situations the uranium can be quite slow to dissolve, demanding long leach times and possibly pressure leaching to achieve optimal recovery. Fine grinding may also be required with these ore types ahead of leaching in either agitated tanks or an autoclave. Pitchblende is the massive form of this mineral and frequently occurs in veins.
