Tailings - Resolution Copper

The mining process involves separating the copper ore from noneconomic rock. After removal of the copper, what remains is called 'tailings.' Tailings include particles of rock, water, and residual process chemicals. We will pump the slurry-like tailings via a pipeline to a designated facility for permanent storage.
