| titleOfInvention | A kind of phosphor-bearing uranium ore that reduces leaches the method that acid consumes |
| abstract | The present invention provides a kind of method for reducing phosphor-bearing uranium ore leaching acid consumption, its step：(1) phosphor-bearing uranium ore is crushed to granularity for -32 mesh of mesh～-200；(2) phosphor-bearing uranium ore by step (1) after broken is placed in autoclave, adds sulfuric acid solution, the quality that sulphuric acid is added for phosphor-bearing uranium ore quality 6～12%, liquid-solid ratio (1～2)：1L/kg；Then oxygen or air are passed through into autoclave, in autoclave, oxygen to pressure is 0.3～0.7Mpa, it is 1.5～3.5Mpa to pressure to add air in autoclave, is heated up to temperature for 110～140 DEG C, reacts 2～4 hours in autoclave under agitation；(3) solid-liquid separation is carried out to the leaching ore pulp of step (2) gained；(4) ion exchange is carried out to the solution of step (3) gained or solvent extraction extracts uranium.The present invention can reduce acid consumption more than 30%, can shorten extraction time more than 50%, and in leachate, the concentration of phosphorus is low, is conducive to the process of leachate. |
