NAIT and Umicore will work together to evaluate a technology for selective capture of cadmium from a cobalt feed which is part of a process used in Umicore's specialty materials production plant at Fort Saskatchewan. The cobalt powder is used in the production of cutting bits that are comprised of 10% cobalt and 90% tungsten carbide, vacuum sintered at high temperature. Cadmium, a highly toxic metal, is present in cobalt ore and is produced as furnace deposits in this process. The removal of cadmium before the furnace stage using Molecular Recognition Technology (MRT) will be an important improvement in this process. MRT is a highly selective separations technology that employs specially designed ligands that are chemically bonded to silica gel or polymeric solid supports to bind with a specific ion of interest in a solution. This technology will have a significant impact on the future of Alberta's chemical and materials manufacturing industries, improving

NAIT和优美科将共同评估一种从钴进料中选择性捕获镉的技术，该技术是优美科位于萨斯喀彻温堡的特种材料生产厂所用工艺的一部分。钴粉用于生产由10%的钴和90%的碳化钨组成的切割钻头，在高温下真空烧结。镉是一种剧毒金属，存在于钴矿中，并在此过程中作为熔炉沉积物产生。采用分子识别技术（MRT）在炉前阶段去除镉将是这一过程的重要改进。MRT是一种高度选择性的分离技术，其采用专门设计的配体，这些配体化学键合到硅胶或聚合物固体载体上，以与溶液中的特定感兴趣离子结合。该技术将对阿尔伯塔省化学和材料制造业的未来产生重大影响，改善
