This process involves transferring one or more solutes contained in an initial liquid solution to another immiscible liquid (solvent). The solvent enriched with solute(s) is called the extract, while the initial solution depleted of solute(s) is called the raffinate.
The initial liquid solution and the solvent are brought into contact to perform the solute transfer. The two outgoing liquid phases, extract and raffinate, are separated by static decantation (decanter mixer) or centrifugal decantation (Rousselet Robatel centrifugal extractors type LX or BXP).

A decanter mixer stage consists of: LIGHT PHASE OUTLET HEAVY PHASE INLET Decanter • Construction materials: PE, PP, PVC, PVDF, PTFE (sizes 1 and 2 only), stainless steel (316L/Alloy C22). • Motorization : The pumping turbine is driven by an IP55 electric motor, which can also be EExde. The motor is connected to a static frequency converter for speed adjustment. • Viewing port: A viewing port at the end of the decanter allows observation of phase separation. • Cover: A glass or plexiglass cover (depending on size) can be placed on the decanter to limit evaporation. • Size: Rousselet Robatel offers six sizes of decanter mixers (1 to 6), each with several dimensional variants of decanters.
