Hard Zinc Hot Galvanizing Zn Residue (Zn/Fe/Al Alloy) Recovery Vacuum Distillation System
Hard Zinc Hot Galvanizing Zn Residue (Zn/Fe/Al alloy) Recovery 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.
