| titleOfInvention | Enrichment process for molybdenum from molybdenum and alkaline carbonate, sulfate, hydroxide or hydrocarbonate and eventually uranium containing solutions |
| abstract | PRECISION OF DISCLOSURE: Process for recovering molybdenum from aqueous solutions to be purified containing, in addition to said molybdenum, carbonate sulfate, hydroxide or hydrogen carbonate alkaline and may also contain uranium, as well as mineral and / or organic impurities, said solutions being treated at a temperature at most equal to boiling with lime, to transform the carbonate alkaline to hydroxide and precipitate calcium salts insol-lubles formed, then to separate and wash the first precipitate containing essentially calcium carbonate, of a liquor which has been enriched with alkaline hydroxide which is center by evaporation at the same time as the washing liquor of the first precipitate, until a hydroxide content is obtained alkaline at most equal to 50% to cause obtaining a second precipitate formed from a mixture of molybdate and sul-alkaline fate, characterized in that this solid mixture is dispersed in an acidic aqueous liquor, heated to 120 ° C and 250 ° C under pressure, so as to cause the precipitation anhydrous MoO3, which is subsequently separated from the mother liquor mainly containing alkaline sulphate. |
