Uranium Ore assaying approximately % U3O8, slightly under 1% V205 and % CaCO3 is received at the mill from company owned and operated mines and from custom ore suppliers. Virtually all of the production from the company mines is carnotite .

Uranium Refining As already stated under the description of the precipitation of uranium, most of the sodium uranate that is obtained contains 7 to 9 per cent of V2O5 on the dry basis. It has been impossible to precipitate sodium uranate in alkaline solution containing both uranium and vanadium and not precipitate at the same time a considerable amount of vanadium with the uranium .

History of Uranium Production in Canada. Uranium was first discovered in Canada in the mid1800s on the north shore of Lake Superior. However, uranium ores first came to public attention in the early 1930s when the Eldorado Gold Mining Company began its operations at Port Radium, Northwest Territories (Great Bear Lake), to extract its radium content.

The modern uranium mining industry, however, began in the 1940s, primarily to produce uranium for weapons. Most early uranium mines were converted from former vanadium or radium mining and processing sites. Since the 1970s, uranium has primarily been mined for use as nuclear fuel.

ORE PROCESSING AND REFINING OF URANIUM IN INDIA. Uranium ores of commercial importance in India are of comparatively low grade containing less than % of uranium. A mill for processing the ore has been operating for over 10 years. A plant for refining the yellow cake and producing uranium metal of nuclear purity was set up in 1959.

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.

The Standard Chemical Company operated a Radium refining mill from 1911 to 1922 in Canonsburg, PA. From 1930 to 1942, the company purified Uranium ore. The mill was in Pennsylvania in stead of Colorado (which would have been closer to the mines that produced the carbonite) because the processing of the ore required huge quantities of chemicals; these chemicals were available in Pennsylvania.
