Process Efficiency Improvement TRIZ Cases
- Molten Steel Al Deoxidation Under Vacuum With Controlled Heat Balance
Controlling the heat balance during Al addition in vacuum refining cuts evaporation loss, improves Al yield, and stabilizes steel composition.
- Oxidative Bioleaching Pretreatment for Faster Base Metal Recovery
Acidic sulfate agglomeration with nitrate or nitrite pre-oxidizes ore, speeding copper and nickel bioleaching without suppressing microbes.
- Steel Smelting Sequence to Reduce MnS Inclusions
Adding rare earths and sulfur before manganese forms fine sulphides that suppress MnS inclusions and improve steel workpiece reliability.
- Oxalic Acid REE Extraction from Loaded Organic Phase
Oxalic acid precipitates rare earths from a loaded organic phase, improving REE concentration, purity, and acid use in AMD recovery.
- Zinc Ferrite Decomposition in High-Alkali Boiling Recovery
Maintaining a high-concentration alkali at its boiling point decomposes zinc ferrite with lower energy use and simpler zinc recovery.
- Cyclone Separation of Coal Refuse for Rare Earth Recovery
A staged cyclone process concentrates rare earths, lithium, and titanium from fine coal refuse while reducing clogging, energy use, and water waste.
- Rare Earth Oxide Reduction Using Induction Heating and Cold Traps
Inductive heating above 2000 K and cold-trap water removal drive rare earth oxide reduction toward cost-effective elemental extraction.
- Iridium Oxide Recovery via Reduction-Assisted Mild Acid Dissolution
A reduction step converts corrosion-resistant iridium oxides into more soluble species, enabling faster recovery in mild acids with lower energy use.
- Beryllium Oxide Dissolution Using Dielectric Heating in Acid
Dielectric heating dissolves beryllium oxide in acidic solution without energy-intensive sintering or melting, cutting process energy and cost.
- Molten Steel Secondary Refining with CaO-Al2O3 Slag for Fast Denitrification
Controlled Al and CaO addition forms a CaO-Al2O3 slag that enables fast denitrification and desulfurization while limiting erosion and slag overflow.
- PARIS Zinc Finger Domain for Selective Cobalt Ion Recovery
A PARIS zinc finger domain expressed in E. coli selectively binds cobalt ions, improving recovery specificity from industrial waste.
