A process for recovering paraxylene from at least two feedstreams containing xylene isomers, wherein the at least two feedstreams comprise a paraxylene-lean feedstream having a paraxylene to total xylene isomer ratio of 0.40 or less, and a paraxylene-rich feedstream having a paraxylene to total xylene isomer ratio of greater than 0.80, and wherein the process comprises: directing to a paraxylene recovery zone the paraxylene-lean feedstream, the paraxylene recovery zone comprising at least one crystallization zone and at least one reslurry zone, wherein the at least one reslurry zone comprises at least one efficiency stage which is a first reslurry stage to produce an intermediate stage product, and a product stage downstream of the at least one efficiency stage, wherein the product stage is a subsequent reslurry stage to produce a final product, wherein at least a portion of the paraxylene-lean feedstream is directed to the at least one crystallization zone; separating an effluent of the at least one crystallisation zone in one or more solid/liquid separation devices so as to form a filtrate and a paraxylene cake; directing the paraxylene cake to the efficiency stage wherein the paraxylene cake is reslurried in a reslurry drum, before an effluent of the efficiency stage is separated in a solid/liquid separation device to provide a solid effluent and a liquid effluent; directing the solid effluent from the efficiency stage to the product stage where the solid effluent is reslurried in a reslurry drum; directing to the paraxylene recovery zone the paraxylene-rich feedstream, wherein at least a portion of the paraxylene-rich feedstream is directed to the product stage, wherein the paraxylene-rich feedstream comprises an effluent downstream of a second paraxylene recovery zone, or wherein the paraxylene-rich feedstream is derived from a selective toluene disproportionation unit or a selective toluene alkylation unit; extracting liquid from an effluent of the product stage in a solid/liquid separation device so as to provide a solid product stage effluent; recovering from the product stage of the paraxylene recovery zone a paraxylene containing product stream having a paraxylene to total xylene isomer ratio greater than that of the paraxylene-rich feedstream.. directing to a paraxylene recovery zone the paraxylene-lean feedstream, the paraxylene recovery zone comprising at least one crystallization zone and at least one reslurry zone, wherein the at least one reslurry zone comprises at least one efficiency stage which is a first reslurry stage to produce an intermediate stage product, and a product stage downstream of the at least one efficiency stage, wherein the product stage is a subsequent reslurry stage to produce a final product, wherein at least a portion of the paraxylene-lean feedstream is directed to the at least one crystallization zone; separating an effluent of the at least one crystallisation zone in one or more solid/liquid separation devices so as to form a filtrate and a paraxylene cake; directing the paraxylene cake to the efficiency stage wherein the paraxylene cake is reslurried in a reslurry drum, before an effluent of the efficiency stage is separated in a solid/liquid separation device to provide a solid effluent and a liquid effluent; directing the solid effluent from the efficiency stage to the product stage where the solid effluent is reslurried in a reslurry drum; directing to the paraxylene recovery zone the paraxylene-rich feedstream, wherein at least a portion of the paraxylene-rich feedstream is directed to the product stage, wherein the paraxylene-rich feedstream comprises an effluent downstream of a second paraxylene recovery zone, or wherein the paraxylene-rich feedstream is derived from a selective toluene disproportionation unit or a selective toluene alkylation unit; extracting liquid from an effluent of the product stage in a solid/liquid separation device so as to provide a solid product stage effluent;
