Lead slag is produced by the primary and secondary lead industry. The large amount of lead
slag discharge causes environmental problems. Reducing the toxicity and increasing …

China is the largest lead-acid battery (LAB) consumer and recycler, but suffering from lead
contamination due to the spent-lead recycling problems. This paper describes a …

Lead recycling is very important for reducing environmental pollution risks and damages.
Liquid lead is recovered from exhaust batteries inside stirred batch reactors; the process …

This study presents the solidification/stabilisation and immobilisation of lead smelting slag
(LSS) by its incorporation in coal fly ash–blast furnace slag based geopolymers. It also …

Several HNO 3-based leaching approaches were tested and optimized to selectively
recover Pb and other minor metals (Cu, Ni, Zn) from secondary lead smelter residues (ie …

Lead slags from two different metallurgical technologies (primary slag from Pb-ore
processing and secondary slag from car battery recycling) were submitted to 12-year batch …

Slags are by-products generated by the pyrometallurgical processing of both ferrous and
non-ferrous metal ores and secondary resources (recycling). They are formed during …

The traditional sodium desulfurization process for waste lead-acid batteries is beneficial to
the environment; however, it is limited by poor economic viability as the cost of desulfurizer …

Abstract Lead (Pb) and zinc (Zn) smelters produce high amount of granulated slags which
are currently stored on unconfined slag heaps and exposed to weathering. The …

The pyrometallurgic process that the exhausted batteries are submitted for the recovery of
metallic lead generates great amount of a by-product called slag. The slag is composed …
