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

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

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

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

Typical upgrading balance ANALYSIS Typical upgrading balance  (%)  ()/100% way of calculating content of considered component in feed
