This Engage application aims at establishing a research partnership between Goldcorp Inc. and Dr. Ye at Laurentian University to develop iron oxide/carbon nanocomposite adsorbents for arsenic removal from gold mine effluents. Arsenic is often associated with gold-containing ores and is thus often present in industrial gold mine effluents. Due to its high toxicity and strict environment regulations, the capture and safe removal of arsenic present in mine effluents before their release to the environment is critical to reduce the environmental impacts of the mining activities for sustainable development. We herein aim to develop a class of low-cost iron oxide/carbon nanocomposite adsorbents of high capacity for the adsorption of arsenic from gold mine effluents. A systematic study on the nanoscale structure of the nanocomposite adsorbents and their performance in arsenic adsorption will be undertaken. The success of this research may lead to an arsenic adsorbent technology, which may find applications in the industry for gold mine wastewater treatment.

此Engage应用程序旨在与Goldcorp Inc.与Laurentian大学的Ye博士合作开发氧化铁/碳纳米复合吸附剂，用于从金矿废水中去除砷。砷通常与含金矿石有关，因此通常存在于工业金矿废水中。由于其高毒性和严格的环境法规，在释放到环境中之前捕获和安全去除矿山废水中的砷对于减少采矿活动对环境的影响以实现可持续发展至关重要。本文旨在开发一类低成本的高容量氧化铁/碳纳米复合吸附剂，用于吸附金矿废水中的砷。本文将对纳米复合吸附剂的纳米结构及其对砷的吸附性能进行系统的研究。这项研究的成功可能会导致一种砷吸附剂 该技术可能在金矿废水处理行业中得到应用。
