Separation of smallest size scrap breakout diamond melee from CZ (2 replies)
Please join and login to participate and leave a comment.
About this problem, I found out when developing design of the Device for freezing CZ's without harmful hydrofluoric acid.
If I understand correctly, such a problem may arise after the sieving large quantity of diamonds with the smallest size (0.8 to 1 mm) and right now it is solved by separation "frozen" SZ's from diamonds manually. Such tiny diamonds weigh about 0.2mg each, because of static electricity they stick to walls and tweezers, they are difficult to hold, they "jump", and disappear without a trace. This is an ungrateful manual work requiring attention and stress.
Conceptually, I have already decided the problem of sorting CZ's from tiny diamond melee according to their density. This is a simple desktop Device, where water separates gems (see pic). It works and sorts diamonds from CZ's by 100%.
Right now one-time download of my design is 15-20 ct tiny diamonds of the same size. Is it enough for practice or it’s necessary to scale the device?
In addition, I know nothing about a problem with separation from Zircon (d = 4.7 g/cc) and Moissanite (d = 3.2 g/cc). Does this procedure need for practice?
So, to whom may be interesting the device for separation of diamonds from impurities? Or, maybe the best way is to send the smallest melee e.g. to India?
