Föreliggande uppfinning avser således ett sätt att genom skumflotation separera kiselhaltiga föreningar från oxidiska mineral. Flotationen utföres i närvaro av en sam- lare, som innefattar en kombination av a) en eterdiamin med den allmänna formeln R - 0 - (cnflzncnx - (cH2)y - NH - (cH2)Z - :m2 eller ett salt av denna, där R betecknar en rak eller grenad alífatisk kolväterest med minst 6 kolatomer, n är ett tal mellan l och 3, x ett tal mellan O och Ä, y ett tal mellan 2 pch 6 och z ett tal mellan 2 och 10, och en fettamin med den allmänna formeln nl - [NH-(cnnznflp - NHQ, eller ett salt av denna, där Rl betecknar en rak eller grcnad alifatisk kol- väterest med minst 8 kolatomer, n är ett tal mellan 2 och 10 och p ett tal mellan 0 och 3, varvid viktför- hâllandet eterdiamin till fettamin överstiger l,l:l.The present invention thus relates to a method of by foam flotation separate siliceous compounds from oxidic minerals. The flotation is carried out in the presence of a which comprises a combination of a) an ether diamine of the general formula R - 0 - (cn fl zncnx - (cH2) y - NH - (cH2) Z -: m2 or a salt thereof, wherein R represents a straight or branched aliphatic hydrocarbon radical having at least 6 carbon atoms, n is a number between l and 3, x a number between 0 and Ä, y a number between 2 pch 6 and z a number between 2 and 10, and a fatty amine of the general formula nl - [NH- (cnnzn fl p - NHQ, or a salt thereof, where R1 represents a straight or green aliphatic carbon hydrogen residue with at least 8 carbon atoms, n is a number between 2 and 10 and p a number between 0 and 3, the weight ratio the ratio of ether diamine to fatty amine exceeds 1,1: 1.
I eterdiaminerna betecknar R lämpligen en kolväte- rest med 8 till 2U kolatomer och företrädesvis en sådan rest med 8 till lü kolatomer. x är lämpligen 0 eller l, företrädesvis 0. y är lämpligen 2 till N och z lämpligen 3 till 5. n är företrädesvis 2 eller 3. Som exempel på lämpliga eterdiaminer kan nämnas följande: N-(3-oktoxy- propyl)-propylendiamin, N-(3-dekoxypropyl)-propylendia- min, N-(3-dodekoxyisopropyl)-propylendiamin, N-(2-oktoxy- etyl)-etylendiamin och N-(2-dekoxyetyl)-etylendiamint I samtliga fall kan givetvis den längre alifatiska resten vara grenad, så kan exempelvis oktyl-gruppen utgöras av en 2-etylhexylgrupp.In the ether diamines, R suitably represents a hydrocarbon residue having 8 to 2U carbon atoms and preferably one traveled with 8 to lü carbon atoms. x is suitably 0 or 1, preferably 0. y is suitably 2 to N and z is suitably 3 to 5. n is preferably 2 or 3. As an example suitable ether diamines include the following: N- (3-octoxy- propyl) -propylenediamine, N- (3-decoxypropyl) -propylenediamine- min, N- (3-dodecoxyisopropyl) -propylenediamine, N- (2-octoxy- ethyl) -ethylenediamine and N- (2-decoxyethyl) -ethylenediamine In all cases, of course, the longer aliphatic residue be branched, for example, the octyl group may be a 2-ethylhexyl group.
.Fettaminerna innehåller en rak eller grenad ali- fatisk kolväterest med minst 8 kolatomer och antalet bör ej överstiga 2ü. Lämpligen innefattar gruppen 10 till 16 kolatomer. n är företrädesvis 2 till 6. Som exempel på lämpliga fettaminer kan nämnas: oktyl-1,3-propylendiamin, dodecyl-l,2-etylendiamin, dodecyl-1,3-propylendiamin, oktylamin, decylamin, dodecylamin, tetradecylamin. Fett- diaminerna är speciellt föredragna. b) 15' 20. 25. 30. 55- 8005156-8 3 De alifatiska kolväteresterna i såväl eterdiaminen som fettaminen kan givetvis innehålla omättnader och utgö- ras exempelvis av oleín- eller linoleingrupper. Resterna kan även utgöras av blandningar av naturligt förekommande alkyl- och/eller alkenylgrupper. Såväl fettaminerna som eterdiaminerna kan användas i fri form eller i form av salt av mineralsyra eller organisk syra. Om aminerna an- vändes i saltform, föredrages av ekonomiska skäl acetater och hydroklorider.The fatty amines contain a straight or branched ali- phatic hydrocarbon residue having at least 8 carbon atoms and the number should not exceed 2ü. Suitably the group comprises 10 to 16 carbon atoms. n is preferably 2 to 6. As an example suitable fatty amines may be mentioned: octyl-1,3-propylenediamine, dodecyl-1,2-ethylenediamine, dodecyl-1,3-propylenediamine, octylamine, decylamine, dodecylamine, tetradecylamine. Fat- the diamines are especially preferred. b) 15 ' 20. 25. 30. 55- 8005156-8 3 The aliphatic hydrocarbon residues in both the ether diamine which the fatty amine may of course contain unsaturations and for example by olein or linolein groups. The remains can also consist of mixtures of naturally occurring alkyl and / or alkenyl groups. Both the fatty amines and the ether diamines can be used in free form or in the form of salt of mineral acid or organic acid. If the amines are used turned into salt form, acetates are preferred for economic reasons and hydrochlorides.
