With our unrivalled experience and expertise we can help the aluminium production industry to handle its waste streams in many ways.
Alumumium industry wastes including salt slags, spent pot liner and drosses are generally classed as hazardous because of their potential to react with water, even moisture in the air, to create toxic and explosive gases.
Moreover, they are highly variable from smelter to smelter and batch to batch.
In order to treat, or even safely store these wastes and where there is a potential for hydrolysis reactions to occur, it is essential to be able to charcterise them physically & chemically to understand the risks and hazards involved.
We can prepare all the required assessments for safe handling and storage and we can analyse all outputs from processing to assess their suitabilty, once treated, as secondary resources. If necessary, we can test and evaluate to confirm they meet WAC (waste acceptance criteria) for disposal as non hazardous, inert wastes.
We are well equipped with facilities, equipment and personnel to do this. We are able to prepare analyses using methods (amongst others) such as:-
ICP - Inductively Coupled Plasma Spectroscopy.
XRF - X-Ray Fluorescence.
XRD - X-Ray Diffraction.
Mobile XRF - Useful to assess the metallic & alloy composition of slags & drosses before treatment to maximise the economic benefit.
Gas evolution assessments - all done safely within our vented fume cupboards.
We have an in house team of highly qualified & experienced chemists plus, through our deep links with the Universities at Chester and Liverpool, we have access to highly specialised expertise & equipment if required.
This not only supports our acitivites assisting the industry but also our ongoing reseach & development programs for aluminium smelting wastes.
