VANCOUVER — Lee Groat, a mineralogist and professor from the University of British Columbia, may have just cracked one of mining’s biggest environmental problems — acid rock drainage (ARD) — thanks to initial research funding from Yukon-explorer Strategic Metals (TSXV: SMD).
Groat and his students have found a way to combine acidic water generated from mine tailings with carbon-dioxide from gas emissions to make siderite, a stable iron carbonate mineral that won’t hurt the environment.
The ground-breaking research has landed Groat and Terra CO2 Technologies, a private research and development company spun-out of Strategic in October, in the semi-finals for the US$7.5-million NRG COSIA Carbon XPRIZE.
The competition encourages the development of technologies that convert carbon gas emissions from a potential liability to something less so.
