Recovery of Zinc and Lead From Brass Smelter Dust.

PB233422

Publication Date	1974
Personal Author	Fukubayashi, H. H.; Higley, L. W.
Page Count	15
Abstract	The work described herein, conducted by the Bureau of Mines, was done to develop data necessary for a pyrometallurgical process for the recovery of the zinc and lead contained in brass smelter flue dusts. Tests on brass flue dust from several sources were made in a quartz tube, heated by an electric furnace to temperatures as high as 1,050 C. The dusts were mixed with carbon and heated in an oxygen-free atmosphere. It was demonstrated that 98% of the zinc and 12 to 25% of the lead, both in the metallic state, could readily be removed from the dusts. It was also found that 75% of the zinc could be recovered, with less than 0.1% of the lead, in the absence of chlorides. Pelletization techniques were investigated and pellet size was found to be important. Pelletizing results in a 10-fold reduction in volume. (Modified author abstract)
