RECYCLING SPL REFRACTORY FOR COMMERCIAL USE.

废旧罐衬(SPLs)是铝(Al)冶炼电解过程中在钢容器脱衬过程中产生的废物，它的安全处置是一项重大的环境挑战，因为在该过程中，剧毒和危险物质被吸收到电解槽衬里(由碳和耐火(陶瓷)层组成)中，这使得处置极其危险和昂贵。现有的固体废物处理技术(例如宏观包埋、玻璃化)并不是为了回收金属或其他有价值的材料，而是简单地处理这些材料以降低垃圾处理的毒性。Ultromex已经成功地完成了围绕一种新的处理工艺的PoC工作，该工艺成功地使SPL中的碳层具有惰性，并有可能在其他应用中重复使用(例如，新的阳极)。为了开发完整可行的解决方案，Ultromex现在寻求完成一个为期12个月的工业研究项目，通过在一个地点使用新型专有机械和化学处理工艺来研究处理和去除两层耐火材料污染的可行性，并证明它们能够分离产生所有蒸气的惰性耐火材料(可用于制造阴极电池的新砖或用于建筑业的各种砖产品)和惰性碳材料(可用作阳极或阴极生产的添加剂或用作高质量燃料)。如果成功，Ultromex将通过提供可行的闭环流程来应对重大挑战，从而彻底改变铝冶炼行业。

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.
