The milling (refining) process extracts uranium oxide (U 3 O 8) from ore to form yellowcake, a yellow or brown powder that contains about 90 percent uranium oxide. [6] Conventional mining techniques generate a substantial quantity of mill tailings waste during the milling phase, because the usable portion is generally less than one percent of the ore.

Mining Milling Once an economic uranium deposit is found, preparation for the first stage of the fuel cycle – mining and milling – can begin. Today, uranium is mined in 19 countries around the world. The leading producer is Kazakhstan, followed by Canada and Australia. These three countries account for about 64% of world production.
