropolære overflateaktive midler. Det hydrofobe belegg som tilveiebringes på denne måte-, virker i henhold til denne forklaring som en bro,, slik at partiklene kan festes til en luftboble. Fremgangsmåten ifølge- oppfinnelsen er ikke begrenset til denne eller andre teorier for flotasjon. The prevailing theory states that flotation separation of one mineral layer from another depends on the relative wettability of the surfaces. Typically, the surface free energy is lowered. significantly through adsorption of heteropolar surfactants. The hydrophobic coating thus provided acts according to this explanation as a bridge, so that the particles can be attached to an air bubble. The method according to the invention is not limited to this or other theories of flotation.
Mange métallsulfidmalmer anrikes ved skumflotasjon under anvendelse av. en rekke forskjellige samlere. Slike sulfid- malmer innbefatter eksempelvis svovelkis (FeS2), kobberkis Many metal sulphide ores are beneficiated by foam flotation using a number of different collectors. Such sulphide ores include, for example, sulfur pyrite (FeS2), copper pyrite
(CuFeS2) , kobberglans (Cu2S) , blyglans (PbS) , sinkblende- (ZnS) , (CuFeS2), copper luster (Cu2S), lead luster (PbS), zinc blende (ZnS),
molybdenitt (MoS'2) , sinober (HgS) , kovellitt (CuS), bornitt (Cu^FeS^) og lignende, såvel som blandmalmer. molybdenite (MoS'2), cinnabar (HgS), covellite (CuS), bornite (Cu^FeS^) and the like, as well as mixed ores.
Selv om disse og andre malmer effektivt kan behandlesAlthough these and other ores can be effectively processed
for fremstilling av konsentrater med øket metallinnhold, foreligger det.likevel behov for mer■effektive samlere som gir øket utbytte av metallinnholdet under bibeholdelse av høy-gradig utbytte. I betraktning av de store mengder metallsulfider som behandles ved skumflotasjon,' kan én sådan ut-vikling medføre en vesentlig økning av den samlede mengde ' metallbestanddeler som utvinnes og gi vesentlige økonomiske fordeler, endog om .en moderat økning av utbyttet oppnås. Til-veiebringelsen av en forbedret fremgangsmåte for skumflotasjon av metallsulfider skulle oppfylle et lenge følt behov og utgjøre et vesentlig fremskritt på området. for the production of concentrates with an increased metal content, there is nevertheless a need for more efficient collectors which give an increased yield of the metal content while maintaining a high yield. Considering the large quantities of metal sulphides that are treated by foam flotation, one such development can lead to a significant increase in the total amount of metal constituents that are extracted and provide significant economic benefits, even if a moderate increase in the yield is achieved. The provision of an improved method for foam flotation of metal sulphides should fulfill a long-felt need and constitute a significant advance in the field.
I henhold til den foreliggende oppfinnelse tilveiebringes en fremgangsmåte for anrikning av en metallsulfidmalm, hvilken innbefatter maling av malmen, slik at man frem-bringer partikler'av flptérbar størrelse, oppslemning av partiklene i ét vannmedium, kondisjonering av oppslemningen According to the present invention, a method for beneficiation of a metal sulphide ore is provided, which includes grinding the ore so as to produce particles of filterable size, slurrying the particles in a water medium, conditioning the slurry
. med effektive mengder ,av skumdannelsesrniddel og metallsamler omfattende en forbindelse med strukturen . with effective amounts of foaming agent and metal aggregates comprising a connection with the structure
■ hvor .R er en alkylgruppe. med 1-6 karbonatomer, og flotéring av deønskede verdifulle malmbestanddeler ved skumflotasjon. ■ where .R is an alkyl group. with 1-6 carbon atoms, and flotation of the desired valuable ore constituents by foam flotation.
Helt overraskende gir fremgangsmåten ifølge oppfinnelsen Quite surprisingly, the method according to the invention gives
'metarikonsentråter med forbedret, konsentrasjon og forbedret utbytte sammenlignet med hva som erholdes når prosessen utfø-res under anvendelse av nær beslektede, tidligere kjente samlere. Den forbedrede konsentrasjon og det forbedrede utbytte leder til'at man oppnår større mengde av verdifullt metall ved hjelp av fremgangsmåten ifølge.oppfinnelsen og gir herigjennom vesentlige økonomiske fordeler. 'metariconcentrates with improved concentration and improved yield compared to what is obtained when the process is carried out using closely related, previously known collectors. The improved concentration and the improved yield lead to a greater amount of valuable metal being obtained by means of the method according to the invention and thereby provide significant economic advantages.
