discharged from the bottom of the separator). Assuming free settling, what upward velocity of water is required to achieve this? What range of galena particle sizes will appear in the overflow (materials stream discharged from the top of the separator)? Would better or worse separation be achieved if: a) a more viscous fluid was used? b) a denser fluid was used (but keeping fluid density less than 2650 kg/m?) c) a narrower particle size distribution was achieved?

Q4. A mixture of quartz and galena of size 70 to 200 micrometer is to be separated by differential
elutriation in water at 20 °C. It is required to have pure galena in the underflow (materials stream
discharged from the bottom of the separator). Assuming free settling, what upward velocity of water is
required to achieve this? What range of galena particle sizes will appear in the overflow (materials
stream discharged from the top of the separator)? Would better or worse separation be achieved if:
a) a more viscous fluid was used?
b) a denser fluid was used (but keeping fluid density less than 2650 kg/m?)
c) a narrower particle size distribution was achieved?
Density of galena = 7500 kg/m?,
Density of quartz = 2650 kg/m³,
Density of water = 1000 kg/m?,
Dynamic viscosity of water = 0.001 Pa-s.
