Tailing Disposal Methods and Tailings Dam Construction Design

Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.

an overview - sciencedirect.com

The tailings are often treated with lime to neutralize acids and precipitate heavy metals as insoluble hydroxides before pumping to the dam. Such treated tailings may be thickened, and the overflow, free of heavy metals, returned to the mill (Figure 16.9), thus reducing the water and pollutant input to the tailings dam.
