金属矿物公司利用新的生态友好型电子化学方法成功地从矿石中提取了99.9%的纯铜。 Metallic Minerals Corp. successfully extracted 99.9% pure copper from ore using a new eco-friendly electrochemical method.

在科罗拉多州La Plata项目中,金属矿物公司在利用新的电化学工艺从富含铬的矿石中提取99.9%的纯铜方面取得了实验室规模的成功。 Metallic Minerals Corp. has achieved lab-scale success in extracting 99.9% pure copper from chalcopyrite-rich ore at its La Plata project in Colorado using a new electrochemical process. 该方法与哥伦比亚大学共同开发,在四小时内在环境温度下溶解70%的铜,而不进行浮化或烧烤,同时利用现场产生的过氧化氢。 The method, developed with Columbia University, dissolves 70% of copper within four hours at ambient temperature without flotation or roasting, leveraging in-situ generated hydrogen peroxide. 铜通过高纯度电极回收,而银、稀土元素、白金组元素和黄金仍留在可回收的富含铁的残留物中。 Copper is recovered via high-purity electrodeposition, while silver, rare earth elements, platinum group elements, and gold remain in a recoverable iron-rich residue. 该系统再生试剂,使闭环低能操作成为可能。 The system regenerates reagents, enabling a closed-loop, low-energy operation. 这一突破可以提供一种熔炼的替代办法,支持国内加工和保留关键矿物的价值,并正在进行进一步研究,以回收残余物中的元素并评估知识产权保护情况。 The breakthrough could offer a smelting alternative, supporting domestic processing and value retention of critical minerals, with further research underway to recover elements in the residue and evaluate intellectual property protection.
