Whereas Olympic Dam produces uranium only as a byproduct, rossing is a pure uranium producer. In spite of its very low grade it is economic because of its size and importantly the fact that the uranium minerals occur between the feldspar grains and it takes little grinding to achieve higher recoveries.

INTRODUCTION Athabasca Basin of northern Saskatchewan (and a small part of Alberta), Canada, is a major source of global uranium (U) supply. Uranium mined from the Basin comprised 22% of the world's supply in 2015, and, as of 2016, there are 225 000 tU of known economically mineable U in reserves in the Basin [1, 2].

Recent uranium mining. Canada's uranium production in 2001 was about 12,500 tonnes uranium (tU), one third of world mine output, all from mines in northern Saskatchewan. By 2007, the share of world uranium production had decreased to 23%, with just under 9500 tU produced that year in the country. Canada's uranium ore reserves are about 14% of ...

Uranium Mining Overview. (Updated August 2023) In the last 60 years uranium has become one of the world's most important energy minerals. It is mined and concentrated similarly to many other metals. While uranium is used almost entirely for making electricity, a small proportion is used for the important task of producing medical isotopes.
