Over the last 25 years there have been reoccurring attempts to use spent aluminum potliner (SPL) in cement kilns. There are two major difficulties to overcome relative to the use of SPL, other than the off and on again approach to the issue that the aluminum industry has had on the issue.
Safe disposal of spent pot lining (SPL) of the cryolite bath is the greatest solid waste problem from aluminium smelting process. Pot lining is a layer of carbon situated between the molten metal and refractory material in side the steel shell of an aluminium reduction cell.
Potlining, that involves dismantling pot superstructures, digging spent potlinings and refractory, then rebuilding the potlining before rebuilding the superstructure.

UAE: Emirates Global Aluminium (EGA) has signed an agreement to supply 27,000t of spent pot lining (SPL) by 2020 to Gulf Cement. Although EGA has supplied SPL to the cement industry since 2010, the deal is the first directly between EGA and a cement company rather than via specialist third party preprocessors.
When an electrolytic pot reaches the end of its life, it is taken out of production and its contents are removed before it is rebuilt and put back into production. This process is called relining. The waste product of this process is called spent pot lining or SPL.
The pilot cells are equipped with improved steel shells and lining, modified busbar system and modern pot controller and pointfeeding system. To evaluate the most costeffective solution with best performance, four cells are provided with two point feeders and six cells with three point feeders.
Responsible aluminium: ASI's role; ... One of the main sources of waste production during the smelting process is 'spent pot lining' (SPL) from the relining of pots, which takes place every fivetoeight years. Leading companies minimise the generation of SPL by extending life times of the pots, and ensure proper handling of SPL waste ...
Spent pot lining (SPL) management represents a major concern for aluminum smelters. There are two key elements for spent pot lining management: recycling and safe storage. Spent pot lining waste can potentially have beneficial uses in cofiring in cement plants.
Site materials including concrete, metal and smelter wastes (such as separated spent pot lining) that can be recycled, will be, where it is a reasonable and feasible option. Stage 3 Remediation Some early remediation work has already been undertaken.
This paper continues of a review given in 1999 and resumes practices to treat the waste from used cathodes of the primary aluminium industry. The waste cathode lining consists of a carbon part and a refractory part. Spent potlining contains watersoluble fluorides and small amounts of leachable ...
1 Introduction Spent potlining (SPL) generation has been associated with primary aluminium production ever since the Hall–Héroult process became the technology of choice for the reduction of alumina to aluminium metal.