För erhållande av bästa separationseffekt bör det föreligga ett viktmässigt överskott av eterdíaminen i kom- binationen och viktförñållandet eterdiamin till fettamin överstiger 1,1 till 1. Företrädesvis ligger viktförhållan- det inom intervallet l,5:l till 3:1.In order to obtain the best separation effect, it should there is an excess by weight of the ether diamine in the the combination and weight ratio of ether diamine to fatty amine exceeds 1.1 to 1. Preferably, the weight ratio is it in the range 1.5: 1 to 3: 1.
Den angivna kombinationen av fettaminer och eter- diaminer kan utnyttjas som samlare i olika mineralsystem, där separation av kiselhaltiga föreningar såsom kvarts, fältspat,alkalimetallsilikater och andra silikater önskas.The stated combination of fatty amines and ether diamines can be used as collectors in various mineral systems, where separation of silicon-containing compounds such as quartz, feldspar, alkali metal silicates and other silicates are desired.
De kan utnyttjas vid rening av olika kalciummineral och järnmineral såsom magnetit, hematit, takonit och ítaberit.They can be used in the purification of various calcium minerals and iron minerals such as magnetite, hematite, taconite and itaberite.
Speciellt lämplig är användningen av kombinationerna vid rening av järnmineral och de ger härvid mycket god effekt och erhållna mineralkoncentrat tillfredsställer de krav på låga silikat- och alkalihalter, som ställs från den stålproducerande industrins sida. Den vid flotation an- vända totala mängden av eterdiamin och fettamin beror gi- vetvis av typ av mineral, önskad separationseffekt etc.The use of the combinations is particularly suitable purification of iron minerals and they give a very good effect and obtained mineral concentrates meet the requirements on low silicate and alkali contents, set from it side of the steel manufacturing industry. The flotation used the total amount of ether diamine and fatty amine know of type of mineral, desired separation effect etc.
Vanligen utnyttjas mängder överstigande 20 g per ton torrt mineralgods och oftast ligger mängden inom intervallet HO till 200 g/ton.Amounts in excess of 20 g per tonne of dry matter are usually used mineral goods and usually the amount is within the range HO to 200 g / ton.
Med en kombination av eterdiamin och fettamin enligt uppfinningen erhålles väsentligt bättre effekt, än om motsvarande mängd av enbart eterdiamin eller enbart fettamin användes. Aminblandningen medger en väsentlig sänkning av föroreningshalterna utan att därigenom ge upp- hov till minskade utbyten. Med användning av överskott av eterdiaminer i blandningarna erhålles en produkt, som i sig är flytande och dispergerbar direkt i pulpen, utan att aminerna dessförinnan behövt underkastas saltbildning. ' _sccs1se-a 10. 15. 20. 25. 50. 55.With a combination of ether diamine and fatty amine according to the invention a significantly better effect is obtained, than if the corresponding amount of ether diamine alone or alone fatty amine was used. The amine mixture allows a substantial reduction of pollution levels without thereby giving up hoof to reduced yields. Using excess of ether diamines in the mixtures a product is obtained which in itself is liquid and dispersible directly in the pulp, without that the amines had previously had to be subjected to salt formation. ' _sccs1se-a 10. 15. 20. 25. 50. 55.
M Aminblandningen fördelar sig lätt i pulpen och även för i omrörningshänseende tunga system erfordras endast korta konditioneringstider. Kombinationerna av aminer enligt uppfinningen kan givetvis även tillsättas systemen i form av lösning eller dispersion i vatten eller annat lösnings- medel, om så önskas.M The amine mixture is easily distributed in the pulp and also in stirring heavy systems are required only short conditioning times. The combinations of amines according to the invention can of course also be added to the systems in form of solution or dispersion in water or other solution funds, if desired.
Effekten av samlarkombinationen enligt uppfinningen är i huvudsak oberoende av pulptäthet, pulpens pH och tem- peratur. Det bör speciellt nämnas, att kombinationerna är mycket effektiva vid låga temperaturer, ned mot OOC, och att de ej är speciellt känsliga för vattnets kvalitet. De kan utnyttjas i system med vatten av mycket varierande hårdhetsgrad och likaså i system, vilka i stor utsträck- ning utnyttjar havsvatten. Samlarkombinationen kan givet- vis användas í kombination med gängse andra flotations- kemikalier såsom dispergeringsmedel, aktivatorer, skum- bildare, tryckarreagenser etc.The effect of the collector combination according to the invention is essentially independent of pulp density, pulp pH and temperature. peratur. It should be especially mentioned that the combinations are very effective at low temperatures, down to OOC, and that they are not particularly sensitive to the quality of the water. The can be used in systems with water of very varying hardness and also in systems, which to a large extent uses seawater. The collector combination can be given be used in combination with other common flotation chemicals such as dispersants, activators, foams formers, pressure reagents, etc.
Uppfinníngen avser även ett medel för användning som samlare vid separation av kiselhaltiga gångarter från oxidiska mineral medelst skumflotation, vilket medel inne- fattar en kombination av en eterdíamin, eller salt därav, och en fettamin, eller salt därav, såsom tidigare defini- erade, varvid viktförhållandet eterdiamin till fettamin överstiger l,l:l. Speciellt föredragna medel innefattar de angivna eterdiaminerna i kombination med fettdíamin.The invention also relates to a means for use as a collector in the separation of siliceous gaits from oxidic minerals by foam flotation, which means takes a combination of an ether diamine, or salt thereof, and a fatty amine, or salt thereof, as previously defined the weight ratio of ether diamine to fatty amine exceeds l, l: l. Particularly preferred agents include the specified ether diamines in combination with fatty diamine.
Lämpligen innehåller medlen en kombination av eterdiamin och fettamin med ett viktförhållande inom intervallet 1,5:l till 2:1.Suitably the compositions contain a combination of ether diamine and fatty amines with a weight ratio within the range 1.5: 1 to 2: 1.
