Probing Study on Separating Pb, Zn, and Fe from Lead

Water-quenched lead slags are classified as hazardous materials because they contain a certain amount of heavy metals. In this study, coal-based direct reduction followed by magnetic separation was presented to separate Pb, Zn, and Fe from lead slag. Lead slag was mixed with coal and additive and treated in a laboratory tube furnace.

Probing Study on Separating Pb, Zn, and Fe from Lead

roasted slags by magnetic separation, and volatile metals vaporize into flue gas as dust. Therefore, coal-based direct reduction followed by magnetic separation process is suit-able for the disposal of lead slag and recovery of valuable metals. 2. Experimental 2.1. Materials Water-quenched lead slag was collected from Hechi in

Comprehensive recovery of lead, zinc, and iron from ...

Lead, zinc, and iron were recovered from jarosite residues using direct reduction followed by magnetic separation. The influence of the coal dosage, reduction temperature, and reduction time on the volatilization rates of lead and zinc and the metallization rate of iron were investigated. The results show that the volatilization rates of lead and zinc were 96.97% and 99.89%,

2021-12-10  In addition, the slag processed from the Waelz process, found in the dumps, has not been used as a secondary raw material to date. The elemental chemical composition of the slag has been determined, represented by compounds of calcium, silicon, iron, aluminum, carbon, and heavy non-ferrous metals, namely zinc and lead.

In the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 50-70%, and the sulfur content of sulfidic ores is in the range of 15-20%.

A novel process to upgrade the copper slag by direct ...

2019-4-1  An innovative technology for direct reduction-magnetic separation with the addition of Na 2 CO 3 and CaO was studied to upgrade copper slag assaying 40.33% Fe total and 0.65% Cu. It is difficult to recover iron and copper from the slag by direct reduction since the iron mainly occurs in fayalite and the copper exists in copper sulfide.
