How to prevent flow failures in tailings dams | springerlink

Feb 17, 2021 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

dec 01, 2014 1. introduction. an estimated 1150 million tons of heavy metals (copper, lead, cobalt, zinc, cadmium and chromium) have been mined since the stone age with estimates of contemporary mine tailings production ranging between 5 and 7 billion tonnes per year worldwide (lu and wang, 2012, mudd and boger, 2013).mine tailings consist of the remaining fine grained (1–600 μm) ground-up

industrial solid waste can be divided into general industrial waste (such as blast furnace slag, steel slag, red mud, non-ferrous metal slag, fly ash, cinder, sulfuric acid slag, waste gypsum, desulphurization ash, calcium carbide slag, salt mud, etc.) and industrial hazardous solid waste. among them, the most common is the former, such as
