The path from raw uranium ore to a form ready for final use in piles, reactors, or the enrichment process flows through many branching steps. The first step, called milling, changed raw ore into uranium concentrate, either black oxide (uranium oxide, U3O8) or soda salt (sodium diruanate, Na2U2O7), also known as "yellow cake."

The plant was shut down in 1932 due to a poor market, but reopened in 1942 to produce vanadium for the war effort. The mill was left abandoned along with several million tons of unprocessed ore. In 1946, the plant was torn down and a new one built on the site to recover uranium. Vanadium is still used in the process of hardening steel.
Union Carbide's mill at Slick Rock West began operation in 1957 using a uranium-vanadium upgrading technique to process ore mined from the surrounding area. The upgraded material was shipped to the Union Carbide …
Although heap leaching using sulfuric acid was introduced to the uranium industry in the 1950s, sodium carbonate–bicarbonate (alkaline) heap leaching of low-grade Ca-carbonate-rich uranium ores has recently gained popularity. This study presents the results of two column tests on a calcrete-type uranium–vanadium (carnotite) ore using a mixture of sodium …
ambitious goal hinges on achieving a daily ore production of 500 tons, with an anticipated yield of approximately 3,000 pounds of uranium per day. A successful ramp-up would achieve the annual ore production goal of 1 million pounds of uranium and 6 million pounds of vanadium.
First mined for radium and minor uranium until 1923, numerous companies sporadically operated small scale mining and processing facilities along the Dolores River. In 1931, a mill was constructed by Shattuck Chemical Co. to process vanadium ore. In 1944, the area was worked by the Union Mines Development Corp. for uranium/vanadium ore.
Carnotite, a complex of uranium and vanadium, is an example of such ores. Being oxidized, it is often found in association with highly friable, clayey minerals such as calcrete and the …

The Facility will be designed and constructed to recover uranium, vanadium and cobalt from ore mined both from mines owned by Western and ore produced by other miners.
INORGANIC CHEMICALS used in vanadium-uranium ore processing include sulphuric acid and liquid solvents. The ore is treated with sulphuric acid to dissolve the vanadium and uranium. liquid A solvent is then used toseparate the uranium, leaving the vanadium
Resources, uses, and market. Vanadium is the 22nd most abundant element in the continental crust and it accounts for approximately 0.014% of it (Rudnick and Gao Citation 2003); however, concentrations of at least an order of magnitude higher, and preferably two orders of magnitude higher are required for the economic recovery of vanadium from ore deposits.
Two times more vanadium extraction during the additional leaching time in the column A, compared to the uranium extraction (20% vs 10%), indicates that while after 142 days, uranium leaching process is in the slow leaching rate stage, but vanadium still is in the fast leaching rate stage (Ghorbani et al., 2013a). This is believed to be due to ...
Vanadium is recovered as a co-product during uranium processing such as in Utah upon treating ore from Colorado. Solvent extraction is employed to separate the vanadium and uranium fractions which is then followed by an ion exchange stage which leaves the vanadium in the acid solution.
iron introduced through grinding media or present in the ore. Carnotite, a complex of uranium and vanadium, is an example of such ores. Being oxidized, it is often found in association with highly friable, clayey minerals such as calcrete and the associated solid/liquid separation issues are a key factor in process route determination.
