Även andra anjoniska samlare som alkylbensensulfonat, alkylfosfat, alkylsulfat och alkylsulfosuccinamat har föreslagits som samlare för apatit men de har icke tillfredsställande löst separa- tionsproblemet. _ Enligt föreliggande uppfinning har det nu visat sig möjligt att med gott resultat skumflotera kalciumfosfathaltiga mineral, så- som apatit och fosforiter under användning av en amfotär ytaktiv fö- rening. Denna amfotära ytaktiva förening kan åskâdliggöras med den allmänna formeln .

Other anionic collectors such as alkylbenzene sulfonate, alkyl phosphate, alkyl sulfate and alkyl sulfosuccinamate have also been proposed as collectors for apatite but have not satisfactorily solved the separation problem. According to the present invention, it has now been found possible with good results to foam flotate calcium phosphate-containing minerals, such as apatite and phosphorites, using an amphoteric surfactant. This amphoteric surfactant compound can be illustrated by the general formula. R1 R - (_ou) n -I (mp - C212 - cmoa) -g C112 - E - cqnzqv 7 'l24. A ïïïïä fi for example 10 - 18 carbon atoms, each A represents an oxyalkylene group having 2 to 4 carbon atoms, R 10 is one where R is a hydrocarbon group of ïalkyl group of 1 - 4 carbon atoms or hydrogen, Y is the group C00 or g l, p_ is a number from 0 - 5 and q is l el1er'2, el. salts thereof.
Föredragna föreningar enligt uppfinningen är de, där n och q' är 1 och Rl är en metylgrupp. Speciellt föredragna är föreningar, där dessutom R är en alkylfenylgrupp, och Y betecknar gruppen C00. De fö- 'redragna föreningarna kan lätt framställas i höga utbyten under an- vändning av kommersiellt lättillgängliga och billiga utgångsproduk- ter samtidigt som de uppvisar mycket tillfredsställande flotations- egenskaper. _ Samlarreagensets hydrofila och hydrofoba del kan på i och för sig känt sätt varieras för att erhålla en lämplig hydrofil-lipofil- balans som anpassats efter den malm, som skall floteras. Vid lämpliga ' utföringsformer inom uppfinningens ram kan man t ex utan svårighet ur en malm, som endast innehåller 10 % apatit och 35 % kalcit och en lrest av silikatmineral, efter endast tre repeteringar erhålla ett koncentrat med ca 80 % apatit i ett 85-procentigt utbyte.Preferred compounds of the invention are those wherein n and q 'are 1 and R 1 is a methyl group. Particularly preferred are compounds wherein in addition R is an alkylphenyl group, and Y represents the group C00. The preferred compounds can be readily prepared in high yields using commercially available and inexpensive starting materials while exhibiting very satisfactory flotation properties. The hydrophilic and hydrophobic part of the collector reagent can be varied in a manner known per se to obtain a suitable hydrophilic-lipophilic balance adapted to the ore to be floated. In suitable embodiments within the scope of the invention, for example, a concentrate with about 80% apatite can be obtained without difficulty from an ore which contains only 10% apatite and 35% calcite and a residue of silicate mineral. exchange.
Föreningarna enligt uppfinningen kan framställas under använd- ning av välkända reaktioner. I En metod är att epoxidera en C10-C27-CK-olefin och därefter omsätta den bildade epoxiden med en förening med den allmänna formeln R H ål C H Y _ A q^2q ' .F _¿.__.--... 3 a 78-02427-0 där RI, Y och q har den ovan angivna betydelsen. Epoxideringen kan ütföfas med en organisk peroxid, t ex tertiär butylhydroperoxid eller fiefåttiksyra, vid rumstemperatur eller förhöjd temperatur. Reaktionen mellan epoxiden och föreningen A utföres vid ett neutralt eller lätt bäsiskt pH, företrädesvis mellan 7 och 10, i närvaro av ett polärt lösningsmedel. Reaktionstemperaturen ligger lämpligen inom interval- let 50 - 14006 och reaktionstiden är från ca 15 minuter till ca 3 tinnar . .Én annan metod att framställa föreningarna enligt uppfinning- en år ätt omsätta en eventuellt oxialkylerad hydroxylförening med epiklorhydrin och därefter bringa den bildade klorglyceryletern att reagera med en förening enligt A. Om så önskas kan reaktionen med fö- reningen A utbytas mot ett tvâstegsförfarande, vilket omfattar en första reaktion med ammoniak eller en primär amin med formeln -Ih c H - N - H B där RI har den ovan angivna betydelsen och en andra reaktion med en förening med den allmänna formeln ' ClCqH2qY, C där Y och q har den ovan angivna betydelsen.The compounds of the invention may be prepared using well known reactions. One method is to epoxidize a C10-C27-CK-olefin and then react the formed epoxide with a compound of the general formula RH a1 CHY _ A q ^ 2q '.F _¿ .__. - ... 3 a 78-02427-0 where RI, Y and q have the meaning given above. The epoxidation can be carried out with an organic peroxide, for example tertiary butyl hydroperoxide or acetic acid, at room temperature or elevated temperature. The reaction between the epoxide and the compound A is carried out at a neutral or slightly alkaline pH, preferably between 7 and 10, in the presence of a polar solvent. The reaction temperature is suitably in the range of 50 - 14006 and the reaction time is from about 15 minutes to about 3 hours. Another method of preparing the compounds of the invention is to react an optionally oxyalkylated hydroxyl compound with epichlorohydrin and then react the chloroglyceryl ether formed with a compound of A. If desired, the reaction of compound A can be exchanged for a two step process, which comprises a first reaction with ammonia or a primary amine of the formula -Ih c H - N - HB where R 1 has the meaning given above and a second reaction with a compound of the general formula 'ClCqH2qY, C where Y and q have the above meaning.
