About this scholarship
Potential aquifer vulnerabilities to mining activities especially in emerging in-situ recovery (ISR) operations are a constant concern for government regulatory bodies, environmental activists, the public, mining operators, and research communities. It has a direct impact on social acceptance and long-term positive collaboration of the abovementioned stakeholders. A considerable number of studies and fascinating technologies have been developed in the past few decades to address this issue, but the majority were focused on the time that mines are operational rather than considering the closure and behind. Considering the later stages of a mine afterlife during the feasibility stage is of vital importance as some of the activities will impact the environment and especially the aquifer irreversibly. In the first stage of this project, we are trying to identify the gaps in data and techniques for mitigating these vulnerabilities. This literature review will also include investigating the type and properties of barrier agents that are compatible with aquifer and mining activity.
The mining industry currently faces challenges including ore grade declination, incremental operating depth, backfilling, cost, and finally environmental problems like tailings. In-situ recovery (ISR) offers an alternative way to extract target minerals from the deposits without costly processing. However, when the orebody is non-permeable, applying a stimulation technique, e.g. hydraulic fracturing, is necessary to artificially create a conductive flow channel for the leaching agent, i.e. lixiviant, to reach the targeted mineral. In the second stage of this project, we will investigate a similar but hybrid blasting-hydraulic fracturing technique to engineer a barrier around the ore body. The ore body will be isolated from the over-, side-, lower-, and/or in-formation hosting the aquifer by injection of a reversible barrier blocking agent. The project is mainly experimental.
An Internship opportunity may also be available with this project.
