Claim 6:
7. The refining method according to claim 1, wherein the refining method is carried out using a refining apparatus which comprises
a mixing unit, provided with a mixing inner cavity and at least two sample inlets and at least one sample outlet, the mixing inner cavity communicating with the outside through said at least two sample inlets and at least one sample outlet; and
a separating unit, comprising at least one salt removal device in communication with the sample outlet, wherein the salt removal device is provided with
a separation inner cavity,
a first density phase outlet and a second density phase outlet which communicatively connect the separation inner cavity with the outside, the second density phase outlet being located above the first density phase outlet, and
a mixed solution inlet arranged to avoid the first density phase outlet and the second density phase outlet and being communicated with the sample outlet of the mixing unit,
wherein a sample feeding assembly and a separation assembly are arranged inside the separation inner cavity, the sample feeding assembly being connected with the mixed solution inlet, and the separation assembly being connected with the sample feeding assembly,
wherein the separation assembly comprises at least two separation elements arranged in parallel and extending in the flow direction of the mixed solution, each of the separation elements comprising a circulation cavity for circulating the mixed solution and a hydrophilic medium filled in the circulation cavity; and
wherein the sample feeding assembly is capable of splitting the mixed solution into equal parts flowing into said at least two separation elements.
