SBIR Phase II: Copper Selective Silica-Polyamine Extraction Materials for Processing Copper Ore Leach Liquors

这个小型企业创新研究（SBIR）第二阶段项目将研究一种令人兴奋的新材料CuWRAM（从水介质中回收铜废料）的生产。 这些中试程序的评价将支持全规模生产设施的设计。 将生产一个处理系统，该系统利用从Calgon Carbon Corp.和CuWRAM获得的专利ISEP分离硬件作为铜提取和铁（III）分离的提取剂材料。广泛的测试将提供信息：（1）确定CuWRAM-ISEP系统在真实的样品上的有效性;（2）确定该系统在各种条件下的经济可行性;（3）根据前两项制定有针对性的营销策略。第一阶段项目的结果在整个采矿界引起了兴奋。实际采矿解决方案的初步测试将与美国最大的铜生产商之一进行。CuWRAM铜提取的商业应用包括用于铜矿开采作业的主要提取回路、回收铜用于镀铜工艺以及从修复项目中回收铜。

This Small Business Innovation Research (SBIR) Phase II project will investigate production of an exciting new material CuWRAM (Copper Waste Recovery from Aqueous Media). Evaluation of these pilot procedures will support the design of full scale manufacturing facilities. A processing system utilizing the patented ISEP separations hardware obtained from Calgon Carbon Corp. and CuWRAM as the extractant material for copper extraction and separation from iron (III) will be produced. Extensive testing will provide information to: (1) establish the effectiveness of the CuWRAM - ISEP system on real samples; (2) establish the economic feasibility of this system under various conditions; and (3) develop a targeted marketing strategy based on the first two items. Results from the Phase I project have generated excitement throughout the mining community. Initial testing on actual mining solutions will be conducted with one of the largest copper producers in the U.S. Commercial applications for a CuWRAM copper extraction include use in the primary extraction circuit of copper mining operations, recovery of copper for reuse in copper plating processes and recovery of copper from remediation projects.
