Abstract

A method of dressing slurries, more particularly coal slurries, comprises mixing the slurry with selectively acting additive (e.g. oil, oil/water emulsion) and feeding the mixture to a separating apparatus (5) for the purpose of separation into a predominantly solid phase (21) and a predominately liquid phase (22). Homogeneous mixing of the slurry with the additive is undertaken by the separating apparatus. A device for performing the method comprises the separating apparatus (5), a pump (3) for feeding slurry in a container (1) along pipes (2, 4) to the separating apparatus (5), a container (6) for the additive and a mixing element (9) in the pipe line (4). The container (6) is connected to the mixing element (9) by a supply line (7) containing a flow control valve (8). An emulsifier may be provided for emulsifying the additive.
