The invention claimed is: 1. Method of fractionating liquid mixtures or solutions, comprising the steps of subjecting a feed in the form of a liquid mixture or solution comprising three or more components to a first chromatographic separation, thereby recovering at least a fraction (A) and a fraction (B) both containing a first component or product, which is in the middle of eluting components in a dry solids profile of said eluting components, subjecting a mixture or solution derived from or comprising said fraction (A) to a second chromatographic separation, thereby recovering at least a fraction (C) which has a higher weight percentage of said first component or product than the feed, and subjecting a mixture or solution derived from or comprising said fraction (B) to a third chromatographic separation, thereby recovering at least a fraction (D) which also has a higher weight percentage of said first component or product than the feed, and whereby at least two fractions are recovered from the second and third chromatographic separations. 2. Method according to claim 1, wherein said first and/or said second and/or said third chromatographic separations are effected by way of a simulated moving bed method. 3. Method according to claim 1, wherein said first chromatographic separation is effected by way of a simulated moving bed method and said second and third chromatographic separations are effected by way of batch chromatographic methods. 4. Method according to claim 1, wherein in said first chromatographic separation a fraction (E) rich in said first component or product is recovered. 5. Method according to claim 1, wherein in said first chromatographic separation a fraction (F) rich in a second component or product is recovered. 6. Method according to claim 5, wherein said second component or product is sucrose. 7. Method according to claim 5, wherein said second component or product is an acetic acid or an acetic acid containing fraction. 8. Method according to claim 1, wherein in said first chromatographic separation a fraction (G) rich in a third component or product is recovered. 9. Method according to claim 8, wherein said third component or product is salt. 10. Method according to claim 1, wherein in said second and/or said third chromatographic separation a fraction (H) rich in said second component or product is recovered. 11. Method according to claim 1, wherein in said second and/or third chromatographic separation a fraction (I) rich in said third component or product is recovered. 12. Method according to claim 1, wherein in said first, second and/or third chromatographic separation a fraction (J) rich in a fourth component or product is recovered. 13. Method according to claim 12, wherein said fourth product is betaine. 14. Method according to claim 5 or claim 12, wherein said second and/or fourth component or product is xylonic acid. 15. Method according to claim 6 or claim 12, wherein said third and/or fourth component or product is lignosulphonate. 16. Method according to claim 1, wherein in said first, second and/or third chromatographic separation a fraction (K) rich in a fifth component or product is recovered. 17. Method according to claim 1, wherein a fraction (L) is recovered in said second and/or third chromatographic separation and returned into said first, second and/or third chromatographic separation. 18. Method according to claim 17, wherein fraction (L) is admixed with said feed and/or said mixture or solution derived from or comprising fraction (A) and/or said mixture or solution derived from or comprising fraction (B). 19. Method according to claim 1, wherein a fraction (M) is recovered in said first chromatographic separation and returned into said first chromatographic separation. 20. Method according to claim 19, wherein fraction (M) is admixed with said feed. 21. Method according to claim 1, wherein said fraction (M) is rich in the first component. 22. Method according to claim 1, wherein said fraction (A) and fraction (B) have become poorer in relation to the second or third component or product respectively. 23. Method according to claim 1, wherein said feed is sugar beet molasses, sugar cane molasses, wood molasses or wheat molasses. 24. Method according to claim 23, wherein said first component or product is raffinose. 25. Method according to claim 1, wherein said feed is sulphite cooking liquor. 26. Method according to claim 25, wherein said first component or product is xylose. 27. Method according to claim 1 wherein the feed is selected from stillage, vinasse, glucose-fructose syrup, maltose syrup, maltitol syrup, starch hydrolyzate syrups, lactose-lactulose syrup and prehydrolysates as well as solutions or mixtures derived therefrom. 28. Method according to claim 1, wherein the simulated moving bed chromatographic separation is sequential or continuous. 29. Method according to claim 28, wherein the loops are open and/or closed. 30. Method according to claim 29, wherein a solution derived from a fraction in one of the loops is transferred or passed to another loop when the loops are open. 31. Method according to claim 28, wherein each loop comprises a series of columns, beds or parts thereof and each loop has at least one column, bed or part thereof which is separate and apart from one or more of the other loops. 32. Method according to claim 28, wherein each loop is separate and distinct from the other. 33. Method according to claim 1, wherein one or more of the chromatographic separations is effected with the aid of a strong acid cation exchange resin. 34. Method according to claim 1, wherein water is used as an eluent. 35. Method according to claim 1, wherein at least said second and third chromatographic separations are effected in parallel loops. 36. Method according to claim 1, wherein fractions taken from said second and/or third chromatographic separation are subjected to further chromatographic separation in one or more further loops which may be parallel.
