Tailing Disposal an overview ScienceDirect Topics

For coal tailings, the dry density is about 1.8 t/m 3 due to their low G s, while for metalliferous tailings the dry density is up to 1.5 t/m 3 due to their higher G s. Figures 2.4a and b show typical wet and dry density and w profiles with depth for settled gold tailings from the Kalgoorlie Goldfields, Western Australia, obtained by testing borehole tube samples Golder, 1992 .

History of coal washing in India Kalyansen

2010128As some of the stone layers form partings of variable thickness in between coal seams, it is always possible to lose some coaly matters along with the wastes. The carbon content of these rejects can be as high as 10 to 15, which imparts them a blackish color not favorable as building materials.

Dry Stack Tailings Design Considerations

201759The shear strength of dry stack tailings will vary, depending on the moisture content and density of the tailings, and drainage conditions within the stack. From a design standpoint, it is important to recognize that the density, moisture content, and drainage conditions within the stack are changing as more tailings are placed in the dry stack.
