Pb/Cu Floating Slag Precious Metal Recycle Vacuum Distillation System

Pb/Cu Floating Slag Precious Metal  Recycle Vacuum Distillation System

Equipment Overview

• Decrease boiling point of metals in alloy under vacuum
• Distil & purify each low boiling point(≤2000°C) metal from alloy
• Leave & purify high boiling point metals
• Produce liquid metal or nanoscale powder by control of the condensation speed

Metals Pressure VS Boiling Temperature

Advantages

• Low energy consumption, 600~800kwh/MT raw materials
• High purity of metal product, ≥99.95%, Automatically operation
• Produce liquid metal and solid metal powder
• No off-gas, environmental friendly, hygiene working
• Low infrastructure cost, less construction area
• Large capacity, single furnace 10t/d, continuous or batch shift

Two Type of Vacuum Distillation Furnace System

Continuous Vacuum Distillation (CVD)

Batch Vacuum Distillation (BVD)

Three Main Aplication

• Cd: Cd low temperature molten salts (Cd or its oxides powder from Zn electro-winning), 

  Cd ingot (98%), Cd distillation slag, Cd-Ni batteries

• Zn: Zn ingot (98%), Zn (90~99%), hard Zinc (99.5%),  hot galvanizing Zn residue (Zn/Fe/Al alloy), Bi-Ag-Zn slag, Pb-Ag-Zn slag
• Pb: Pb/Cu floating slag from Cu removal process for Pb (95~98%) fire-refining, Cu or Pb anode slime with precious metal (Au/Ag), Pb secondary material
• Others: WEEE,Sulphuric acid sludge from acid generation plant of ZnS calcining, Crude Mg, etc.
