Immobilization of heavy metals (Cd, Ni or Pb) using aluminate geopolymers
(Elsevier, 2018-09)
In the present study, a waste aluminate solution from the anodizing industry was used to synthesize coal fly ash- and blast furnace slag-based geopolymers as metal-immobilizing matrixes. Different alkali-activating agents ...

Demonstration Plant Equipment Design and Scale-Up from Pilot Plant of a Leaching and Solvent Extraction Process
(MDPI, 2015-05-28)
Germanium recovery from coal fly ash by hydrometallurgical procedures was studied at the pilot scale (5 kg of fly ash/h). Results were used to design the equipment of a demonstration-sized plant (200 kg of fly ash/h). ...
