India is one of the world's largest bauxite producers. NALCO, Hindalco, Vedanta, and ANRAK collectively process millions of tonnes annually. Gallium occurs in bauxite at 50–100 parts per million. India currently produces zero gallium.
BARC signed an MoU with NALCO in 2016 to develop extraction technology at Damanjodi, Odisha. A decade later, nothing commercial exists. In that same decade, gallium prices rose 800% and China — controlling ~80% of global supply — imposed export restrictions in 2023. Semiconductor fabs, LED manufacturers, and defence contractors in Europe, Japan, and the US are actively seeking non-Chinese supply. India has the ore, the refineries, and the chemistry research. What it lacks is a founder willing to close the loop.
"NALCO announced a 10-tonne facility in August 2025. Government timelines run slow. A nimble private operation can reach first revenue before NALCO's prototype is even tested."
Gallium is a trace dispersed metal — it hitchhikes inside aluminium-bearing minerals and concentrates in the caustic soda solution left after alumina precipitates out. Over multiple refining cycles it accumulates to 100–200 mg/L in the spent liquor. This is your feedstock — and refineries currently treat it as waste.
| Step | Process | Output | Difficulty |
|---|---|---|---|
| 1. Solvent Extraction | Organic solvent (Kelex 100 / D2EHPA) selectively binds gallium from alkaline liquor | Gallium-loaded organic phase | Medium |
| 2. Stripping | Acid back-extraction releases gallium into aqueous solution | Gallium sulphate solution | Low |
| 3. Electrolysis | Direct current deposits crude gallium at cathode | ~99% crude gallium | Low–Medium |
| 4. Zone Refining | Directional solidification removes trace impurities | 4N–6N purity gallium | Medium |
Kelex 100 is sensitive to exact pH and temperature. Different refineries produce liquor with different compositions. Your process chemistry co-founder must characterise your specific feedstock before any capital is deployed on pilot equipment. This is non-negotiable.
| Segment | Application | Purity | Access Path |
|---|---|---|---|
| Semiconductor fabs | GaAs wafers, RF chips, solar cells | 6N | Long-term supply contract |
| LED manufacturers | GaN substrate, power electronics | 5N–6N | Contract or spot |
| Defence (see §04) | AESA radar, EW, missiles, satellites | 5N+ | DRDO / BEL / HAL tender |
| Research institutions | Materials research, photovoltaics | 4N–5N | Direct purchase |
| Export (EU/Japan) | Supply chain diversification from China | 4N–6N | FIEO / Export Promotion Councils |
| Production Scale | Annual Revenue | Capex Required |
|---|---|---|
| 50 kg/year (pilot) | ₹87.5 lakh | ₹20 lakh |
| 500 kg/year (Series A) | ₹8.75 crore | ₹1.5–2 crore |
| 5 tonne/year (commercial) | ₹87.5 crore | ₹8–12 crore |
| 20 tonne/year (NALCO scale) | ₹350 crore | ₹40–60 crore |
Gallium is not just a commodity input. It is the foundational material for India's most critical defence systems. GaAs (Gallium Arsenide) and GaN (Gallium Nitride) are present in virtually every modern electronic warfare, radar, and precision guidance system.
India's defence modernisation program — the largest in its history — is creating demand for gallium-based components across every branch of the armed forces. And under current supply chains, every gram of gallium in Indian defence systems traces back to China.
"Every AESA radar India builds needs GaN power amplifiers. Every missile seeker needs GaAs chips. India is building an indigenous defence industry on a foundation of Chinese gallium. That is a strategic vulnerability hiding in plain sight."
Supplying gallium to India's defence ecosystem carries privileges unavailable in commercial markets:
Do not pursue defence contracts in Year 1. Qualification cycles take 12–18 months. Use commercial sales to establish track record and NABL-certified quality. Initiate DRDO/BEL conversations in Month 6, not Month 1. The relationship builds while you build the product.
The MoU for Bayer liquor access is the critical path regardless of how much capital you deploy. More money does not accelerate feedstock negotiations — it changes what you can build once you have access. Use the simulator below to understand the downstream impact of your initial investment.
Get 200–500 litres of spent liquor. Do not ask for more yet. Prove the process works with your specific feedstock.

The gallium extraction process is documented in open literature. Any competent chemical engineer can replicate it. Your competitive advantage is not the chemistry — it is feedstock access.
The refineries have direct incentive to sign. Spent liquor disposal is a cost and a regulatory burden. You are proposing to take it off their hands and share revenue. Frame it as waste-to-value, not as asking for a favour.
Primary MoU targets: NALCO Damanjodi (Odisha), Hindalco Muri (Jharkhand), ANRAK Visakhapatnam (Andhra Pradesh). ANRAK is newer with less entrenched waste handling — potentially most receptive.
