Lead scrap processing in rotary furnaces: A review

Jan 01, 1987 Pergamon Journals Ltd. LEAD SCRAP PROCESSING IN ROTARY FURNACES: A REVIEW MICHEL ROUSSEAU 1. Introduction High efficiency in lead scrap recycling has been well known for a long time [1]. Lead recycling ranged in relation of the 1984 consumption at 46 $ in the F.R.G., 53 $ in the U.S.A. and 49 8 in the Western World.

12.11 Secondary Lead Processing

Rotary furnaces are usually used to process low-lead-content scrap and residue, while reverberatory furnaces are used to process high-lead-content scrap. The partially purified lead is periodically tapped from these furnaces for further processing in smelting furnaces or pot furnaces. 12.11.2.2 Smelting -

residues are usually put through jaw crushers. This separated lead scrap is then sweated in a gas-or oil-fired reverberatory (SCC# 3-04-004-05) or rotary furnace (SCC# 3-04-004-04). The sweating process separates lead from metals with higher melting points. Rotary furnaces are usually used to process low lead

leach residues, drosses, ashes, residues from lead chemicals production, lead glass residues, roofing lead, and lead scrap are also of interest. Battery scrap is mechanically processed before smelting the lead containing fractions. Some plants work with a feed of drained whole batteries for shaft furnaces or even rotary furnaces.

Lead processing Lead processing Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc-desilvering process is the most widely used

Lead Processing

The lead containing components are processed in blast furnaces for hard lead or rotary reverberatory furnaces for fine particles. The blast furnace is similar in structure to a cupola furnace used in iron foundries. The furnace is charged with slag, scrap iron, limestone, coke, oxides, dross, and reverberatory slag.

is then used to reduce the lead fractions and pro-duce lead bullion. Most domestic battery scrap is processed in blast furnaces, rotary furnaces, or reverberatory furnaces. A reverberatory furnace is more suit-able for processing fine particles and may be op-erated in conjunction with a blast furnace. Blast furnaces produce hard lead from charges
