Краткое описание
In this article, a hydrometallurgical method for the selective recovery of germanium from fly ash (FA) has been tested at pilot plant scale. The pilot plant flowsheet comprised a first stage of water leaching of FA, and a subsequent selective recovery of the germanium from the leachate by solvent extraction method. The solvent extraction method was based on Ge complexation with catechol in an aqueous solution followed by the extraction of the Ge−catechol complex (Ge(C6H4O2)32−) with an extracting organic reagent (trioctylamine) diluted in an organic solvent (kerosene), the relevant reaction probably being 2(C8H17)3N(org) + Ge(OH)4o(aq) + 3(C6H6O2)(aq) ↔ ((C8H17)3NH)2Ge(C6H4O2)3(org) + 4H2O(aq) followed by the subsequent stripping of the organic extract. The process has been tested on a FA generated in an integrated gasification with combined cycle (IGCC) process. The paper describes the designed 5 kg/h pilot plant and the tests performed on it. Under the operational conditions tested, approximately 50% of...
