Two sources with knowledge of the matter say second-round bids are due later this month, with preliminary interest seen from Anglo American, OZ Minerals, Vedanta Group and Aditya Birla Group.
1 U 3 0 8 is the symbol for a chemical compound, uranium oxide, composed of three atoms of uranium to eight atoms of oxygen. Most chemical assays for uranium are expressed in terms of U 3 0 8, and ore purchases are made on that basis.
Preliminary treatment of ore may involve a roasting operation, a physical or chemical concentration step, or a combination of these. Chemical concentration involves leaching by either dilute sulphuric acid or sodium carbonate and recovery of uranium as ammonium uranate or sodium uranate (yellow cake) by precipitation with ammonia or with sodium hydroxide. The concentrate is treated chemically ...

Conventional uranium ore treatment mills create radioactive waste in the form of tailings, which contain uranium, radium, and polonium. Consequently, uranium mining results in "the unavoidable radioactive contamination of the environment by solid, liquid and gaseous wastes".
An environmental radioactivity survey carried out in the Sabugal region, Portugal, showed enhanced radioactivity levels in surface water streams related to water discharges from old uranium mines.

Canada is a country rich in uranium resources and a long history of exploration, mining and generation of nuclear power (for coverage of nuclear power, see information paper on Nuclear Power in Canada). To 2014, more uranium had been mined in Canada than any other country – 485,000 tU, about one
US Uranium Mining and Exploration. Uranium mining in the USA today is undertaken by few companies on a relatively small scale. Uranium exploration is undertaken by many companies, often going over areas that were mined in the 1950-80s.

Uranium Mining Overview (Updated February 2019) 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.
On this area, a low grade uranium ore leaching dump was situated, which was later removed during the remediation process of the site. Now, an underground remains that is slightly to moderately contaminated with heavy metals and radionuclides (HM/R) with restrictions of land use. Concepts for remediation of HM/R-contaminated sites and for the subsequent utilization of the HM/R-loaded plant ...
treatment of available uranium contributing to the groundwater plume through precipitation of the uranyl-phosphate mineral autunite, and 2) emplacement of secondary-treatment capacity via precipitation
A process is presented for pressure leaching lowgrade South African U ores. The results of the plant operation are presented in some detail, particularly those which have an important economic aspect. With the results of this study it is possible to evaluate the economic advantages and disadvantages

In the course of identifying a 77% increase in mineral resources, BHP Billiton has defined a 27% increase in uranium resources, to 2.24 million tonnes of uranium oxide (1.9 million tU), at the Olympic Dam mine in South Australia.
Ranger has been producing uranium from stockpiled ore since 2012, when mining operations ceased at the site. Under the existing authority from traditional land owners, mining and processing activities at Ranger must cease in January 2021, with final rehabilitation to be completed by January 2026. The feasibility study is being conducted on the basis of the Ranger Closure Plan, released earlier ...
