Lead Tin Recovery Project

Lead-Tin Recovery Project

The Lead-Tin Recovery Project aims to extract tin metal from lead-tin alloys (Pb-Sn) and lead-tin-antimony alloys (Pb-Sn-Sb), which are byproducts of crude lead refining and lead-acid battery recovery. The lead-tin-antimony alloy serves as the core metallurgy component of this project.

FAQ

Q1: What payment terms do you accept?

A: We accept Letters of Credit (LC), Telegraphic Transfers (TT), and cash payments.

Q2: Do you provide installation services?

A: Yes, we offer installation services and can provide installation instructions online or through other methods to accommodate client needs.

Q3: Can you offer design services to clients?

A: Yes, we provide customized design services and products tailored to client specifications.

Q4: What are the raw materials and final products of the project?

A: The raw material is crude gold (gold-silver alloy) anode, and the final product is refined gold (Au ≥ 99.99%).

Q5: Can lead, zinc, and tin anode slimes be processed to produce precious metals like silver, gold, and selenium?

A: Yes, but an analysis report is required to design the appropriate processes and metallurgy equipment.

Q6: Can the gold electrolytic refining system operate fully automatically?

A: Yes, we can supply robots to automate certain processes, reducing labor intensity. However, these processes must be conducted under human supervision.
