NRC: Conventional Uranium Mills
Trucks deliver uranium 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 ...
Uranium | The Canadian Encyclopedia
Uranium oxide was first identified in 1789 by M.H. Klaproth in the mineral pitchblende, but its distinctive property of radioactivity was discovered much later (1896) by Henri Becquerel. The subsequent discovery in 1898 of the elements polonium and radium led to the development of the radium industry, in which Canada played an important part.

Uranium: Known Facts and Hidden Dangers
When we extract uranium from the ground, we dig up the rock, we crush it and we leave behind this finely pulverized material -- it's like flour. In Canada we have 200 million tons of this radioactive waste, called uranium tailings. As Marie Curie observed, 85 percent of the radioactivity in the ore remains behind in that crushed rock.
