The What, Where, How and Why of Mine Tailings
Tailings are wastes comprising mixtures of crushed rock and processing fluids from mills, washeries, or concentrators that remain after the extraction of economic metals, minerals, mineral duels or coal from the mined resource. They contain potentially toxic metals and metalloids and can be very reactive, generating acidity or alkalinity and affecting ecosystem and human health. To understand their impacts we must ask the what, where, how and why questions.
