项目摘要

The safe disposal of Spent Pot Linings (SPLs), the waste material generated in the de-lining of steel containers following the aluminium (AL) smelting electrolysis process, is a major environmental challenge as highly toxic & hazardous substances are absorbed into the cell lining (made up of carbon & refractory (ceramic) layers) in the process – making disposal extremely hazardous & expensive. Existing SPL disposal techs (e.g. Macro encapsulation, vitrification), do not look to recover metals or other valuable materials, but simply treat the material to reduce toxicity for landfill disposal. Ultromex have successfully completed PoC work around a novel treatment process which successfully makes the carbon layer from a SPL inert with the potential to re-use in other applications (e.g. new anodes). In order to develop a complete viable solution, Ultromex now seek to complete a 12 month Industrial Research project to investigate the feasibility of treating & de-contaminating the two refractory layers, through the use of novel proprietary mechanical & chemical treatment processes, at a single location & prove they are able to separate all streams – producing inert refractory material (that can be used to make new brick for the cathode cell or used in a wide range of brick products for the construction industry) & inert carbon material (used as an addition for either anode or cathode production or as a high quality fuel). If successful, Ultromex will revolutionise the AL smelting industry by providing a viable closed loop process to a major challenge.

安全的处理锅衬里（SPL）是铝（AL）冶炼电解过程中钢容器衬里产生的废料，这是一个重大的环境挑战，因为碳和危险物质具有高度有毒和有害物质被吸收到细胞衬里（由碳和倒流（陶瓷）层组成，使其在该过程中变得非常昂贵。现有的SPL处置技术（例如宏观封装，玻璃化），不希望收回金属或其他有价值的材料，而只是将材料处理以减少垃圾填埋场处置的毒性。 Ultromex已成功完成了新的治疗过程的POC工作，该过程成功地使SPL变化的碳层具有重新使用其他应用（例如新阳极）的潜力。为了开发一个完整的可行解决方案，Ultromex现在试图通过使用新型的机械和化学处理过程来调查一个为期12个月建筑行业）和惰性碳材料（用作阳极或阴极生产或高质量燃料的补充）。如果成功的话，Ultromex将通过为重大挑战提供可行的封闭循环流程来彻底改变Al冶炼行业。
