what is tailings treatment

Lecture 4 Mining waste

Water treatment can be categorized in active or passive treatment Active water treatment means that the water is treated within a water treatment facility The methods for active treatment are several but often include raising the pH of the water with the addition of for example limestone or caustic soda which in turn cause metals to...

Tailing Disposal

After settling and self-weight consolidation the dry density of the undesiccated tailings is a function of the G s of the tailings solids For coal tailings the dry density is about 18 t/m 3 due to their low G s while for metalliferous tailings the dry density is up to 15 t/m 3 due to their higher G s Figures 24 a and b show typical wet and dry density and w profiles with depth for...
