'''Ore Mills''' are [[Mills]] used to grind the ore such as copper and uranium, into a fine powder so the copper minerals can be separated by flotation. Trucks deliver ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore. (In addition to extracting 90 to 95 percent of the uranium from the ore, the leaching agent also extracts several other "heavy metal" constituents, including molybdenum, vanadium, selenium, iron, lead, and arsenic.) | |||
