In an ongoing research, the Harrison Environmental Services Inc. company is pursuing an efficient and cost effective methodology for the extraction of precious metals and base metals from their respective ores using hydrometallurgical-based methods that are friendly to the environment. In its effort to have mining and processing protocols that diminish any negative impact to the environment, the company is striving to have methodologies in place that minimizes wastes of the used leach-solutions by seeking to recycle them. Also, the stabilization of any residues before their disposal comprises a major emphasis of the ongoing research. Such practices would go a long way protecting the environment and in particular surface waters. The NSERC Engage Plus grant will equip me, as the principal investigator, with the material and personnel needed for the ongoing project. The funding obtained from the Engage Grant for this project has gone a long way in meeting the company's goals. To completely realize the company's goals, I am proposing a 6-month plan of research. Temperature, pressure, and pH are part of the parameters that will require optimizing for leaching of the metals being sort. As well, in order to minimize wastes, optimal ratios of lixiviates that include suitable oxidizing agents will be sort. Further investigation will look at stabilizing residues from the reactions before disposal. The results obtained up to this point through NSERC Engage grant appear very promising. The technology sort by the company will improve the latter's operations in a manner that will be commercially profitable. Once in place, it is anticipated that the technology will cut production costs significantly enough for the company to run at a profit. This will allow the company to grow and enlarge its work force. The minimization of wastes for mining processes may significantly reduce health concerns for the local communities.

在一项正在进行的研究中，哈里森环境服务公司正在寻求一种高效且成本低廉的方法。 使用以下方法从各自的矿石中提取贵金属和贱金属的有效方法 基于湿法冶金的方法对环境友好。在努力拥有采矿和 该公司正在努力减少对环境的任何负面影响的处理协议 通过寻求回收利用过的浸出溶液来最大限度地减少浪费的方法。另外， 任何残留物在处置前的稳定化是正在进行的研究的重点。这样的 这些做法将大大有助于保护环境，特别是地表水。 NSERC Engage Plus 赠款将为我（作为首席研究员）提供材料和人员 正在进行的项目所需的。该项目从 Engage Grant 获得的资金已经持续了很长时间 实现公司目标的方式。为了彻底实现公司的目标，我建议为期6个月 研究计划。温度、压力和 pH 值是需要优化的参数的一部分 正在分类的金属的浸出。此外，为了最大限度地减少浪费，浸出液的最佳比例包括 将筛选出合适的氧化剂。进一步的研究将关注反应中的稳定残留物 处置前。到目前为止，通过 NSERC Engage 拨款获得的结果似乎非常有希望。 该公司的技术分类将以商业化的方式改善后者的运营 有利可图。一旦到位，预计该技术将显着降低生产成本 公司以盈利为目的运行。这将使公司能够发展并扩大其员工队伍。这 最大限度地减少采矿过程中的废物可能会显着减少当地居民的健康问题 社区。
