Passive biological treatments have been proposed as an efficient and cost effective treatment of metal bearing water discharged from mine sites after closure. However, concerns are typically expressed around biological treatments and their…

The objective of this study is therefore to evaluate the impact of freeze-thaw cycles on oxygen migration within saturated covers over tailings, by simulating a tailings cover system in the laboratory through column experiments. Covers for waste…

The goal of Yukon Passive Water Treatment Workshop was to foster discussions between mines environmental personnel, regulators, project managers, consultants, design engineers, and other affected stakeholders to identify the gaps that need to be…

The overall goal of this project was to assess, in three stages, the use of fish otolith microchemistry as a potentially new monitoring tool to be applied around Yukon mine sites. High quality environmental assessments are critical to sound land and…

Development of cost effective amendment technologies and restoration protocols for remediation and restoration of mine impacted sites is strongly needed in northern Canada. One of the first steps in developing successful restoration protocols is to…

Environmental and socio-economic effects assessment ensures that the effects of development activities are considered before they happen and that significant adverse effects will be mitigated. Dr. Amelie Janin, NSERC Industrial Research Chair in…

[T]his report explores a hybrid-applied solution: the use of saturated covers, which involve lifting an elevated water table into a tailing impoundment that maintains saturation within the tailing profile without allowing excess water directly along…

Conference presentation for the Science Community of Practice (SCOPe)

In this review, we evaluate the challenges encountered and the adaptations required for the successful treatment of mine-impacted waters in cold climates with Passive Treatment Systems (PTSs). Engineered PTSs are modeled on natural wetlands, which…

The purpose of this document is to report the results of the Bioremediation Project conducted by the Industrial Research Chair in Mine Life Cycle at Yukon College, between February 2013 to January 2014, to the industrial partners Alexco Resource…

Passive treatment systems offer a low cost and low maintenance means of remediating water contaminated by a variety of industrial and domestic factors. Natural wetlands demonstrate an innate ability to remove contaminants derived from mining/…

As passive water treatment technologies are increasingly being considered as a part of mine site closure in Yukon, it is important for industry to share with the government the questions they have, and vice versa. Efforts are currently underway by…

Passive treatment systems (PTS) present a potential low-cost solution to treating mine-impacted waters (MIW) and impeding release of contaminants, such as metals and sulphate, into receiving waters in remote mine sites in Yukon. Nevertheless, the…

The Northern Mine Remediation project began with the formation of the Yukon Mining Research Committee (YMRC) in 2012. As representatives of the mining industry they wanted to create a platform for industry, Yukon College, First Nations, and…

Constructed wetlands (CWs) have been employed as passive treatment systems for metal contaminated mine drainage in Canada. However, relatively few CWs have been documented in northern environments and further studies are needed to understand the…

In situ immobilization of metals using soil amendment processes is increasingly being considered as an effective and low cost remediation alternative (Mench et al. 2007, Kumpiene et al. 2008, Fellet et al. 2011). Leonardite is a carbon-rich material…

Four (4) pilot anaerobic bioreactors were commissioned at the Minto mine site in the summer of 2014 by Amelie Janin, NSERC Industrial Research Chair at Yukon College, and Capstone staff. Installation was completed on August 7th, 2014 and operation…

Passive water treatment technologies are increasingly being considered for mine site closure in the Yukon and efforts are currently underway to test, compare and contrast passive treatment technologies with conventional technologies. This study aims…

Northern Cross Yukon Ltd. is in the process of electing a treatment method for drinking water provision at their base camp situated in Eagle Plains, Yukon Territory (Canada). An experiment was conducted at the Yukon Research Centre for comparing…

A major environmental concern of the mining industry is the management of mine tailings. Mine tailings are the sulfide mineral by-products of ore beneficiation. Exposure of mine tailings to both water and oxygen cause acid-generating reactions to…

This document is meant as a report on, and a supplement to the Metals Uptake Database (www.yukoncollege.yk.ca/research), completed in the summer of 2017. It acts to summarize and report on certain aspects of the data contained within the database,…

The mine life cycle, from exploration to mine closure can be fast-paced and volatile, therefore careful consideration should be given to remediation planning of mine sites. Ensuring strategies are developed which are both cost effective, and…
