Abstract
A slurry is discharged from an attack tank and degassed. At the top of the tank there is an overflow for discharging a first slurry portion. A container communicates with a pump. A receptacle is disposed between the overflow discharge and the container and comprises a downwardly inclined connecting surface for conducting the first slurry portion to the container. A conduit leads from the bottom of the tank and opens into the receptacle to combine a second slurry portion with the first slurry portion.