Reaktíonen mellan hydroxylföreningen och epiklorhydrin ut- föres vid en temperatur av ca 100 - l50°C i närvaro av en katalysa- tor. Såsom katalysator har speciellt SnCl4, BF3 och HCl04 visat Siä utmärkta ooh de ger en snabb och lätt kontrollerbar reaktion, men även andra sura katalysatorer, såsom toluensulfonsyra och svavelsyra år ânvåndbara. För att erhålla fullständig omsättning av alkoholfö- reningen tillsättes epiklorhydrin vanligtvis i överskott. Amineringen av klorglyéeryletern med den primära aminen eller ammoniak utföres i närvaro av alkali, såsom natriumhydroxid, vid en temperatur av ca 100 ~ lšögê. Vanligtvis utföres reaktionen i närvaro av ett polärt lösningsmedel, t ex vatten eller lågmolekylär alkohol, såsom metanol, etanol, monoetylenglykol, dietylenglykol, etyldietylenglykol och etyletylenglykol. Den primära eller sekundära aminens reaktion med en förening med formeln C utföres i en neutraliserad vattenlösning, Várvid reaktionátemperaturen är 50 - l0O°C och reaktionstiden ca 2 - 6 timmar. innehåller aminen kolvätegrupper och mer än 14 kolatomer »fafe-e-w- w «.- - - -jzaozuzv-o - 4 'har det visat sig.fördelaktigt att även tillsätta en glykolförening, såsom etyldietylenglykol, dels för att öka aminens löslighet dels~ för att sänka reaktionsblandningens viskositet. Hydroxylföreningen enligt uppfinningen kan utgöras av alifatiska alkoholer med 7 - 24 kolatomer och de kan vara såväl syntetiska som härledda ur naturpro- dukter. De "naturligt" härledda, de s k fettalkoholerna, framställes 'vanligtvis genom reduktion av fettsyror eller fettsyreestrar erhåll- na från vegetabiliska oljor, kokosolja, palmolja, sojaolja, linolja, majsolja eller ricinolja, animaliska oljor eller fetter, såsom fisk- olja, valolja, talg eller ister. Som exempel på lämpliga alkoholer bör följande nämnas: decylalkohol, laurylalkohol, myristylalkohol, cetylalkohol, stearylalkohol, eikosylalkohol, oleylalkohol eller ei~ kocenylalkohol. Syntetiska alkoholer framställes företrädesvis en- ligt Zieglerförfarandet eller genom Oxo-processen. De flesta medelst Oxo-processen framställda alkoholerna har en mer eller mindre grenad kolkedja, varför i detta fall ett stort antal isomerer är möjliga.The reaction between the hydroxyl compound and epichlorohydrin is carried out at a temperature of about 100-150 ° C in the presence of a catalyst. As a catalyst, SnCl4, BF3 and HClO4 in particular have shown excellent properties and give a rapid and easily controllable reaction, but other acid catalysts such as toluenesulfonic acid and sulfuric acid are also unusable. To obtain complete conversion of the alcohol compound, epichlorohydrin is usually added in excess. The amination of the chloroglyceryl ether with the primary amine or ammonia is carried out in the presence of alkali, such as sodium hydroxide, at a temperature of about 100 ° C. Usually the reaction is carried out in the presence of a polar solvent, for example water or low molecular weight alcohol, such as methanol, ethanol, monoethylene glycol, diethylene glycol, ethyl diethylene glycol and ethyl ethylene glycol. The reaction of the primary or secondary amine with a compound of formula C is carried out in a neutralized aqueous solution, the reaction temperature being 50 DEG-10 DEG C. and the reaction time about 2 to 6 hours. the amine contains hydrocarbon groups and more than 14 carbon atoms »fafe-ew- w« .- - - -jzaozuzv-o - 4 ', it has been found advantageous to also add a glycol compound, such as ethyldiethylene glycol, partly to increase the solubility of the amine and to lower the viscosity of the reaction mixture. The hydroxyl compound according to the invention may consist of aliphatic alcohols having 7 to 24 carbon atoms and they may be both synthetic and derived from natural products. The "naturally" derived so-called fatty alcohols are usually prepared by reduction of fatty acids or fatty acid esters obtained from vegetable oils, coconut oil, palm oil, soybean oil, linseed oil, corn oil or castor oil, animal oils or fats such as fish oil, whale oil, tallow or lard. Examples of suitable alcohols are the following: decyl alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, eicosyl alcohol, oleyl alcohol or eicocenyl alcohol. Synthetic alcohols are preferably prepared according to the Ziegler process or by the Oxo process. Most alcohols produced by the Oxo process have a more or less branched carbon chain, so in this case a large number of isomers are possible.
