Abstract
A method of treating mineral tailings such as those derived from mining operations includes the steps of separating the slimes, forming alternate layers of slimes and a coarse material between peripheral berms and intermediate berms, the berms being of a coarse material, and allowing water to pass therethrough and away from the berms. The water moves through the berms by virtue of the pressure exerted on the lower layers by the mass of the layers above. The coarse material may be the coarse fraction of the mineral tailings.
