| titleOfInvention | A kind of method that oxalic acid promotes photocatalytic semiconductor sulfide mineral bioleaching |
| abstract | The invention discloses a kind of methods that oxalic acid promotes photocatalytic semiconductor sulfide mineral bioleaching, belong to biological metallurgy technical field.Acidophilus iron sulfur-oxidizing bacteria leaches semiconductor sulfide mineral under addition 0.01-0.2g/L oxalic acid, illumination condition.Oxalic acid can be reacted with oxidisability photohole, increase the utilization rate of light induced electron, and then dramatically increase semiconductor vulcanization leaching of ores rate.Compared with the leaching result of 6000 Lux-8500 Lux of light intensity addition 0.01-0.2g/L oxalic acid does not add the leaching result of oxalic acid with 0 Lux of light intensity, its leaching rate increases 30.4-42.7%, compared with not adding the leaching result of oxalic acid with 6000 Lux-8500 Lux of light intensity, leaching rate increases 5.3-15.3%.Method of the invention can be improved photocatalysis efficiency, to significantly improve semiconductor vulcanization leaching of ores rate, so that semiconductor sulfide mineral is with more comprehensive utilization value and realizes that semiconductor sulfide mineral is of great significance as application of the photochemical catalyst on bioleaching field. |
