Abstract: Highly concentrated pumpable hydrosulphite pastes which are free of sediments are prepared from solid and liquid feed materials by continuously mixing and dispersing pulverulent sodium dithionite (2) and an organic liquid (8) inert towards sodium dithionite in an intensive mixer (5) comprising mixing and dispersing elements arranged in steps.