No MoU = no business. Do not spend a single rupee on equipment before the feedstock agreement is signed. The MoU is not just access — it is your fundraising credibility, your barrier to replication, and your Series A story.
India's industrial policy is, for the first time, aligned with exactly what a gallium startup needs. The following advantages are not theoretical — they are active programs with allocated budgets.
This section does not hedge. Every risk listed below has the potential to end the venture if not actively managed. Read carefully before committing capital.
What happens: The refinery renegotiates terms, terminates the MoU, or a change in management deprioritises the arrangement. Without spent Bayer liquor, there is no gallium. The business stops entirely — equipment, team, and regulatory approvals all become worthless.
PSU refineries like NALCO operate under bureaucratic cycles. Project champions move on. New leadership may not honour informal agreements. Commercial pressure from the refinery's own operations takes priority over waste stream arrangements.
Secure MoUs with minimum two refineries. Include revenue-share incentives — give them a reason to keep the agreement active. Pursue ANRAK (private, more commercially agile) alongside NALCO. Never deploy pilot capex before MoU is signed and legally reviewed.
What happens: Solvent extraction using organic chemicals requires Hazardous Waste Authorisation from KSPCB (Karnataka State Pollution Control Board). If this is delayed, you cannot legally operate your pilot plant. Equipment sits idle. Runway burns. Team loses momentum.
KSPCB processing times are unpredictable. Chemical procurement under PESO (Petroleum and Explosives Safety Organisation) for solvent storage adds another layer. Both are bureaucratic and sequential.
File on Day 1 — not after the lab is built. Hire a Karnataka-specific environmental compliance consultant (₹50–80K, worth every rupee). Use the 3–6 month wait for bench-scale validation in a lab that operates under less stringent approvals. Never build the pilot plant before authorisation is in hand.
What happens: If geopolitical conditions change and China resumes full gallium exports, prices could fall from $2,100/kg toward pre-2023 levels of $300–400/kg. At those prices, a small Indian operation with higher unit costs may struggle to compete.
China's export restrictions are a policy tool, not a permanent structural change. US-China trade negotiations, WTO challenges, or a change in Beijing's strategic calculus could reverse them.
Secure long-term offtake agreements before scaling — lock in prices above break-even. At pilot scale (₹20L capex), break-even is below $600/kg. Hedge by moving up the value chain into gallium compounds (GaN precursors, TMGa) where margins are insulated from spot price volatility.
What happens: Your process chemistry co-founder holds the technical knowledge that makes the plant work. If they leave — for a better offer, personal reasons, or equity disputes — operations may stop entirely until a replacement is found and trained.
Deep chemistry expertise is rare and well-compensated. A 4-person startup cannot match what a large corporate or foreign competitor might offer. Equity disputes are common at pre-revenue stage when expectations diverge.
Document everything obsessively from Day 1. All process parameters, yields, troubleshooting decisions in written SOPs. Vest equity over 3 years with a 1-year cliff. Invest in cross-training a second operator by Month 6. The IP must live in systems, not in one person's head.
What happens: Semiconductor and defence buyers require 12–18 months of qualification testing before committing to supply contracts. You may reach production capability before you have a paying customer, draining working capital.
High-purity material qualification is rigorous. Buyers run extensive purity verification, batch consistency testing, and supply reliability assessments before signing contracts. This timeline cannot be compressed.
Start buyer conversations in Month 1, not Month 9. Research institutions and smaller LED manufacturers have faster qualification cycles. Use first production runs as free samples for qualification testing — they buy time. Target at least one confirmed letter of intent before scaling to pilot phase.
What happens: Spent Bayer liquor composition varies depending on the ore source, process conditions, and refinery cycle stage. A process optimised on one batch may underperform on the next, reducing yield and increasing solvent consumption.
Bauxite ore composition in Odisha and Jharkhand is not homogeneous. Seasonal variation in ore sourcing, refinery maintenance cycles, and process chemistry changes at the refinery all affect the liquor you receive.
Characterise every incoming batch before processing. Build a process monitoring protocol into standard operations from Day 1. Maintain a buffer of 2–3 weeks' feedstock supply to allow for process adjustment between batches.
Business development, MoU negotiations, government scheme navigation, investor relations. Must operate comfortably at the intersection of industrial manufacturing, policy, and deep tech. Prior experience in mining, chemicals, or strategic commodities is an advantage — not a requirement.
This is the critical hire. A PhD with direct experience in solvent extraction of gallium from alkaline solutions — someone who has worked on the NALCO-BARC project or equivalent IIT research. Offer 20–30% equity. Without this person, you are guessing at process parameters they have already solved on government grants.
KSPCB, CPCB, PESO (solvent storage), Factory Inspectorate, and DGFT for export. A Karnataka-based environmental and industrial compliance consultant at ₹50–80K is worth months of delays avoided.
