Crude Sn/Pb(Sb)-Sn alloy distilltation

Source of raw materials:

This process is applied for crude tin alloy with Cu, Fe, and Ni contents less than a certain proportion. The main sources for the raw aterials are:

  1. Crude soldering tin;
  2. Crude tin alloy of raw ore from traditional large-scale tin smelting plants;
  3. Tin and bismuth alloy;
  4. Tin base alloy with low impurities and low melting point;



Technological characteristics and finished product indexes:
