Technology · BEST™

Battery-grade nickel without the autoclave.

BEST™ extracts nickel selectively at atmospheric pressure, without autoclaves — an independent, non-HPAL route to Class 1 nickel, designed to recover its residues instead of storing toxic tailings.

Readiness
TRL 6
Temperature
Up to 95 °C
Pressure
~1 bar

The problem

One route. One country. One failure point.

Battery-grade nickel is concentrated, energy-intensive to produce, and dominated by heat- and pressure-heavy incumbents that leave toxic waste behind.

01

Single point of failure

Indonesia supplies roughly 60% of the world's mined nickel, and refining is concentrated in even fewer hands — leaving the global battery supply chain dependent on a narrow set of sources for Class 1 nickel.

02

Heat- and pressure-intensive incumbents

HPAL relies on high-temperature, high-pressure autoclaves — energy-hungry, capital-heavy, and operationally demanding to run safely.

03

Toxic, unmanaged waste

Conventional routes generate large volumes of acidic tailings and toxic by-products that require costly long-term containment.

The product chain

From nickel ore to the battery cell

  1. 01

    Nickel ore

    Lateritic nickel ore under a long-term, non-binding supply MoU.

  2. 02

    MHP

    Mixed hydroxide precipitate — an intermediate battery feedstock concentrating nickel for refining.

  3. 03

    Nickel sulfate

    Battery-grade nickel sulfate, the precursor input for cathode active material.

  4. 04

    Cathode → cell

    Refined nickel units flow into cathode and cell manufacturing — with Class 1 metal also serving aerospace and energy superalloys.

Solid waste · BANIQL BEST™

Recoverable

Solid residues designed for recovery as agricultural fertilizer and magnesium products rather than permanent tailings.

Solid waste · Atmospheric leaching

High volume

Large volumes of residue that must be neutralized to mitigate environmental damage.

Solid waste · HPAL

High volume

Large volumes of acidic tailings requiring long-term management.

~70–80% less energy · selective nickel leaching with iron rejection · 3× nickel concentration · atmospheric leach at up to 95 °C, ~1 bar

Recoverable by-products

Designed to be saleable, not stored.

The BEST™ process is designed to turn what conventional routes discard as hazardous waste into useful materials.

01

Agricultural fertilizer

Solid residue recovered as ammonium sulfate (~21% N) — targeted as a saleable agricultural fertilizer, currently in field trials growing corn.

02

Magnesium products

Magnesium-bearing streams recovered as magnesium hydroxide, Mg(OH)₂ — a targeted secondary revenue stream, at lab-prototype stage.

Proven, not theoretical

Validated today, positioned for the deficit ahead.

Class 1 nickel is projected to flip to structural deficit around 2028–2030 (Benchmark Minerals, Fastmarkets). BANIQL pairs a working process with a long-term ore-supply MoU and a product evaluated by potential customers.

01

Validated product

Over 1,000 kg of battery-grade MHP produced and evaluated by potential customers in Korea, Japan, Taiwan, and the US.

02

Pre-pilot operating

TRL 6 process running in Indonesia since February 2025 at over 100 kg/day of ore, with long-term ore supply under a non-binding MoU.

03

Commercial pull

A signed, non-binding offtake LOI with a Korean customer — estimated at US$16.5–21M — underpins demand for BANIQL nickel units.
