Photography Auxillary Processes TRIZ Cases
- Electrowinning Cell Flow Path Layout for Even Metal Deposition
Impermeable anodes and secured cathodes create a tortuous flow path that prevents clogging, supports continuous operation, and evens metal deposition.
- Rare Earth Electrorecovery Using Ionic Liquid Coordination Chemistry
Ionic liquids plus polar protic solvents enable low-temperature electrorecovery of rare earth elements with higher purity and fewer hazardous byproducts.
- Spiral Lithium Brine Filter Cartridge With Distributed Current Contacts
Multiple edge contacts in a spiral brine-permeable cartridge even out charge and lithium uptake, improving recovery and limiting corrosion.
- Oxidative Heap Leaching for Refractory Copper Sulfide Ores
Sequential low-flow acid, nitrate, and oxidant irrigation transforms chalcopyrite heaps to boost copper recovery with lower water use and NOx emissions.
- Spiral Lithium Brine Filter Cartridge With Distributed Current Contacts
Multiple edge contacts in a spiral brine filter cartridge even out current paths and lithium uptake, improving recovery capacity during extraction.
- Phytomining of Ultramafic Rock for Carbon-Negative Metal Recovery
Hyperaccumulator plants and enhanced weathering turn ultramafic rock into a carbon sink while recovering nickel and cobalt from biomass.
- Membrane-Stacked Electrolytic Bath for Faster Lithium Extraction
Stacked membrane compartments cut electrode spacing and improve brine distribution, boosting lithium extraction while lowering resistance and leakage.
- Electrochemical Metal Extraction for Selective Recovery From Acidic Streams
An electrochemical reactor with alternating silicon electrodes selectively recovers metals from acidic streams without precipitation or thermal steps.
- Imprinted MOF Filling Material for Selective Copper Electrolyte Purification
Selective imprinted MOF adsorption removes additive decomposition products from copper electrolyte, improving foil ductility and surface smoothness.
