Those ores aren't particularly heavy compared to gold. Seems you'd have modify the process in order to capture those ores as opposed to gold. Nobium is not that heavy, but tantalum and uranium are both pretty heavy, both much heaiver than lead and it can be caught pretty easy in a dredge, tantalum's specfic gravity is around 16.6, uranium is around 18.7, most anything with a specfic gravity of over 10 or 11 can be caught in a dredge pretty easy. 2 Quote Link to comment Share on other sites More sharing options...
