Process Efficiency Improvement TRIZ Cases

Airlift flow and submerged reagent injection support consistent sulphur removal while reducing stirring energy and process disturbance.

A 180–240°C sulfide stage followed by high-temperature carbon oxidation reduces residence time and improves precious-metal recovery.

Thermal, acid, and saline leaching separates zinc, copper, silver, lead, and iron oxide from jarosite residues.

Carbonate or bicarbonate raises pH to release uranium while strong acid resin retains iron contamination.

Selective reduction and a super-gravity reactor separate metallic iron from niobium-rich slag for lower-loss niobite utilization.

This case uses controlled CaO, SiO2, and Al2O3 flux ratios to reduce precious metal loss during phase separation.

This case addresses toxic, complex gold extraction with anion-doped polymers that adsorb and electrolessly reduce gold and silver ions.

This case uses mild pyrolysis and solvent extraction to keep REEs accessible, enabling weak-acid recovery from coal feedstocks.

Cased wells inject pressurized reagent fluids to open flow paths, drain pooled liquid, and strengthen heap stability.

This redox process uses excess metal compound feed to improve conversion while limiting unreacted reductant in the composite.

A cement and retarder coating improves cyanide utilization in gold ore extraction while extending slurry thickening time.

The composition uses controlled Si, Mn, Cu, P, and S ratios to improve chloride resistance and mechanical properties without Cr, Ni, or Mo.
