Flowing film concentration
WebTherefore, d2 will stay up in the fast-flowing layers of the film. Similarly, if two particles of density Oh and Ol (Oh > Ol) are considered: (P/Pa)ah < (P/Pa)a 1 Therefore, o 1 will stay up in the fast-flowing layers of the film. Under the "viscous" conditions the dispersive pressure P on a particle is given as: du P = 2.93 X 3/2 r/dy WebDevelopment of the gravity concentration flowsheet is discussed and the paper finishes with the description of two plants, one treating iron ore and the other cassiterite, as an indication of the diversity of gravity concentration flowsheets.
