Advanced Metallurgy & Circular Materials
Industrial residue into critical metal, alongside run-of-mine ore into saleable concentrate — backed by a technology consortium for titanium, gallium, hafnium and zirconium.
Technology Consortium
Titanium, Gallium, Hafnium and Zirconium
KGS has signed a consortium agreement with JSC Titanium Institute, Ukraine and Vega Instrumentation, USA to carry out engineering for titanium, gallium, hafnium, zirconium and other critical-metal extractive metallurgy technologies.
- Titanium slag
- Titanium metal
- Gallium
- Hafnium

Register
Two Registers, One Discipline
KGS works both ends of the material chain — run-of-mine ore into saleable concentrate, industrial residue into critical metal. Gold, vanadium, and zinc appear in both registers on purpose: proof KGS recovers each from virgin ore and from residue alike.
