does someone know if when you cement pm with copper in a aqua regia solution, if all gold fall to the bottom. i know that all pm will cement out of solution if done correctly. but my main concern is about small particle just flotting aroud.
so if i have 1g of gold in solution and i cement it with copper, i will have 1 g out of solution... but will i have 1 g at the bottom in a 24 hour standing period ?
