  1. Analysis, delineation and evaluation of separation processes

  2. Separation (for instance flotation)

  3. Elements of separation process: Delineation, Analysis, Evaluation

  4. Delineation Quantity and quality of products

  5. Delineation Main feature and its building parameters Material main feature Other factors (fluctuations) Fields, space time provided by separator

  6. ANALYSIS

  7. Structure of separation by flotation

  8. ANALYSIS Components: type

  9. ANALYSIS Components: features -name -quantity -quality -economical value -main feature providing separation -features forming main feature -time of components displacement -separating forces acting on components -ordering and other forces acting on components -other (temperature, pressure, etc.)

  10. ANALYSIS Components: types and feaures fractal-like structure

  11. ANALYSIS Features can be grouped into families

  12. ANALYSIS Taking into account four families value Their combination provides different

  13. ANALYSIS

  14. Flotation, as a rule, is analyzed as upgrading

  15. ANALYSIS UPGRADING AND ITS BALANCE (Analysis of separation taking into account content (mass or similar paremeters of the system)) YIELD ()

  16. ANALYSIS UPGRADING AND ITS BALANCE CONTENT Amount of a component (fraction, type of grain, etc.) in a product, usually in % Used symbols

  17. Infinitive number of upgrading parameters can be derived from ,  and  Most popular are: Recovery: Cumulative recovery Upgrading ratio k=l/a K=b/a ANALYSIS

  18. ANALYSIS Other parameters, for instance e1-e2, l1-l2 e1/e2 ,e1e2

  19. Typical upgrading balance (for feed and final products) ANALYSIS  (%)  ()/100% way of calculating content of considered component in feed

  20. ANALYSIS Upgrading balance

  21. ANALYSIS Principle upgrading curves constant Henry’s: = f() Mayer’s  = f() Halbich’s:  = f () Fuerstenau’s: 1 = f (2)

  22. EVALUATION Henry’s

  23. EVALUATION Mayer’s

  24. EVALUATION Halbich’s

  25. EVALUATION Fuerstenau’s

  26. Comparison

  27. Upgrading (quality versus quantity) -insensitive upgrading curve) e.g. Fuerstenaua upgrading curve)

  28. why Fuerstenau’s upgrading curve? -universal - insensitive -easy to use mathematical eqs -low self-similarity (provide real R2) -allows comparison of different comp. -and more

  29. Fuerstenau’s (recovery-recovery or -) vs Halbich’s (grade-recovery or β- ) upgrading curves Fuerstenau’s is α-insensitive equivalent to Halbich’ upgrading curve

  30. Fuerstenau’s and Halbich’s upgrading curves (two in one)

  31. Mayer’s vs MDTW’s upgrading curves α-sensitive α-insensitive
