Filter cake treatment method

摘要

A method of separating metal particulates form a slurry of liquid metal and metal particulates and salt particulates by filtering the slurry to form a cake of metal and salt particulates with some liquid metal. The cake is broken and liquid metal is removed by vacuum distillation or with a hot inert sweep gas at either positon or negative pressure from the broken cake, and thereafter separating the metal and salt particulates. Thereafter, the metal partucilates are sized before water washing to prevent unacceptable explosions upon contact with water.
