Reuse of secondary lead smelter slag in the manufacture
2000-1-1 The influence of the lead slag on the hydration chemistry has been studied by means of cementitious mixtures containing up to 65% powdered slag. The results have shown that the hydration chemistry is not negatively influenced from both the qualitative and quantitative points of view, provided that the lead slag content is within 30% Concrete ...

Utilization of secondary lead slag as construction material
2005-6-1 Secondary lead slag is a waste product of the transformation of lead sulfate (PbSO 4) and lead oxides (PbO and PbO 2) from expired batteries into metallic lead (Pb) using a rotary furnace. In this process, calcium carbonate (CaCO 3) is used as flux, while coal char and iron scraps are added as reducing agents.

Leaching of toxic elements from secondary alkaline lead
2019-7-12 Secondary alkaline lead slag (SALS), generated during lead–acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under atmospheric condition for 30 days, the SALS was sieved and coarse fraction (+ 1 mm) was returned to the recycling process.

Reduction in toxicity and generation of slag in secondary
2011-6-1 In Brazil, lead is produced entirely from secondary processes, mainly from the recycling of lead-acid battery scrap. The slag generated in the rotary furnaces is classified as hazardous waste in accordance with Brazilian norm ABNT NBR 10004 ( Associação Brasileira de Normas Técnicas (ABNT), 2004) and is disposed of in landfills.