Ved utførelse av fremgangsmåten ifølge oppfinnelsen males en metallsulfidmalm som skal behandles, ..slik at man erholder partikler av flotér.bar størrelse'. I alminnelighet er det malte materiales partikkelstørrelse slik at størstedelen av partiklene er mindre enn 200 mesh (U.S. screen, 0,74 mm). When carrying out the method according to the invention, a metal sulphide ore to be treated is ground, ..so that particles of a floatable size are obtained'. In general, the particle size of the ground material is such that the majority of the particles are smaller than 200 mesh (U.S. screen, 0.74 mm).
Den malte malm beredes som en vannoppslemning inneholdende fra ca. 50 til 75 vekt% malt malm,, basert på,den samlede oppslemningsvekt, fortrinnsvis ca. 65-70 vékt% på samme basis. Den på denne måte .erholdte oppslemning kondisjoneres med skumdannelsesrniddel og samlerreagens i effektive mengder. Brenselolje.og andre skumnédtrykkere kan også anvendes'. f or regulering av skumdannelsen om så:ønskes. The ground ore is prepared as a water slurry containing from approx. 50 to 75% by weight ground ore, based on the total slurry weight, preferably approx. 65-70% by weight on the same basis. The slurry obtained in this way is conditioned with foaming agent and collecting reagent in effective quantities. Fuel oil and other foam suppressants can also be used'. for regulation of foam formation if desired.
Dén kondisjonerte oppslemning underkastes deretter kon-vensjonell skumflotasjon, og metallinnholdet utvinnes med skummet. F.lotasjbnen kan utføres i ett eller flere trinn om så. ønskes', med tilsats av mer skumdannelsesrniddel i etter-følgende, trinn om så ønskes. The conditioned slurry is then subjected to conventional foam flotation, and the metal content is recovered with the foam. The F.lotsjbn can be carried out in one or more steps if so. desired', with the addition of more foaming agent in subsequent steps if desired.
Samlerforbindelsene ifølge.foreliggende oppfinnelse har den generelle struktur The collector connections according to the present invention have the general structure
hvor R er en alkylgruppe med 1-6 karbonatomer. Forbindelser med denne struktur inkluderer N-al,lyl-0-metylti.onokarbamat, N-ailyl-O-etyltionokarbamat, N.^allyl-O-isopropyltionokarbamat, N-allyl-O-n-propyltionokarbamat, N-allyl-O-isobutyltiono-karbamat og N-allyl-0-n-amyit.ionokarbamat og lignende. where R is an alkyl group with 1-6 carbon atoms. Compounds with this structure include N-allyl-O-methylthionocarbamate, N-allyl-O-ethylthionocarbamate, N-allyl-O-isopropylthionocarbamate, N-allyl-O-n-propylthionocarbamate, N-allyl-O-isobutylthionocarbamate carbamate and N-allyl-O-n-amylite.ionocarbamate and the like.
Samlerforbindelsen anvendes■ved fremgangsmåten ifølge, oppfinnelsen i. en effektiv mengde. Med. "en effektiv, mengde" menes en mengde som gir en ønsket grad av anrikning av den ønskede metallbestanddel. Den spesifikke mengde av. samler, som anvendes med ulike metallsulfidmalmer, kan variere i høy grad. I alminnelighet er det effektive samleranvendelsesnivå en verdi pa ca. 0 , 0004.5 . til ca . 0 , 045 kg,' fortrinnsvis 0, 0027 til'0,027 kg samler pr. tonn malm. The collector compound is used in the method according to the invention in an effective amount. With. "an effective amount" means an amount which gives a desired degree of enrichment of the desired metal component. The specific amount of. collectors, which are used with different metal sulphide ores, can vary greatly. In general, the effective collector usage level is a value of approx. 0 , 0004.5 . to approx. 0.045 kg, preferably 0.0027 to 0.027 kg collector per tons of ore.
