acid and metals into the environment. During the mining activity, ore is mined and processed to recover_x000D_
valuable metals. There are two main forms a waste materials including tailings and coarse waste rock. For the_x000D_
past 40 years mining operations have managed and remediated the waste dumps to prevent weather and metal_x000D_
leaching, referred to as acid rock drainage. However, historically, created waste dumps without remediation_x000D_
such that the abandoned legacy mine sites release acid waters and metals into the environment._x000D_
Sensor based sorting technologies have evolved in the past 15 years and are increasingly finding application in_x000D_
the mining industry. These technologies use sensors such as x-ray transmission and x-ray fluorescence to_x000D_
predict the sulphur or metal content of rocks. In the sorting machine, the rocks flow on a conveyor or across a_x000D_
chute sensing each rock and then triggering an actuator to deflect selected rocks. The research will test the_x000D_
technology on a selected waste rock dump in order to determine if sulphide mineral content of the waste_x000D_
material can be reduced sufficiently to reduce or eliminate the acid rock drainage., program purpose french : The objective of the research is to assess sensor based for the cleanup of legacy mining waste dumps that leach_x000D_
