Focus — lithium, recovered from spent lithium-ion black mass.
Azoth recovers the working metals from spent lithium-ion batteries — lithium, nickel, cobalt, manganese — and returns them to battery grade. The feedstock is assayed before the flowsheet is drawn; the chemistry of the cell decides the route, not the other way around.
The name comes from alchemy. Azoth was held to be the universal solvent — the agent that could dissolve any matter and return it, transmuted, to use. It also stood for the first and the last: the beginning that already contains its end.
We keep the ambition and leave the mysticism. The solvent is an acid. The transmutation is a flowsheet. What is not accounted for was not recycled — it was lost.
The metal a smelter loses to slag. Hydrometallurgy returns it — toward battery-grade carbonate or hydroxide.
Recovered as battery-grade sulphate — the volume metal of the modern cathode.
Recovered as sulphate. The highest-value unit inside most cells — the one most worth not losing.
Recovered with the nickel–cobalt cut, to cathode-precursor specification.
Black mass arrives without a birth certificate. We issue one — assay, lot code, chain of custody — before a single litre of acid is drawn. A cell has a first life and a last. Azoth is the passage from the last back to the first.
Recovery fails on assumptions, not on chemistry. Nothing advances until the gate before it closes.
No flowsheet is drawn until the black mass is measured. NMC, LFP, mixed — each chemistry dictates a different route. The feedstock decides the flowsheet, never the other way around.
Recovery is a mass balance before it is a yield. Every gram of lithium, nickel and cobalt is reconciled — in against out. A flowsheet that cannot conserve mass cannot be trusted to conserve capital.
Recovery routes are proven in coordination with national research institutions before capital is committed to steel.
Engineered inside the regulatory frame — Battery Waste Management Rules, EPR, hazardous-waste handling — from the first drawing, not retrofitted to it after the fact.
// These are the fixed numbers. The ones that move with the market — recovery rates, throughput, spreads — are published when the plant is, not before.
Recovered lithium, nickel and cobalt re-enter cathode production for traction cells.
The fastest-growing draw on lithium — and the demand recovered supply is built to meet.
India's cell makers face a requirement to use domestically recovered material. Azoth is built to be a qualified, non-PRC source of it.
The long tail of black mass — devices, tools, backup power — returned to grade.
Industry spends the cell. We return what it held.
Recovered lithium, nickel and cobalt are only as clean as the black mass they come from. Azoth sources from production scrap, qualified collectors and characterised imports — every lot assayed and coded before it enters the plant.
The facility rises in Gujarat, on the same industrial ground and the same hydrometallurgical discipline Satvikam applies to rare earths. Further particulars — location, footprint, capacity — will be published when the ground itself warrants them. Until then, the work continues without commentary.
Why hydrometallurgy — and why the acid, not the smelter, is where lithium survives.
The lithium lost to slag in pyrometallurgy, and what it costs to build a plant that keeps it.
From 2027, India's cell makers must use domestically recovered material. The demand is written into the rules, not the forecast.
If your work meets ours — spent cells, production scrap, black mass, refining, research or capital — write. State what you do plainly; we will do the same.
