The CTRI collaborates with 6th Wave-AEM to validate the potential of green alternatives and innovative IXOS® moleculary imprinted technology to replace cyanide and activated carbon, respectively. The project is divided in two parts. Part 1 covers the trials for green alternatives for gold leaching. The tests and the validation of these alternatives will be a focus in this part. To attempt this goal, this phase will involve running tests in CTRI, collecting laboratory data for evaluating the performance of these products and their environmental risks. Thus, the study of the environmental toxicity of post-treatment waters and solids resulted as a second output of the whole process will be carried out. Further often, this phase will be used to analyse collected data and quantify key performance indicators (KPI) of these products compared to conventional process based on cyanidation (positive control). Part 2 of the project will be more focused on gold recovery with IXOS® technology at laboratory phase and pilot scale. The CTRI has seen the potential application of this technology for AEM. The economical study of IXOS® Molecularly imprinted polymer IXOS® resin for gold recovery will be carried out. This project builds for a long-term collaboration with 6th Wave Innovations Corp (6WIC) as they seek to establish highly effective technology into Abitibi marketplace.

CTRI 与 6th Wave-AEM 合作，验证绿色替代品和创新 IXOS® 分子印迹技术分别替代氰化物和活性炭的潜力。该项目分为两部分。第 1 部分介绍了金浸出的绿色替代方案的试验。这些替代方案的测试和验证将是本部分的重点。为了实现这一目标，这一阶段将涉及在 CTRI 中进行测试，收集实验室数据以评估这些产品的性能及其环境风险。因此，将对作为整个过程的第二输出的后处理水和固体的环境毒性进行研究。此外，与基于氰化（阳性对照）的传统工艺相比，此阶段通常用于分析收集的数据并量化这些产品的关键性能指标 (KPI)。该项目的第二部分将更加关注在实验室阶段和中试规模下利用 IXOS® 技术回收黄金。 CTRI 已经看到了该技术在 AEM 中的潜在应用。将开展 IXOS® 分子印迹聚合物 IXOS® 树脂用于金回收的经济性研究。该项目旨在与 6th Wave Innovations Corp (6WIC) 建立长期合作，因为他们寻求在 Abitibi 市场中建立高效的技术。
