French term (edited):
liqueur m�re de cristallisation sur r�sine ch�latante
Selected
mother liquors from crystallization on a resin ...
...In an industrial setting, the solute-solvent mixture is commonly referred to as the "mother liquor".
...Equipment Used in Crystallization
1. Tank Crystallizers
This is probably the oldest and most basic method of crystallization. In fact, the "pot of salt water" is a good example of tank crystallization. Hot, saturated solutions are allowed to cool in open tanks. After crystallization, the mother liquor is drained and the crystals are collected. Controlling nucleation and the size of the crystals is difficult. The crystallization is essentially just "allowed to happen". Heat transfer coils and agitation can be used. Labor costs are high, thus this type of crystallization is typically used only in the fine chemical or pharmaceutical industries where the product value and preservation can justify the high operating costs.....

The cyclophexanol or KA oil is further oxidized to adipic acid with nitric acid in the presence of copper and vanadium salts as catalysts. Crude ADA is crystallized and purified from the oxidation reaction solution. After crystallization, the waste mother liquor comprises an aqueous nitric acid solution containing copper and vanadium along with dicarboxylic acid by-products. Catalyst and nitric acid are recovered and recycled, organic acid by-products are used for the production of polyester polyols which are consumed in the polyurethane production.
The valuable copper and vanadium catalysts are removed from the waste mother liquor by passing through a cation exchange resin bed. These metals are then recovered by passing nitric acid through the spent cation exchange resin during the ion exchange resin regeneration. The concentrated metal-containing nitric acid solution can be then sent back to the oxidation reactor.

I am afraid I can't find anything about the word "chélatante". Are you sure about its spelling?

Yes, it makes sense now. But then, may it should be \"through or over chelating resin\"???

Well, my final suggestion is: \"MOTHER LIQUORS AFTER CRYSTALLIZATION ON A CHELATING RESIN\".
Look at this quote, too:
By detergent-mediated dissociation of pure LHCII trimers, recombinant monomeric proteins were obtained from which only recombinant monomers were retained on a nickel-chelating resin by affinity chromatography....

: My understanding of "mother liquor" is that it is the liquid left over after a crystallization, electrolysis, or the like. But it is certaily applicable here.

liqueur m�re de cristallisation sur r�sine ch�latante
[treatment of...] cristallization mother liquors on chelating resin
Presumably the chelating resin is to remove something (the palladium?) from the liquor before crystallization.
Discussion
Thanks for your input.
As to ch�latante, yes, that's what my text says. Ch�latant translates as Chelatant in mineral chemistry, agent ch�latant, chelating agent, etc. It's probably *chelating resin*.
