LIQUID SUSPENSION SEPARATION OF SATURATED FILTER MEDIA IN SLURRY FORM

摘要

In the method for recovering mercury from carbonaceous filter aid used in filtration of mercury cell alkali metal hydroxide solution to remove mercury therefrom, the steps which comprise: slurrying the filter aid in a liquid medium, allowing the slurried filter aid to settle to form a mercury-rich filter aid slurry stratum and a supernatant mercury-lean filter aid slurry stratum, and separately recovering the mercury-rich stratum.
