    Milling. Uranium milling involves extracting uranium from mined ore. The ore is crushed into sand size particles and the uranium is leached out. The uranium then is precipitated out of the leaching solution and dewatered dried and packaged. Through the extraction process uranium is concentrated into a product referred to as "yellowcake."
