Uranium processing - Springer Link

Comminution. To render uranium ore amenable to high uranium extraction by leaching, mined ore must be reduced in size to produce particles that can be readily slurried and, in some processes, to ex- pose the uranium minerals to the lixi- viant. Originally, conventional crushing and rod mill-ball mill circuits were used.3.

United Nuclear - Uranium Extraction Experiment

Place the barrel on the mill and let it run for approximately 2 hours. This will reduce the ore into a very fine dust. This is necessary so the extraction chemicals will be able to react with the ore material. If Ball Milling is not done, very little Uranium will be extracted. After 2 hours of milling, the ore is as fine as Talcum powder.
