Patent DE-2403549-A1 (DE)
Title: Wetting out powdered materials - using froth as the wetting agent
Inventor: KRAUSE HEINZ JOSEF
IPC: C04B33/18
Filed: 1974-01-25
Abstract: Powdered materials such as clay, ore dusts, coal dust soot etc. are wetted out with water by bringing the powder into contact with an aerated aq. froth and mixing the two. The optical and/or chemical properties of the resulting mixture can be improved by additives to the water used for making the froth. Froths have a large effective surface area and individual solid particles are more easily dispersed in them. This causes much reduced mixing time, reduced lump formation and no need for additional equipment for size reduction.
