I'm very novice in regards to precious metals extraction using leaching ... only a little more than maybe a few hours of research on the topic ... but one of the key issues/concerns i see is in regards to disposal of the treated black sand .....
my study so far indicates you have to do a thorough job of washing/rinsing all the black sand to remove "all" the pregnant solution from the sand ... but, after the washing/rinsing stage; what are the black sands classified as? ... if 99.99% of the solution is washed out of the sands, and then the sands are layed out to dry in the sunlight for days - what are the sands classified as from an enviro point of view? ... any insights at all appreciated ..... is there a standard procedure for disposing leached computer scrap? - as i haven't come across much intel about it yet.
Do you think the Eco-Goldex system is environmentally friendly enough for the washed/rinsed post-process black sand to be considered non-hazardous?
