Lattice Graph × ReElement Technologies

Lattice Graph operates a computational materials-discovery platform built around a knowledge graph that spans millions of compositions, connecting elemental identity to structure, thermodynamic properties, synthesis routes, and the patent landscape in a single governed graph. For a chromatographic refiner like ReElement, that means every candidate sorbent or leach chemistry arrives pre-connected to its mechanistic provenance, supporting experimental anchors, and the prior-art neighborhood that determines freedom to operate. Rather than returning a ranked list of ligands, the platform lets ReElement trace why a particular catecholate or phosphonate-amide architecture is selective for dysprosium over neodymium, at which pH window, and how that claim intersects with incumbent solvent-extraction art. Validation runs across multiple independent physics engines simultaneously. Machine-learning interatomic potentials, including MACE and CHGNet, are paired with density-functional-theory calculations to reach consensus on phonon stability, formation energy, and selectivity-governing binding geometry before any synthesis decision is made. A candidate sorbent architecture does not graduate from the knowledge graph to a recommended embodiment unless independent methods agree. For separation chemistry, where a small geometric or electronic difference determines whether a resin pulls Dy over Tb or Ge over Zn, this multi-engine consensus is the difference between a selectivity prediction with a known confidence interval and an uncorroborated number from a single model. The platform also holds a large labeled atlas of negative results, failed sorbent designs, lixiviant conditions, and process sequences that did not work, most of which never appear in the public literature. For a refiner evaluating new feed chemistries or stationary-phase architectures, this negatives moat is an asymmetric advantage: it encodes which ligand families, pH windows, and solvent systems are known dead ends, so ReElement does not spend pilot-plant time rediscovering them. That library, combined with freedom-to-operate screening across more than 300,000 materials patents, means a shortlist of candidates arrives with both its chemistry and its IP defensibility already characterized.

ReElement Technologies has built a chromatographic refining business around a simple but hard-to-replicate proposition: turn mixed, often dirty feedstock into traceable, qualified rare-earth oxides and battery-metal salts using stationary-phase separation rather than long solvent-extraction cascades. The differentiation lives entirely in the ligand chemistry, the separation sequence, and the ability to defend that chemistry against incumbent solvent-extraction patents. Lattice Graph addresses all three in a single engagement: a library of selective recovery chemistries with freedom-to-operate already characterized, layered on top of feed-intelligence APIs that map which waste streams are realistically convertible to which separated products. The strategic pressure ReElement faces in 2026 is well-defined. Heavy rare-earth supply (dysprosium, terbium) is constrained by Chinese export controls on adjacent critical minerals including gallium and germanium. The EU Battery Regulation creates a compliance timeline for recycled-content traceability that rewards refiners with an auditable, documented feed thesis. And the competitive moat of a domestic chromatographic refiner narrows if a well-funded entrant can license similar ligand families from the public literature. The combination of a curated, validated separation-chemistry portfolio with defensible IP and an API-layer feed map is the precise toolkit for widening both the revenue base and the defensibility of ReElement's refining lines. Lattice Graph's fit here is not analogical, it is direct. The critical-mineral recovery and recycling separations portfolio was generated specifically to address the selectivity gaps and IP whitespace that matter for chromatographic critical-mineral refining. The sorbent and process assets map one-to-one onto ReElement's existing lines, from rare-earth pair splits to battery black-mass leaching to germanium recovery from zinc-refinery residue. The data and knowledge-graph layer then gives the feed-thesis and freedom-to-operate infrastructure that turns those individual assets into a coherent, scalable refining strategy.

ReElement's core rare-earth chromatographic lines map onto the critical-mineral recovery and recycling separations portfolio with unusual directness. That portfolio contains selective sorbent architectures and process sequences for the specific adjacent-pair and heavy-rare-earth splits that define refining economics: dysprosium and terbium recovery from NdFeB magnet leachate, rare-earth-pair differential-precipitation polishing across the lanthanide series, and gallium extraction from high-alkalinity alumina-refinery liquors. For a company whose differentiation is the stationary-phase chemistry and the sequence in which elements elute, this is not a collection of adjacent technologies but a set of candidate deployments for existing refining lines, each arriving with multi-engine stability anchors and freedom-to-operate analysis already completed. The battery-material and recycled-feedstock processing line maps onto the chloride-free deep-eutectic-solvent battery recycling platform within the same portfolio, which provides a staged lithium-first then nickel-cobalt-manganese leach of cathode black mass without the chloride chemistry that drives equipment corrosion and complicates EU recycled-content reporting. That platform functions as a front-end leach for ReElement's existing separation columns rather than competing with them, widening the recycled-feed window into end-of-life battery material at a compliance-friendly process chemistry. Beyond rare earths and batteries, the germanium sorbent and universal chelating-resin genus within the portfolio extend ReElement's addressable feed to zinc-refinery residue and copper-smelter byproducts, recovering germanium, antimony, gallium, and a roster of critical oxocations from acidic industrial streams. The integrated system-level flowsheet asset in the portfolio frames these individual chemistries as a coordinated recovery cascade rather than disconnected point solutions, which fits ReElement's modular, replicable line architecture. For a refiner building out multiple lines across locations, having a unified sorbent genus and a system-level flowsheet claim rather than a collection of bespoke per-element designs substantially reduces the complexity and cost of adding new feedstocks.

ReElement's technical and commercial teams would work primarily in three areas of the platform. The supply and conversion-route workflow lets the feed-sourcing and business-development team model feedstock-to-separated-product chains visually, attaching deposit concentration and criticality data to each stream and stress-testing the feed thesis against supply-risk forecasts for specific elements. Outputs from that workflow feed directly into commercial materials: per-element supply-risk summaries and conversion-route maps that can be included in offtake proposals or lender diligence packages without manual reconstruction from multiple sources. On the chemistry and IP side, the knowledge-graph explorer lets ReElement's R&D team traverse from a target element to candidate sorbent architectures, through the patents and synthesis recipes around each architecture, with trust and disagreement scoring flagging which selectivity or stability numbers are corroborated across multiple computational methods versus resting on a single source. The batch screening workflow runs a slate of candidate stationary phases or leach conditions against the negatives moat and the patent landscape in a single pass, surfacing what is known to fail alongside what is clear to operate in ReElement's specific pH and feed-chemistry windows. The dossier and readiness view then summarizes the validation state of each asset, which is the natural input for a milestone-gated license structure where royalty terms are tied to bench results in ReElement's actual feed.

A sensible first engagement is a time-boxed validation and feed-intelligence sprint, typically scoped to six to eight weeks, focused on the two or three highest-priority assets for ReElement's current refining lines and one target feed region. That sprint delivers a validated shortlist of sorbent architectures and process parameters for each target element, a freedom-to-operate summary confirming the disclosed IP carve-outs hold in ReElement's actual operating windows, and a feed-thesis map connecting the recoverable elements to supply risk and conversion economics for one identified waste stream. The output is designed to function as the technical and commercial foundation for a license negotiation, not as a standalone report. If the bench results from that sprint confirm the selectivity and process targets, the natural conversion is a bundle license covering the relevant separation assets from the critical-mineral recovery and recycling separations portfolio, structured with milestone payments tied to agreed laboratory targets in ReElement's feed and a running royalty on separated product. Alongside the IP, an annual subscription to the supply, deposit, and remediation intelligence products with knowledge-graph and freedom-to-operate access provides the continuing feed-strategy and IP-monitoring layer that a scaling refiner needs as it adds lines and feed streams. Pricing for the data subscription and the asset license should be scoped to ReElement's number of active refining lines and target elements; the validation sprint is the appropriate first step to establish that scope before committing to license terms.
