Basic Research on Coarse Slime Recovery with a Water Medium Fluidized Separator
A laboratory water medium fluidized separator (WMFS), which is 0.06 m in diameter and 1.5 m high, is designed based on fluidization technique and the principle of hindered settling in hydrodynamics. Then the separation principle of WMFS and the construction of the separation system are introduced. The coarse slime as feed is fluidized by upstream, and the feed is separated according to the different settling velocities (terminal velocities) of coarse slime in WMFS. The settling behavior of coarse slime in WMFS is researched and the effects of density and size on particle terminal velocity during the fluidization are analyzed, and the relations between the velocity of upstream, pressure drop and bed height in WMFS are discussed. The study and application results show that the fluidization technology can efficiently ben-eficiate coarse slime of - 1mm + 0.25mm with an Ep value of 0.074.
