项目摘要

Refining gold is an essential business in many countries, including Canada. Gold is a precious metal playing important societal roles. It is a form of currency, an investment, a component of jewelry and decoration, and increasingly, an essential component of electronics. In each of these applications, the most important factor governing its performance is purity. In partnership with the Royal Canadian Mint, the McGill Laboratories of Profs Friscic, Lumb and Mauzeroll are combining their expertise to improve the gold purity during electrolysis and reduce the environmental footprint of their gold production process. The proposed research will develop an environmentally sensitive technology that could displace current gold refining practices. In particular, RCM seeks to capitalize on recent advances in mechano- and electro-chemistry to produce high purity gold with higher efficiency and throughput than existing methods. The new process will also minimize the negative impacts of gold refining to worker health and safety, and the environment. If successful, this collaboration will provide a disruptive technology that will dramatically change the environmental footprint of gold refining worldwide. It would also create an important blueprint for additional innovation in the refining sector, which is a major contributor to environmental degradation.

提炼黄金是许多国家的基本业务，包括加拿大。黄金是一种贵金属，发挥着重要的社会作用。它是一种货币形式，一种投资，一种珠宝和装饰的组成部分，越来越多地成为电子产品的重要组成部分。在这些应用中，控制其性能的最重要因素是纯度。麦吉尔实验室的Friscic、Lumb和Mauzeroll教授与加拿大皇家造币厂合作，结合他们的专业知识，提高电解过程中的黄金纯度，减少黄金生产过程中的环境足迹。拟议的研究将开发一种环境敏感的技术，可以取代目前的黄金精炼实践。特别是，RCM寻求利用机械化学和电化学的最新进展，以比现有方法更高的效率和产量生产高纯度黄金。新工艺还将最大限度地减少黄金精炼对工人健康和安全以及环境的负面影响。如果成功，这项合作将提供一种颠覆性的技术，将极大地改变全球黄金精炼的环境足迹。它还将为炼油部门的进一步创新创造一个重要的蓝图，炼油部门是环境退化的主要原因。