Også skumdannelsesmidlet anvendes i effektive mengder som ved konvensjonelle metoder. I alminnelighet anvendes skumdannelsesrniddel 1 en mengde på ca. 0,0045 til 0,045 kg pr. tonn- malm. Egnede skumdannelsesmidler er velkjente for fag-mannen og inkluderer eksempelvis me.tylisobutylkarbinol, 6- til • 8-karbon-alkoholer og. lignende. The foaming agent is also used in effective amounts as in conventional methods. In general, foaming agent 1 is used in an amount of approx. 0.0045 to 0.045 kg per tonnes of ore. Suitable foaming agents are well known to those skilled in the art and include, for example, methylisobutylcarbinol, 6- to • 8-carbon alcohols and. the like.
Ved fremgangsmåten ifølge oppfinnelsen kan man som metallsamler anvende visse kombinasjoner av N-allyl-0-alkyl'tiono-. In the method according to the invention, certain combinations of N-allyl-O-alkyl'thiono- can be used as metal collectors.
karbamater og andre forbindelser, forutsatt.at disse kombinasjoner ikke forringer anvendelsesegenskapene hos de angitte tioriokarbamaterSom eksempel har kombinasjoner av et alkalimetall- eller ammoniumsalt av et dialkylditiofosfat med for-•. melen carbamates and other compounds, provided that these combinations do not impair the application properties of the stated thioriocarbamates. For example, combinations of an alkali metal or ammonium salt of a dialkyldithiophosphate with for-•. the flour

Arbeidsmåten ifølge Eksempel. 1 ble anvendt med unntagelse av at.den anvendte samler var N-isopropyl-G-etylkarba-mat, en tidligere kjent samler. Resultatene angis også i Tabell I. . Resultatene i'Tabell I viser at fremgangsmåten ifølge oppfinnelsen gir høyere kobber-utbytter enn den tidligere, kjente prosess under bibeholdelse av høye konsentrasjoner. The way of working according to Example. 1 was used with the exception that the collector used was N-isopropyl-G-ethylcarbamate, a previously known collector. The results are also given in Table I. . The results in Table I show that the method according to the invention gives higher copper yields than the previously known process while maintaining high concentrations.
Eksempel 2Example 2
Den generelle arbeidsmåte ble på ny fulgt med unntagelse av at en serie N-allyl-O-alkyltionokarbamater ble vurdert hver for seg eller i visse kombinasjoner med hatriumdiisobutyl-. ditiofosfat..Siden alle ditiortokarbamatene oppviser innbyrdes forskjellig oppløseli.ghet i ditiofosfatreagenset, ble utprøv-ningen av blandingene utført ved forskjellige innhold.av bestanddelene. Resultatene angis i Tabell II. The general procedure was again followed with the exception that a series of N-allyl-O-alkylthionocarbamates were evaluated individually or in certain combinations with sodium diisobutyl-. dithiophosphate. Since all the dithioorthocarbamates show mutually different solubility in the dithiophosphate reagent, the tests of the mixtures were carried out at different contents of the components. The results are shown in Table II.
Resultatene i Tabell II viser at N-allyl-O-alkyltionokarbamater i alminnelighet ved anvendelse alene gir økninger av utbyttet med økende alkylkjédelengde. Resultatene viser også at økede utbytteverdier erholdes med blandinger av N-allyl-O-ålkyltionokarbamater og dialkylditiofosfatsalt, når metyl-, etyl- og n-propylderivater av tionokarbamatene anvendes. Andre alkylåilyltionokarbamater' i kombinasjon med dialkylditiofosfatsalt gir høyere utbytte enn de lavere alkyl-allyltionokarbamater ved anvendelse alene. The results in Table II show that N-allyl-O-alkylthiocarbamates generally, when used alone, give increases in yield with increasing alkyl chain length. The results also show that increased yield values are obtained with mixtures of N-allyl-O-alkylthiocarbamates and dialkyldithiophosphate salt, when methyl, ethyl and n-propyl derivatives of the thionocarbamates are used. Other alkylallylthiocarbamates' in combination with dialkyldithiophosphate salt give higher yields than the lower alkylallylthiocarbamates when used alone.
