Carbonate leach uranium ore processing with sodium

Carbonate leach uranium ore processing with sodium

In a process system where uranium values in a water slurry of crushed uranium ore are treated by a solution of carbonate in system water to convert the uranium to a soluble uranyl tricarbonate ion, the slurry then being filtered to remove waste solids delivered to a tailings pond containing system water, and the filtrate being separately treated to precipitate uranium oxide: the improvement characterized by adding to the slurry, fed to the filter, sodium

The soda-ash roasting of chromite ore processing residue

The soda-ash roasting of chromite ore processing residue

Abstract. Sodium chromate is produced via the soda-ash roasting of chromite ore with sodium carbonate. After the reaction, nearly 15 pct of the chromium oxide remains unreacted and ends up in the waste stream, for landfills. In recent years, the concern over environmental pollution from hexavalent chromium (Cr 6+) from the waste residue has become a major problem for the chromium chemical

Aug 05, 2021 Abstract. Hexavalent chromium in soda ash Chromite Ore Processing Residue (COPR) is harmful to the environment, it is imperative to develop a low cost, efficient, and effective treatment. Herein, a new method (ball milling + sodium sulfide) was developed for mechanochemical treatment of water-leached COPR (W-COPR, about 900 mg/kg non-exchangeble Cr (VI) and mostly chromite

Additives in Selective Reduction of Lateritic Nickel Ores

Jul 07, 2021 In this work, the selective reduction of lateritic nickel ore was carried out using sodium sulfate, sodium carbonate, and sodium chloride as additives. The 5 wt% of anthracite coal, which contains 60.35% of fixed carbon and 1.9% of sulfur, was used as a reductant. All raw materials were mixed homogenously prior to the pelletization process into 10–15 mm of diameter. The reduction process
