The technical excellence of separation achieved in a mineral concentration process, or any other process where two constituents of any kind are physically separated from each other, is expressed uniquely and quantitatively by the Separation Efficiency: Es = (R Rg) where R is the percentage of the valuable constituent and Rg the percentage of the waste appearing in the concentrate. The
Jan 01, 1981· Grade efficiency As the performance of most available separational equipment is highly size-dependent (i.e. different sizes are separated with different efficiency), the total efficiency defined in eqn. (2-5) (or 2-6) depends very much on the size distribution of the feed solids and is, therefore, unsuitable as a gen eral criterion of efficiency.
Separation efficiency is defined as the ratio of concentration that has been removed from the feed stream to the initial concentration in the feed stream, shown in Eq. (1). In every technology it is governed by the physico-chemical properties of the contaminants and operating conditions at which the process units work, PP tc. Coagulant dose, flocculation energy input and time dictate the extent of
The lower separation limit of dense medium hydrocyclone and the upper limit of flotation machine are 0.5mm. However, in actual production, the separation efficiency of dense medium hydrocyclones for fine-grained is low, and the separation efficiency of coarse-grained grade is low, which leads to the ineffective separation of coarse coal slime between them, which will easily cause the problems
