Tech/Engineering - Petroleum Eng/Sci | | French term or phrase: retraitement du catalyseur récupération du platine | This is from a services contract for the reprocessing of spent catalyst. I'm confused by this jumble of words and I'm not sure which bit goes with which. Separately, I have translated "retraitement du catalyseur" as "reprocessing of catalyst" and "récupération du platine" as "platinum recovery".
PREAMBULE

As for punctuation, it could be intended to be:
- retraitement du catalyseur/récupération du platine OR
- retraitement du catalyseur (récupération du platine)
or something along those lines since they are intimately related.

Looks as if the following article explains it all:
The platinum-bearing catalysts now in such substantial use in the petroleum industry retain their high activity during many months of use, but ultimately they require to be replaced by fresh charges. The e@cient and economic recovery of the platinum from spent catalyst is therefore of great importance to the commercial success of catalytic reforming. [...]
The catalyst charge is made up of small spheres or pellets of alumina or silica-alumina, impregnated with up to one per cent of platinum. The value of this platinum is a substantial part of the cost of the catalyst, so that ability to recover it almost completely from the spent mass is of essential importance to the economic success of the various reforming processes.
