The proponents of a Timmins-area nickel mine are promoting the open-pit project as one of the largest carbon capture storage facilities in Canada. ... Because Crawford is an ultramatic deposit, the tailings and other mine waste rock generated after milling naturally and spontaneously absorbs and sequesters CO2 (carbon dioxide) when …
One of the many benefits of this progress is the reduction of waste and dangerous chemicals. Nickel mining is still relatively young compared to other mined resources. Nickel was first discovered in a red-colored ore that German miners mistook for copper in the 17th century. They named the material "kupfernickel," which means "Old …
