FlottationLa flottation est une technique de séparation fondée sur des différences d'hydrophobicité des surfaces des particules à séparer. Elle est utilisée en minéralurgie pour séparer des minéraux entre eux et dans le traitement des eaux usées pour éliminer les graisses.

| Résumé : |
How many leather producers realise that the table-jelly they may have been served up for dinner a week ago could well have started its life in their own tannery ? Indeed the very same producer may well have dragged the hides from which the gelatine in the dessert was made, out of a washing or dehairing drum, or passed the same hide through a flesher or splitter. Would the secretarial staff know that the carbonless copy paper may contain derivatives of the same gelatine material?
Any photographes will have a reasonable idea as to where a particular ingredient (and a very important one it is) of the film in their camera originates. Fewer people may be aware that the pork pies in their lunch box, the marshmallows, pastilles, mints and wine gums they pick up at the local supermarket, all have gelatine incorporated into them and that this gelatine or its precursor will have originated in a tannery.
I will attempt to describe how this becomes possible in the following paper which is a description of the process of gelatine manufacture as practised by my company, Gelatine Products Ltd, which manufactures edible gelatines solely from bovine hide pieces and splits, collected from many UK tanneries. |
