Cyclone Electrorefining System

Product Family: AVER Cells + AVCC Anode-Casting Furnaces   |   Complete anode-to-cathode flow for copper, PGM & precious-metal refining · Titanium cyclone cathode · LME Grade A output

Cell Cathode	DC Current Per Cell	Anode Casting	Cathode Purity	Lead Time
Ø250 × 500–2,000 mm	300–800 A	100–300 kg / batch	99.99% Cu (LME)	30–60 days

How the System Works

1. Smelter feed or concentrate plus collector metal Cu / Ni / Fe is melted in the AVCC continuous casting furnace.
2. The melt is drawn through the Intelligent Traction Machine to form a tubular copper anode Ø140 mm × 1,200 mm with 10–15 mm wall thickness.
3. The anode is loaded into an AVER cyclone electrorefining cell with a titanium starter-sheet cathode.
4. DC current dissolves copper from the anode and deposits pure copper on the cathode as 99.99% LME Grade A copper.
5. Noble metals such as Au, Ag, Pt, and Pd do not dissolve and settle at the bottom as anode slimes.
6. Slimes are processed in the Cyclone Electrowinning System AVEW to selectively recover individual precious metals.

AVER Cyclone Electrorefining Cells

Three vertical-cyclone cell sizes are available, all with 250 mm cathode diameter and different heights and current ratings. Cells stack in modular arrays for higher production.

SKU	Cathode	Anode Holder	DC Power	Cu Deposition	Standard Features
AVER-250-500	Ti, Ø250 × 500 mm + starter sheet	Ø140 mm	0–6 V / 300 A	~0.34 kg Cu/h · ~8 kg/day	Anode filter, Ti starter sheet
AVER-250-1000	Ti, Ø250 × 1,000 mm + starter sheet	Ø140 mm	0–6 V / 500 A	~0.57 kg Cu/h · ~14 kg/day	Anode filter, Ti starter sheet
AVER-250-2000	Ti, Ø250 × 2,000 mm + starter sheet	Ø140 mm	0–6 V / 800 A	~0.91 kg Cu/h · ~22 kg/day	Anode filter, Ti starter sheet

Copper deposition is calculated from Faraday's law at typical 95% current efficiency for electrorefining duty. Actual production depends on solution chemistry, anode purity, and operating temperature. Cells deploy in modular arrays of 10–40 cells per industrial bank.

AVCC Continuous Anode Casting Furnace

The AVCC furnace melts concentrate plus collector metal Cu / Ni / Fe and continuously casts tubular copper anodes for the AVER cells.

Key Features

• Cyclone-flow refining: Vertical vortex circulation accelerates ion migration and improves efficiency compared with traditional flat tank houses.
• Titanium cathode: Long-life starter sheet with easy cathode peel-off for high-purity copper harvest.
• Tubular anode design: Continuous-cast tubular copper anodes Ø140 mm deliver uniform dissolution and stable current distribution.
• Anode filter cartridge: Captures anode slimes for separate precious-metal recovery with no manual cell cleaning between batches.
• Integrated upstream casting: AVCC furnace pre-casts anodes in-line with refining demand, eliminating the need to source anodes externally.
• Continuous slime to AVEW recovery: Anode slimes feed directly into Avimetal's Cyclone EW system for Au / Ag / Pt / Pd selective recovery.
• Modular & scalable: Stack cells into 10-, 20-, or 40-cell industrial banks and pair with one or multiple AVCC furnaces to match throughput.
• Closed-loop operation: Electrolyte and cooling water both recirculate, reducing effluent for ESG-compliant operations.
