[QUOTE="grubstake, post: 422621, member: 4012"] I'm not an engineer or a metallurgist and I guess you aren't either, but I've worked with enough of them to have an inkling of why your 'quick and dirty' demo didn't achieve the desired outcome. I don't think you're on the wrong track, but as a solution to the thorny problem of separating fine gold from black sand, fluidising is probably much more complex than it might at first appear. I believe that every component of the process is a variable that will have an effect on the result. eg. container dimensions, water flow rate, particle size, etc. These and more will all alter the percentage of gold recovered. You may even need a supplementary chemical treatment to change the water surface tension (a drop or two of detergent might do it). With enough experimentation, I reckon you'll eventually refine the process to achieve worthwhile yields. In the meantime, unscripted stuff like the dog walking past and the wind gusting, made for some classic moments - thanks for sharing them. [/QUOTE]
