Patented technology
An independent, non-HPAL route to Class 1 nickel, protected by a granted US patent and international (PCT) applications.
Route to Class 1 nickel· TRL 5 · US HQ
A new path to
critical-minerals security.
Indonesia supplies most of the world's mined nickel, and refining is concentrated in even fewer hands. BANIQL is a US-headquartered company building an independent, non-HPAL route, proven at pre-pilot scale in Indonesia and operating continuously since 2025, with battery-grade product evaluated by potential customers and signed offtake LOIs in Asia and the US.

BANIQL / BEST™: atmospheric leaching at low temperature, with no autoclaves. Bars are illustrative, relative to HPAL.
The approach
A cleaner route to battery-grade nickel
01
Selective, atmospheric chemistry
Our process selectively leaches nickel while rejecting iron, and runs at atmospheric pressure, unlike HPAL's high-temperature, high-pressure autoclaves. It upgrades nickel several-fold on the way to product.
02
Lower energy, circular by-products
The route uses far less energy than HPAL, and is designed with circularity in mind: its residues become agricultural fertilizer and magnesium products rather than permanent tailings.
Why it matters
Nickel demand surges. Supply stays concentrated.
Demand is set to multiply over the next decade for EV batteries, superalloys for spacecraft and jet engines, and gas turbines powering AI data centers, while most mined supply sits in one country and Class 1 nickel heads into structural deficit around 2028–2030.
02
Validated product
Battery-grade MHP produced at our pre-pilot facility and evaluated by potential customers across Asia and the US.
03
Feedstock line of sight
A long-term, non-binding ore-supply MoU in Indonesia anchors feedstock for scale-up, from nickel ore through to nickel sulfate.
04
Production capabilities
A pre-pilot facility in continuous operation in Indonesia since 2025, processing ore at atmospheric pressure.
05
Commercial traction
Signed, non-binding offtake LOIs with customers in Asia and the US, validating demand for new, diversified sources of Class 1 nickel.
From pre-pilot to commercial
Modular refineries, sited next to the ore.
The same atmospheric-pressure chemistry scales into modular commercial refineries, free of the heavy autoclave footprint that defines HPAL.