Förutom alifatiska alkoholer kan även cykloalifatiska och framförallt aromatiska hydroxylföreningar utnyttjas som utgângspro- dukt. Lämpliga cykloalifatiska alkoholer är cyklohexanol, cyklohepta- nol, cyklooktanol, cyklododekanol och cyklohexadekanol. Av lämpliga aromatiska hydroxylföreningar bör framförallt framhållas syntetiskt framställda mono- och dialkylsubstituerade fenoler, sâsom-oktylfe- nol, nonylfenol, dodecylfenol, hexadecylfenol, dibutylfenol, dick- tylfenol och dinonylfenol. " Lämpliga monoaminer är metylamin och etylamin, vilka båda är kommersiellt tillgängliga. Föreningen med formeln C bör för erhål- lande av en snabb reaktion med den primära eller sekundära_aminerade hydroxylföreningen vara alfamonohalogenerad. Exempel på sådana före- dragna alfa-monohalogenerade föreningar är monoklorättiksyra, alfa- monoklorpopionsyra och alfa-monoklorsmörsyra samt monokloretansul- fonsyra, alfa-mcnoklorpropansulfonsyra och alfa-klorbutansulfonsyra.In addition to aliphatic alcohols, cycloaliphatic and, above all, aromatic hydroxyl compounds can also be used as starting material. Suitable cycloaliphatic alcohols are cyclohexanol, cycloheptanol, cyclooctanol, cyclododecanol and cyclohexadecanol. Of the suitable aromatic hydroxyl compounds, particular mention should be made of synthetically produced mono- and dialkyl-substituted phenols, such as octylphenol, nonylphenol, dodecylphenol, hexadecylphenol, dibutylphenol, dictylphenol and dinonylphenol. Suitable monoamines are methylamine and ethylamine, both of which are commercially available. The compound of formula C should be alpha monohalogenated to obtain a rapid reaction with the primary or secondary aminated hydroxyl compound. Examples of such preferred alpha-monohalogenated compounds are monochloroacetic acid, alpha monochloropopionic acid and alpha-monochlorobutyric acid as well as monochloroethanesulfonic acid, alpha-monochloropropanesulfonic acid and alpha-chlorobutanesulfonic acid.
AN föreningar med formeln A bör framförallt framhållas alfa-amino- föreningar, även om t ex betaaminoföreningar i princip kan användas.AN compounds of the formula A should above all be emphasized alpha-amino compounds, although, for example, beta-amino compounds can in principle be used.
