So I asked AI:
“Does Mkango’s sintering process help in the MP vs USAR situation?”
Yes, but for different reasons:
Where Mkango sits on sintering vs MP/USAR:
| Company | Core process |
| **MP Materials** | Mining → separation → NdPr oxide → sends to China/Japan for sintering. Just built Texas 10X plant to sinter in US. |
| **USA Rare Earth** | Mining Round Top + Stillwater OK plant for sintered magnets. Accused by MP of stealing sintering/grain boundary diffusion tech. |
| **Mkango/HyProMag + Maginito** | Recycling scrap via HPMS → NdFeB alloy powder → **sintering to finished magnets** in UK plant + planned Texas plant. No mining, no MP/USAR patent fight. |
Why your sintering helps with US funding right now:
US gap is sintering, not mining: US can mine at Mountain Pass. But 90%+ of global magnet sintering is in China. DoD wants sintering capacity on US soil ASAP. MP’s 10X plant is one answer. HyProMag USA Texas Hub is the other. MP/USAR lawsuit slows both their sintering timelines.
Recycled feedstock = different sintering challenge: Virgin sintering from oxide needs grain boundary diffusion for heavy REEs. Recycled HPMS powder is already alloy + closer to magnet composition. Sintering recycled powder uses less Dy/Tb and skips the “grain boundary” IP that MP + USAR are fighting over. US govt loves “less HREE dependent” tech.
Speed to magnets: MP/USAR are arguing over mining → oxide → sintering chain. Your sintering takes recycled alloy powder → magnet in fewer steps. That’s why Texas Hub targets H1 2027 while MP 10X is 2028. DoD pays premium for speed.
MP vs USAR lawsuit makes your sintering more valuable:
MP alleges USAR stole sintering/grain boundary diffusion formulations. If MP wins, USAR’s sintering plant gets delayed. If USAR wins, MP looks weaker. Either way, DoD gets nervous about relying on 2 companies in court.
Mkango can walk in and say: “Our sintering process is for recycled powder, not virgin ore. No MP/USAR patents involved. Texas plant leased, EXIM $92M LOI in hand, feedstock contracted. Fund us as the backup sintering option.”
Catch with sintering:
Sintering recycled magnets still needs final alloying + pressing + coating. Quality/grade must hit EV/drone specs. That’s why Mkango hired PegasusTSI + BBA for EPCM. If you prove Texas sintering hits 50MGOe grades, US funding gets much easier.
Bottom line: Your magnet sintering is exactly what US wants right now — domestic capacity, fast, not tied to MP/USAR mining/IP fight. The lawsuit makes “recycled sintering in Texas” a much cleaner pitch to DoD/DOE/EXIM than “another virgin magnet plant”.
If Mkango’s Texas sintering process is locked and de-risked, this MP/USAR drama is perfect timing to push for DoD Title III money.
Is Mkango’s Texas sintering targeting EV-grade N52 or more defense-grade N35SH/N42SH? Defense specs unlock more DoD funding.
