Liquid-liquid centrifugal extractor

A method of liquid-liquid centrifugal extraction, comprising the steps of:

• rotating a shaft;
• introducing a first and a second liquid into a first mixing chamber;
• mixing the first and second liquid inside the first mixing chamber by rotating the shaft;
• separating the first from the second liquid by means of a separator mounted on the shaft;
• extracting one of the first and second liquid from a first collecting chamber;
• the mixing of the first and second liquid inside the first mixing chamber is carried out along a first axial section of the shaft and the separating of the first from the second liquid with the separator is carried out along a second axial section of the shaft, the second axial section of the shaft being spaced from the first axial section in axial direction of the shaft.
