Lead Battery Slag which is from recycling lead acid line, is the lead-tin alloy(Sn5~35%, Pb 50~93%, remainders are impurities ).
The Lead-Tin vacuum distillation unit, also known as the Lead-Tin-Antimony metal vacuum distiller unit and lead-tin alloy separating vacuum distillation furnace, is utilized for the separation of Tin from lead alloy, which is a byproduct of lead smelting. This process exploits the varying boiling points of Tin, Antimony, and Lead under different vacuum conditions to eliminate impurities.
Operating under vacuum, the Pb-Sn-Sb VDF induces distinct boiling points for various metals. Within the VDF's graphite tray, the vapors of lead and tin condense at different locations, resulting in the formation of liquid lead and tin.
The Pb-Sn-Sb VDF relies on electricity for heat generation and operates without emitting any gases, rendering it environmentally preferable. It also incorporates a method for arsenic collection when present in low concentrations (As≤1%). However, if the arsenic content exceeds a certain threshold (As≥2%), it must be removed before furnace utilization.
