Benefits
Benefits for industry partners
- Improves material efficiency
- Creates new industrial value from waste streams
- Competitive and economic cost structure
- Modular design enables rapid deployment
- Energy efficient
- Positive environmental impact
Specific benefits for:
Turn polymetallic ores and mine tailings into recoverable metals: at your site, not a centralized refinery.
- Unlock value from feedstocks previously uneconomical to process
- Recover critical minerals on-site: new revenue from existing operations
- Zero waste discharge: closed-loop reagent recycling eliminates process waste and shortens permitting timeframe
- Modular deployment scales with existing infrastructure: no refinery buildout required
Turn slag from a disposal cost into recoverable metals: at your site, not a centralized refinery.
- Transform EAF and BOF slag from disposal liability into recoverable manganese, cobalt, aluminum, and iron
- Zero waste discharge: closed-loop reagent recycling eliminates process waste and shortens permitting timeframe
- Integrates with existing slag handling infrastructure: no refinery buildout required
- Eliminate long-term stockpile liability and environmental compliance costs
Turn cement making residues and CO₂ into sustainable construction materials: at your site, not a centralized plant.
- Permanently store CO₂ as solid carbonates: a drop-in substitute for virgin limestone
- Recover silica from mineral processing residues as a supplementary cementitious material
- Zero waste discharge: closed-loop reagent recycling eliminates process waste and shortens permitting timeframe
- Modular deployment integrates with existing kiln infrastructure: no major capital buildout required

The problem we’re addressing
The US faces a critical minerals shortage,
while valuable materials go unused
The US depends on foreign sources for the critical minerals that power electric vehicles, defense systems, and advanced manufacturing - while billions of tons of domestic ore, slag, and industrial residues sit unprocessed.
Supply crisis
100%
US imports of manganese, majority of magnesium and other critical minerals
Wasted resource
14Bt/yr
Mine tailings and residues generated globally: rich in critical minerals, unprocessed
Unlocked value
$3.4T
Estimated value of critical minerals locked in global industrial waste streams
Conventional hydrometallurgical processing requires centralized, capital-intensive refineries that make polymetallic, distributed feedstocks uneconomical to process.
Leaving domestic critical mineral supply chains dangerously exposed, while valuable materials are landfilled or stockpiled as liabilities.
Our tech
Closes the materials cycle
Our feedstock can include a broad range of industrial materials or residues such as polymetallic ores,
mine tailings, ferrous slag, aluminum dross, and cement making residues.
Our processes turn them into valuable resources.

TM pendingThe only closed-loop electrochemical platform purpose-built for polymetallic industrial feedstocks
- Polymetallic Recovery: Recovers nickel, cobalt, magnesium, and manganese from ores, slag, and industrial residues conventional processing cannot economically handle
- Closed-loop Process: Generates and recycles its own acids and bases in-situ with zero chemical inputs, zero waste discharge
- Modular Architecture: Drives faster deployments compared to conventional hydrometallurgical processing
- Proprietary IP: Protected by a portfolio of patent applications
TM pendingTurning alkaline residues and CO₂ into a revenue-generating construction material
- Permanent Mineralization: Convert CO₂ into stable solid carbonates without reversal or leakage
- Cuts costs and increases revenue: Converts cement making residues from a disposal liability into a saleable construction material
- Drop-in construction material: Substitute for virgin limestone in cement and concrete production
- Customer-validated: Four of the world's largest cement producers are evaluating LithoLock for commercial deployment
