A model was developed for the FO concentration process utilizing low-concentration sucrose solutions (0.1–0.6 m) and NaCl solution (10% and 23%) as an osmotic solution (Dova, Petrotos, Lazarides, 2007a, 2007b).The flux increased proportionally with the concentration of draw solute; however, mass transfer coefficient reduced by 75% with increase in osmotic solution concentration (Fig. 11 A ...

The gravity separation process is also known as hydraulic method or levigation. The gravity separation process is based on the differences in the gravity of the ore and the gangue particles that are present in the ore. Complete step by step answer: We know that the gravity separation process is used for the concentration of ore.