Speciellt kan nämnas metylglycin, metylalanin och metylvalin samt metyltaurin; ' Den amfiotära föreningens floteranäe förmåga kan ytterligare förstärkas genom närvaro av en hydrofob-sekundärsamlare, företrädes- vis i form av en polär, vattenolöslig, hydrofob substans med affini- ...,.-... ....._. ........... .....-,--.....__..',. ..-. ..-__ _... - _. --.~.-__.«.~__...... ....-....__.._,.... .. ...__ .H .. -.._ ..- . ...__ . .-.___ ..._ --._.,.._... \ -- ------Ir..? _.. ...L S: :::-__.--.-.;.~.~.:.,....\_- < ., s 7802427-0 tet till de mineralpartiklar, som överdragits av den amfotära före- ningen. Den amfotära föreningen tillsättes vanligtvis i en halt av 50 --1000, företrädesvis 100 - 750 g per ton mineral och den po- lära, vattenolösliga, hydrofoba substansen i en mängd från 0 - 1000 g, företrädesvis 5 - 750 g per ton mineral. I det fall både den amfotära föreningen och den hydrofoba substansen användes kan förhål- 'landet dem emellan varieras inom vida gränser men det ligger vanligt-_ vis inom intervallet 1:20 - 20:l, företrädesvis 1:5 - 5:1. Den vatten- olösliga hydrofoba substansen, som enligt uppfinningen kan betecknas som en sekundärsamlare utgöres företrädesvis av en polär substans, som eventuellt lösts i ett kolväte. För att erhålla en stabil emul- sidn i vatten och en god fördelning kan man även tillsätta en konven- tionell emulgator t ex en nonjonisk ytaktiv förening, vilken i det fall den är vattenolöslig skall inräknas i den polära substansen.Mention may be made in particular of methylglycine, methylalanine and methylvaline and methyltaurine; The flotation capacity of the amine compound can be further enhanced by the presence of a hydrophobic secondary collector, preferably in the form of a polar, water-insoluble, hydrophobic substance with affine ...,.-... ....._. ........... .....-, --.....__ ..

The amphoteric compound is usually added at a level of 50-1000, preferably 100-750 g per tonne of mineral and the polar, water-insoluble, hydrophobic substance in an amount of from 0 to 1000 g, preferably 5 to 750 g per tonne of mineral. In case both the amphoteric compound and the hydrophobic substance are used, the ratio between them can be varied within wide limits, but it is usually in the range 1:20 - 20: 1, preferably 1: 5 - 5: 1. The water-insoluble hydrophobic substance, which according to the invention can be described as a secondary collector, is preferably a polar substance, which is optionally dissolved in a hydrocarbon. In order to obtain a stable emulsion in water and a good distribution, it is also possible to add a conventional emulsifier, for example a nonionic surfactant, which, in the event that it is water-insoluble, is to be included in the polar substance.
Lämpliga polära kmnponenter är vattenolösliga tvàlar såsom kalcium- tvâlar; vattenolösliga ytaktiva alkylenoxidaddukter; organiska fos- fatföreningar, såsom tributylfosfat och tri(2-etylhexyl)fosfat; och estrar av karbonsyror,sàsom tributylester och tri(2-etylhexyl)ester av Nfc-A, samt dioktylftalat. ' Vid tillämpning av förfarandet enligt uppfinningen kan man även på i och för sig känt sätt tillsätta pH-reglerande substanser samt tryckande och aktiverande substanser. I de flesta flotations- ~-° fikfarandenär pH-värdet av betydelse för erhållande av en god sepa- ' ration. Flotationsförfarandet enligt uppfinningen är också beroende av pH-värdet, vilket ger ökade möjligheter att optimera separationen av olika mineraler genom lämpligt pH. Således varierar den amfotära ytaktiva föreningens karaktär avsevärt med pH-värdet. I stark sur miljö är den övervägande katjonisk medan den i alkalisk miljö, exem- pelvis vid ett pH-värde av 10 är övervägande anjonisk. Vid separation av malm innehållande apatit och silikat eller apatit och kalcit er- hålles en god selektiv anriktning om flotationen utföres vid pH-vär- den omkring 8 - ll. Om man så anser lämpligt kan man även tillsätta 'i och för sig kända skumbildare och tryckande och aktiverande reagens.Suitable polar components are water-insoluble soaps such as calcium soaps; water-insoluble alkylene oxide adduct additives; organic phosphate compounds such as tributyl phosphate and tri (2-ethylhexyl) phosphate; and esters of carboxylic acids, such as tributyl ester and tri (2-ethylhexyl) ester of Nfc-A, and dioctyl phthalate. When applying the process according to the invention, it is also possible to add pH-regulating substances as well as pressing and activating substances in a manner known per se. In most flotation procedures, the pH value is important for obtaining a good separation. The flotation process according to the invention is also dependent on the pH value, which provides increased possibilities to optimize the separation of different minerals by suitable pH. Thus, the nature of the amphoteric surfactant compound varies considerably with the pH value. In a strongly acidic environment it is predominantly cationic while in an alkaline environment, for example at a pH value of 10 it is predominantly anionic. When separating ore containing apatite and silicate or apatite and calcite, a good selective enrichment is obtained if the flotation is carried out at pH values around 8 - 11. If deemed appropriate, it is also possible to add per se known foaming agents and pressing and activating reagents.
Några generella regler kan icke uppsättas, eftersom varje malm slut- giltigt måste behandlas med hänsyn till sin egen kemiska och fysi- kaliska sammansättning.No general rules can be set, as each ore must be finally treated with regard to its own chemical and physical composition.
