A Guide to the Management of Tailings Facilities - Mining

A Guide to the Management of Tailings Facilities provides a basis for the development of customized tailings management systems that address the specific needs of indi- vidual mining companies and local regulatory and community requirementsTailings - Wikipedia,Tailings ponds can also be a source of acid drainage, leading to the need for permanent monitoring and treatment of water passing through the tailings dam; the cost of mine cleanup has typically been 10 times that of mining industry estimates when acid drainage was involvedICMM & Tailings management,From the mill, the tailings is often pumped to surface storage facilities which are commonly constructed using earth dams These range in size from a swimming-pool to areas over 1,000 hectares

ICMM & Tailings management

From the mill, the tailings is often pumped to surface storage facilities which are commonly constructed using earth dams These range in size from a swimming-pool to areas over 1,000 hectares As the sandy residue of tailings gradually drains and becomes compact and dry, grass and other vegetation is planted to stabilise the environment This is called the reclamation processSRK Paper: Management of uranium tailings,Uranium tailings are differentiated from other types of tailings due to the radioactive nature of the material Radioactive tailings facilities pose long term hazards relating to both exposure and dam failure, with the principal concern being the potential harm to both operator and public healthManagement of risks associated to mining wastes (tailings ,The paper presents significant aspects regarding risk management related to wastes in the Romanian mining industry There are studied two subjects of interest: the waste heaps and tailing dams

“tailings dam” encompasses embankments, dam walls or other impounding structures, designed to enable the tailings to settle and to retain tailings and process water, which are constructed inBHP | Dams and tailings management,A risk review was conducted of all significant dams across our operated assets and the assets of our NOJVs in FY2016, which confirmed the dams to be stableConference Program – Tailings & Mine Waste 2018,Keynote Presentation 1 - Recent advances in tailings testing methods Prof David Williams MAusIMM, Director, Geotechnical Engineering Centre, Manager, Large Open Pit Project, School of Civil Engineering, The University of Queensland

Tailing Disposal Methods and Tailings Dam Construction Design

Tailing Dams The tailing dam should be situated where the slope of the ground enables the pulp to be retained with the minimum length of artificial embankment, since its height has to be raised at frequent intervals as the basin becomes full The area enclosed must be large enough to allow of the settlement of the solid material, including the finest slime, at the maximum rate of inflow, so that clear water can beManagement of Uranium Tailings - srkcoza,Generally, the causes of dam failure at uranium facilities are no different from those at other mill tailings dams However, the consequences of failure may be more significant than non-hazardous facilities, depending on the radioactivity of the material and the sensitivity of the receiving environmentBHP | Dams and tailings management,Dams and tailings management A risk review was conducted of all significant dams across our operated assets and the assets of our NOJVs in FY2016, which confirmed the dams to be stable Tailings dams require continuous monitoring and maintenance, so our focus has shifted to risk identification, governance and monitoring programs

Seepage Control for Tailings Dams

SEEPAGE CONTROL FOR TAILINGS DAMS 671 The tailings were discharged by spigotting off the top of the starter dyke When the initial pond was nearly filled, the dyke was raised by borrowing material from the dried surface of the previously deposited tailings, and the cycle was repeated As the height of such a dam increases, each successive dyke moves further upstream, and is underlain by the Mine tailings dams: Characteristics, failure ,Tailings dam spills can contaminate natural waters in the short-term, but in the medium- to longer-term (years to centuries) contaminant concentrations are likely to fall because of the effects of sediment and aqueous dilution and uptake by solid phases in the river bed and floodplain,
