Under these experimental conditions, the percentages of metal recovery were 94.7% for Pb, 99.5% for Sn, and 99.7% for In. Barakat (1998) investigated metal recovery from zinc solder dross used in PCBs by means of leaching using a 3.0% H 2 SO 4 solution at 45ºC for 1 hour. Zinc and aluminum entered the solution, whereas lead and tin remained

Recovery of Tin from Tinhouse Scruff Metal AusIMM

A modified liquation technique was developed for recovering tin from tinhouse scruff metal or hardhead containing about 10 per cent iron and 15 per cent occluded flux, palm oil, and moisture. This was effected by heating the scruff metal to 950°C followed by rapid cooling to suppress the formation of FeSn2 and FeSn, and then
