A compact, high-efficiency greenfield plant: acid digestion, atmospheric oxidation, alkaline precipitation and calcination in a closed-loop configuration.
Process 01 · Cu₂(OH)₃Cl
Secondary copper wire is loaded into 300 L glass-lined assemblies and charged with hydrochloric acid plus recycled mother liquor. Continuous compressed-air sparging maintains 65–75 °C oxidation; saturated liquor precipitates fine green oxychloride crystals, which are centrifuged, fluid-bed dried, pulverized and packed. Mother liquor returns to the reactor for the next batch.
4Cu + 2HCl + 3O₂ + 2H₂O → 2Cu₂(OH)₃Cl ↓
Process 02 · CuO
Copper is digested in an acid intermediate bath; metered caustic dosing precipitates copper hydroxide, which is centrifugally isolated. The cake is calcined in an indirectly heated rotary kiln, dissociating to dense cupric oxide — then milled to target particle-size profiles and packed.
Cu²⁺ + 2NaOH → Cu(OH)₂ ↓ →(Δ) CuO + H₂O ↑
Plant infrastructure
Glass-lined batch digestion vessels with stirrers and cooling jackets; AOD pumps; SS-316L bottom-discharge basket centrifuges; nutsche filtration.
Drying and calcination run on electrical resistance and indirect induction heating — no fuel-oil boilers, dramatically lowering stack emissions.
Dual-stage alkaline scrubbing tower with internal negative-draft ducting and GPCB-compliant exhaust stack.
PP/PVDF process piping, acid-resistant epoxy flooring, anti-corrosive lined storage tanks and 110% bunded acid containment.
60 KVA grid connection (DGVCL) with a 45 KVA silent DG set on automatic transfer — keeping cooling pumps and scrubbers live through outages.
Fire extinguisher network, hose reels and hydrant points, 5 KL firewater tank with pressure pump loop, eye-wash stations, drench showers and lime neutralization depots.
