破局资源循环难题!科海思创新技术助力有色金属与稀贵金属高效回收
Sou Hu Cai Jing· 2025-08-20 07:19
在全球资源日益紧张、"双碳"目标加速落地的大背景下,有色金属与稀贵金属的高效循环利用,已然成为守护产业链安全、推动绿色转型的关键命题。然 而,传统回收工艺长期受困于处理阈值限制、二次污染风险及贵金属损耗等问题,严重制约着行业的高质量发展。在此形势下,科海思凭借自主研发的分 离与回收技术体系,聚焦镍钴分离、稀贵金属提纯等核心场景,为资源高效循环开辟了一条新路径。 行业痛点:传统工艺遭遇三大瓶颈 科海思摒弃了传统的路径依赖,采用"膜精密过滤+稀贵金属吸附系统"协同作用的方式,实现了镍钴离子的高选择性分离。其中,所选用的二甲基吡啶胺 官能基螯合树脂表现尤为突出,在100g/L的高浓度钴液中,可将镍离子脱除至0.1mg/L以下,大幅提升了镍钴分离效率。在此基础上,通过氨水解析与蒸 发浓缩系统的耦合,再生液中的镍钴浓度可提升至15-30g/L,为后续资源提取提供了高浓度原料保障。经此工艺处理后,镍钴萃余液的残留量稳定控制在 ≤0.01mg/L。 稀贵金属回收:从"微量残留"实现"深度净化" 针对汞、铂、金、铼等稀贵金属,科海思创新性地提出了"五级净化"工艺,即污酸→板框压滤→膜精密过滤→稀贵金属吸附系统→氨水解析系统→ ...
