Hi all
I am translating a piece about the history of coal mining in Belgium and have come across the above terms twice in the following contexts:
'Brute steenkool bestaat in gewicht uit circa 50% steenkool en 50% stenen, in volume uit 2/3 steenkool en 1/3 stenen. Bij het wassen van de steenkool worden de mee aangevoerde of aangeklitte stenen gewoon verwijderd. In de laatste decennia verloopt dit proces volledig mechanisch. In verzwaard water of pulseerbedden worden ze van elkaar gescheiden doordat de stenen zinken en de steenkool blijft drijven.'
and
'Om te vermijden dat die via de oude wasserijtoestellen op de terrils belandt, moeten de kolenwasserijen met steeds fijnere wasprocédés uitgebreid worden, zoals pulseerbakken voor fijnkool en recuperatie-installaties voor stofkool (flotatie).'
The only usage of 'pulseerbakken' I could find online was here: http://cosimo.be/paginas/de_grote_sprong_voorwaarts_nieuwe_i... (and I couldn't find any for 'pulseerbedden'). I would appreciate any advice on this. Thank you in advance.

pulsating bed separator; jig
'· Jigs: In this application raw coal is introduced into a pulsating bath of water. The raw coal is moved across a perforated plate with water pulsating through it. A stratified bed of material is established with the heavier rock at the bottom and the lighter coal at the top. At the discharge end, the refuse is removed from the clean coal. Typical size ranges treated in a jig are 75 mm to 12 mm. There are special application fine coal jigs which use an artificial bed of feldspar rock.' (http://www.ilo.org/safework_bookshelf/english?content&nd=857...
'Coal Washing - There are two coal cleaning processes that predominate in the industry: dense medium (DM) separation and JIG washing. JIG washing, which is a water-based process that relies on the pulsation of water through the particle bed to stratify particles of different density, is widely perceived as a simpler, lower-cost option than DM separation.')
'4. Pulsating bed separation
This method uses a pulsating water flow through a particle bed to effect separation. In the mining industry, the pulsating bed or jig has been in use for many decades to concentrate valuable minerals like gold and tin, for cleaning coal, concentrating bulk minerals like iron but also for removal of contaminants from gravel and sand. Nowadays, the jig is also used in the secondary raw material industry, like the handling of car-scrap.' (http://www.biosoil.nl/app/attach/NcFxmAhT/115000/57836ff7d81...
