Abstract

Provided is a slurry treatment apparatus includes: a treatment tank for performing any treatment of a solid-liquid reaction, a solid-gas reaction, a gas-liquid reaction, and solid-liquid separation on a slurry containing a metal or a metal compound; a first pipe; a second pipe; and a pump, in which one end of the first pipe has a suction opening for sucking the slurry from the treatment tank, the other end of the first pipe is connected to a suction port of the pump, one end of the second pipe is linked to a discharge port of the pump, the other end of the second pipe is connected to a microbubble generator, and the microbubble generator includes a throttle that throttles a flow of the slurry and a gas supply tube for supplying gas to the throttle, and supplies microbubbles to the slurry in the treatment tank.
