Recovering Materials TRIZ Cases
- Ionic Liquid Extraction for Selective Iron Removal
Phosphonium salt ionic liquids selectively extract Fe(III) ions from aqueous feedstocks via liquid-liquid transfer.
- Organic Amine Lixiviant for Selective Alkaline Earth Metal Recovery
Organic amine cation complexes selectively solubilize metal hydroxides via ion exchange, resolving environmental hazards from traditional lixiviants.
- Rocking Receptacle for Aluminum Dross Metal Recovery
A rocking receptacle tilts to pour molten aluminum from dross through angled outlets.
- Oxidative Leaching of Metal Sulfides with Ceramic Grinding Media
Ceramic grinding media disrupt metal sulfide crystal lattices to accelerate oxidative leaching kinetics, reducing energy consumption and reagent requirements.
