Critical minerals expansion has a sulfate problem.
Too much of it
Production is scaling faster than the market can absorb.
Costly to get rid of
Disposal already runs up to USD $100 per tonne.
And the exit routes are closing
Stricter regulations, permits at risk, social license.
And it’s not just sodium sulfate -
gypsum and saline purges face the same dead end

You pay twice - buying reagents, then disposing of
the sulfate they become. Sycle closes the loop.
The only profitable technologies able to concentrate
sulfuric acid to 98% - electrolytic grade.
One platform,
two regeneration routes.
Backed by international patents.Electrochemical route
- Dedicated to sodium sulfate. From Na2SO4 to sulfuric acid and caustic soda.
- Lowest energy footprint in the industry.
- Based on proven technologies at scale.
Thermal route
- One thermal approach, two feeds: sodium sulfate or gypsum.
- Sodium sulfate yields sulfuric acid and caustic soda; gypsum yields sulfuric acid and lime
- 100% circular: no residue left behind.
One problem,
across the mineral industry
Wherever a sulfate meets a hydrometallurgical process, Sycle has a valorization route.
Whatever the route: turn your Sulfate by-product
stream into savings and simplify your procurement chain.
