Tailings Pumping Design

 · Tailings Pumping Design. May 08, 2019. Current trends with tailings pumping often require transportation along relatively long distance pipelines. Combined with the presence of a high solids concentration, the slurry will have a high viscosity and will have a significant effect on the discharge head required for pumping.

How to Prevent Flow Failures in Tailings Dams | SpringerLink

 · Based on research carried out at 67 tailings dams in Spain: (1) tailings dams contain alternating sedimentary layers with contractive and dilative geomechanical behaviours; (2) tailings saturate quickly but drain more than 10 times slower due to the high-suction capacity of the porous sediments (2–300 MPa); and (3) over the long-term, a stationary flow regime is attained within a tailings ...

(PDF) STATIC LIQUEFACTION IN TAILINGS DAM AND …

Conclusion and discussion The tailings (sand, silt) liquefaction occurs if there are three conditions: 1) tailings are contractive, 2) saturated and 3) effective stress is zero. But for the flow failure to occur, it is necessary that the shear stress exceeds the undrained residual resistance (Su, Figs. 3, 4).

Use of iron ore tailing from tailing dam as catalyst in a …

The global demand for iron ore with high iron contents to supply the steel industry is associated, in most countries, with the generation of tailings from mineral processing. The chemical compositions of iron ore tailings (basically Fe 2 O 3 and SiO 2) make them an excellent candidate as a catalyst for advanced oxidation processes (AOPs), especially the Fenton process and its derivatives.
