What We Do

What is Battery Mineral Processing Plant Consulting?

Battery mineral processing plant consulting covers the full engineering and advisory lifecycle for facilities that convert raw critical minerals — lithium, graphite, cobalt, manganese, rare earths — into battery-grade materials ready for cell manufacturing.

A specialized battery mineral processing consultant bridges the gap between laboratory results and commercial production. This includes developing process flowsheets, sizing and specifying equipment, designing pilot plants, running techno-economic analyses (TEA), and guiding facilities through the critical TRL 4→9 scale-up stages where most projects stall or fail.

Unlike general chemical engineering consultants, battery mineral processing specialists understand the tight electrochemical performance specifications that OEMs demand — purity thresholds, particle morphology targets, electrochemical testing protocols — and design processing plants around meeting those specs consistently at scale.

The Scale-Up Gap We Solve

Lab results don't translate to pilot

Process parameters shift non-linearly at scale

Pilot plant yields don't hold at commercial scale

Equipment selection and process control become critical

OEM qualification fails at first submission

Specification gaps not caught until product testing

Delta3CoreTec's approach

Process engineering + OEM spec alignment + stage-gate discipline from day one

Industry Context

Why Battery Mineral Processing Plant Consulting Is Different

The global push to build non-Chinese battery mineral supply chains has created an urgent demand for experienced battery mineral processing plant consultants — engineers who understand not just chemistry and process engineering, but the specific performance standards that lithium-ion battery manufacturers require, the regulatory landscape for critical mineral projects in North America and Europe, and the funding mechanisms available to de-risk commercial-scale investment.

Most process engineering firms approach battery mineral processing plants the same way they would a conventional chemical plant: focus on throughput, yield, and CAPEX efficiency. This misses the fundamental challenge. A lithium processing plant consultant working on battery-grade lithium hydroxide must understand that the customer — a cathode manufacturer or battery cell producer — has specifications measured in parts-per-million impurities and will run months of electrochemical testing before qualifying a new supply source. Every process design decision must be made with that qualification endpoint in mind.

The same principle applies across the battery mineral supply chain. A graphite processing consultant developing a synthetic graphite anode facility needs to design processes capable of achieving 99.95%+ carbon purity, tightly controlled D50 particle size distributions, and specific tap density targets — not as secondary considerations, but as the primary design criteria that determine every furnace specification, purification chemistry choice, and spheronization equipment selection. Delta3CoreTec brings this battery-first lens to every mineral processing plant engagement.

We also understand that most battery mineral processing plant projects in the current environment require government funding support to reach commercial scale. The DOE Loan Programs Office, ARPA-E, and multiple IRA and BIL funding streams all require detailed technical packages that demonstrate process maturity, realistic TEA projections, and credible scale-up plans. Our consulting engagements are structured to generate the documentation and data these programs demand — not as a separate deliverable, but as a natural output of rigorous process development work.

Delta3CoreTec's principal consultant, former Urbix CTO Palash Bharadwaj, has led battery mineral processing plant projects from bench-scale feasibility through pilot plant commissioning and on to commercial scale — including a facility supported by a $125M DOE grant. This "spark to scale" track record across the complete project development lifecycle is what distinguishes genuinely specialized critical mineral processing plant consultants from generalist engineering firms entering the battery space.

Our Methodology

Spark to Scale: Processing Plant Development Roadmap

TRL 3–4

Feasibility & Flowsheet Development

Process concept development, feedstock characterization, preliminary flowsheet design, and order-of-magnitude TEA. Deliverables: process basis document, preliminary CAPEX/OPEX estimate, identification of critical process risks, and go/no-go recommendation for pilot investment.

TRL 5–6

Pilot Plant Design & Build

Detailed pilot plant engineering: P&IDs, equipment specification, vendor qualification, site layout, HAZOP, and commissioning plan. We design pilots specifically to answer the critical scale-up questions — not just demonstrate the process works, but to generate the engineering data needed for commercial plant design.

TRL 6–7

Process Optimization & OEM Qualification

DOE-driven optimization of critical process parameters, development of QA/QC systems, production of OEM qualification samples, and electrochemical performance validation. This stage generates the certified performance data that unlocks offtake agreements and secures the next round of financing.

TRL 8–9

Commercial Scale-Up Engineering

Development of the commercial plant technology package: scale-up factors, equipment sizing for 1,000–50,000 MT/year throughput, detailed TEA, project execution plan, and investor-ready technical documentation. Ongoing advisory support through construction, commissioning, and ramp-up.

Commercial Production & Continuous Improvement

Operational support, yield monitoring, predictive maintenance programs, and continuous process improvement. We remain engaged as a technical partner long after first production — because the gap between nameplate capacity and optimized commercial production is where lasting competitive advantage is built.

FAQ

Common Questions

Our core expertise covers battery anode materials (synthetic graphite, natural graphite, silicon-graphite composites), cathode precursor materials (pCAM, NMC, LFP precursors), lithium compounds (lithium carbonate, lithium hydroxide), rare earth element processing, and electrolyte components (LiPF₆). We are specifically focused on the materials that go into lithium-ion battery cells rather than upstream mining operations.
Early engagement — at the feasibility and pilot plant design stage — delivers the highest ROI. Poor process design decisions made at TRL 4–5 compound exponentially as projects scale. That said, we regularly engage with projects already in pilot operation that are struggling with yield, quality consistency, or OEM qualification — and have consistently achieved significant improvements through systematic process auditing and optimization.
Yes — this is a core part of our value proposition. We have direct experience developing the technical content for DOE grant applications for battery mineral processing projects, including the $125M DOE grant referenced above. We structure process development programs to generate exactly the performance data, TEA documentation, and technical narrative that these funding programs require. See our grant writing services page for more details.
Engagements vary widely based on project stage and scope. A feasibility study with preliminary TEA typically runs 6–10 weeks. Pilot plant design is a 3–6 month engagement. Ongoing process optimization support is structured as a retainer with defined deliverables. We begin every engagement with a structured scoping call to define objectives, deliverables, and timeline — book a call above to start that conversation.
Yes. We have supported battery mineral processing plant projects in North America, India, and Southeast Asia. Our consulting is location-agnostic for feasibility, flowsheet, and TEA work. For pilot plant design and commissioning support, we work with local engineering partners to provide on-ground presence where needed.
