Formatted Abstract/Summary Water recycling is of prime importance in mineral processing due to consumption of large amount of
water. This issue is vital in areas with a low rainfall such as Shahre-Babak (Kerman. Iran). Deep cone
thickeners. unlike conventional thickeners. have a low diameter to height ratio where large amounts of
flocculants are used to increase particles settling rates. The high bed heights (over 10 m) produce
enough pressure to create a paste type underflow indicating maximum water recovery. Flocculent
preparation, conditioning, and distribution along with the bed height are among the important factors
affecting the performance. Four deep cones are used to recover water from the tailings of the plant.
Plant data indicated that the thickener never reached the target underflow percent solids (63%) and
the average underflow concentrations were between 49 and 57%. By modification and optimization of
flocculent preparation and distribution methods the underflow percent solids increased by 3-4%. This
translated to an increase of water recovery from 67 to 73%. This was equivalent of 53000 m3 saving in
monthly water consumption.
