Crystallization
Silver is the best electrical and thermal conductor of any metal and has no substitute at high current density in a small envelope — busbar plating, high-current contacts, connectors, brazing and solder.
Technology brief
Silver is the best electrical and thermal conductor of any metal and has no substitute at high current density in a small envelope — busbar plating, high-current contacts, connectors, brazing and solder.
The challenge
Primary use cases: silver recovery from acid mine drainage of lead-zinc and copper mines; plating and electronics rinse and etching liquors; photoprocessing and medical X-ray fixers; copper anode slime liquors and refinery effluent. Fifth stream (2026-08): end-of-life photovoltaic module recycling — leach liquors, barren solutions after electrowinning, flotation process water. See ARBOK PV-Silver.
Outputs/uses: silver concentrate (with the copper and lead of the same stream) to the operator's existing chemistry; clean water; dry ballast fractions.
Scale: container-class; single unit to cascades. Fixer is a low-volume, high-tenor stream — collection and central treatment, not on-site 200 m³/day.
ARBOK solution
Silver is the best electrical and thermal conductor of any metal and has no substitute at high current density in a small envelope — busbar plating, high-current contacts, connectors, brazing and solder. That is the specification of modern high-density computing: an AI rack dissipates tens of kilowatts across thousands of joints. World IT power capacity went from 0.93 GW (2000) to nearly 50 GW (2025); US data-centre construction is up 85% in two years. Industrial silver demand went from 588.7 Moz (2015) to a record 680.5 Moz (2024).
Supply cannot answer: only 27.8% of output comes from primary silver mines, 29.4% is a by-product of lead and zinc, the rest of copper and gold — three quarters of supply is set by the plan for other metals. Mexico 27.3%, China 14.3%, Peru 13.4%. The market has been in deficit six consecutive years; 2026 is forecast at 215 Moz, about a quarter of annual mine output, and it is closed from above-ground stocks — exchange inventories are down to 136 Moz.
The distinguishing mechanism of this case: silver is the only precious metal that dissolves by itself. Gold and the PGMs must be forced into solution with aggressive chemistry; silver enters solution spontaneously in the media industry already operates in — nitrate and cyanide baths, thiosulphate fixers, acid mine drainage, etching liquors. The share of silver lost with water is therefore structurally larger than for any other precious metal, and it is lost by the chemistry of the element rather than by poor practice.

Whole stream concentrated by deep vacuum at ambient temperature; only water evaporates and condenses as clean product. No membranes, electrodes or reagents in the core; zero liquid tails. Cost per m³ set by phase-change energy, independent of concentration — decisive here because silver losses are spread across streams from sub-mg/L drainage to hundred-mg/L rinse, in matrices (cyanide, thiosulphate, nitrate, low-pH sulphate) that foul sorbents and consume precipitants.
Market and application
Six years of deficit met from a finite stock of already-mined metal, with industrial silver leaving circulation permanently as micron films. The recoverable increment inside existing water circuits is the cheapest incremental supply available — the metal is already mined, milled and dissolved.
Reference: one module, 200 m³/day, 73,000 m³/year, at $2,040/kg Ag.
Total: up to $16 M/year from one container on the richest stream described.
Wording rule for all external use: quote the total as "up to $16 M", never as a "$0.2–16 M" range. A two-order spread reads as not knowing your own economics.

Scale: container-class; single unit to cascades. Fixer is a low-volume, high-tenor stream — collection and central treatment, not on-site 200 m³/day.
Steps: stream assay → finishing configuration → install on the effluent circuit → commissioning. Purchase (payback 5–8 years) or BOOM (PAY&GO + off-take at a discount to the exchange price).
Co-locates with plating and PCB lines, copper and lead-zinc refineries, mine water treatment plants; central collection schemes for fixer.

Platform base: deep vacuum at ambient temperature; water return up to 100%; high-recuperation condensation circuit; container module 200 m³/day = 73,000 m³/year; service life 15–20 years.
Resource: $63.5/oz (mid-2026), +66% y/y ≈ $2,040/kg. Deficit 2026 forecast 215 Moz, sixth consecutive year. Exchange stocks 136 Moz. Mine output 819.7 Moz; scrap 193.9 Moz (12-year high). Industrial demand 680.5 Moz, >50% of total. PV 77.6 Moz (2015) → 232 Moz (2024); electrical & electronics 246.7 → 254 Moz over the same decade.
Feed concentrations: AMD ≤0.1 mg/L; plating/electronics rinse 10–100 mg/L; spent thiosulphate fixer g/L; copper refinery liquors 0.5–5 mg/L. Assay per stream.
Platform vacuum separation + dry ballast extraction + silver finishing (cementation, ion exchange or electrowinning depending on matrix). 200 m³/day standard module, parallel installation to match stream volume.
Technical: takes the dissolved fraction that classical circuits structurally lose; indifferent to cyanide/thiosulphate/nitrate matrices; co-recovers copper and lead.
Economic: cost per m³ independent of concentration; on statutory-treatment streams the displaced lime, sludge and reagents carry the project and the silver is upside.
Environmental: ZWD; 100% water return; silver is toxic to aquatic biota and permit limits are tight (commonly 0.1–1 mg/L), silver-bearing sludge often classified hazardous — both obligations removed.
Strategic: the only increment of silver supply whose quantity is set by a decision, not by the mine plan for lead and copper.

Platform TRL 9. Silver finishing uses proven classical chemistry on the concentrate; per-stream configuration and field reference pending.
Six years of deficit met from a finite stock of already-mined metal, with industrial silver leaving circulation permanently as micron films. The recoverable increment inside existing water circuits is the cheapest incremental supply available — the metal is already mined, milled and dissolved.
Reference: one module, 200 m³/day, 73,000 m³/year, at $2,040/kg Ag.
Total: up to $16 M/year from one container on the richest stream described.
Wording rule for all external use: quote the total as "up to $16 M", never as a "$0.2–16 M" range. A two-order spread reads as not knowing your own economics.
Stream-tenor dependence (assay first); silver price volatility; finishing configuration per matrix; fixer volumes too small for a 200 m³/day module; needs a silver field reference.
