·Ecological engineering of tailings has been advocated to change tailings mineralogy improve physicochemical properties and accelerate soil formation pedogenic processes allowing the re colonisation of microbial communities and pioneer plant species Huang et al 2012 These early settlers in turn act as powerful biological drivers to advance
The gold mine tailings of this study were shipped to Western s soil mechanics laboratory from the Goldex mining site located in the Abitibi region of Qubec Canada as shown in Fig 1 a These tailings are a silty sand with a non plastic fines content particles finer than mm with a plasticity index of zero of about 18%
·tailings sand which allows for use of medium sized mining equipment for reclamation Sand capped tailings can be reclaimed to a mix of upland forests and wetlands Regional Guidelines
·conventional tailings storage facilities in the database are presented in this paper Tests on paste tailings filtered tailings and oil sands tailings are not included Laboratory and field characterisation of tailings properties and behaviour has been reported in the literature by several others Qiu and Sego 2001
Tailings are found during the exploration and processing of mineral ores They contain a mixture of grounded rocks processed effluent and some trace elements that have the potential to damage the environment Recent urbanisation has led to a large stockpile of tailings in many mining environment constituting health hazard It becomes very important to develop disposal
·In order to fully utilize tailings Wang et al [35] used gold tailings powder and sand to replace cement and river sand respectively in UHPC mixtures and obtained a low carbon footprint UHPC design which showed nearly 25% reduction in the global warming potential Therefore it is necessary to investigate the feasibility of utilizing ITP
·corresponds to upstream sand tailings dams that failed as a consequence of a major earthquake Among those failures the most important ones are the failures of Barahona dam and El Cobre dam The Barahona N° 1 tailings dam that failed during December 1 1928 earthquake is located in the Andes mountain
·The increasing annual emissions of iron ore tailings have proved a great threat to the natural environment and the shortage of natural river sand as well as the pursuit of sustainable development materials provides motivation to reuse iron ore tailings as a fine aggregate in concrete Due to the significantly different properties of iron tailings sand
·Typical underflow solid concentrations have been reported to be 25 55% w/w for oil sand fine tailings Masliyah and Czarnecki 2011 Consortium of Tailings Management Consultants 2012 and 50 70% w/w for other mineral tailings with conventional and high rate thickeners at the lower end and above 65% w/w for high density paste
Hydro cycloning of plant tailings is an often used tool to produce relatively coarse free draining sand cyclone underflow for Tailing Storage Facility TSF embankment construction This paper outlines the available choices and design considerations involved for the minimizat
·The safety of tailings ponds is considered to be one of the greatest environmental challenges in the field of energy and mining engineering Impacted by factors such as rainfall infiltration recycling water dry beach face evaporation tailings sands close to the saturation line in tailings ponds are subject to frequent dry wet DW cycles DW cycles
·Saturated oil sands tailings can be susceptible to static liquefaction if deposited loosely The occurrence of static liquefaction can thus pose a major risk to an oil sands tailings dam This study presents the results of a series of monotonic undrained and drained triaxial compression tests on moist tamped specimens of coarse oil sands tailings
·This paper focuses on the disposal of iron tailings sand ITS and recycled aggregate of inorganic RAI and proposed the ITS plus RAI solid waste treatment methods which uses ITS and RAI
In underflow tailings sand coarse particles diameter mm act as the skeleton and fine particles diameter < mm can fill the gaps among the coarse particles When the content of fine particles in underflow tailings sand increases the dynamic shear
·In order to understand the influence of reinforcement layers on the mechanical properties of tailings sand with mud interlayers tailings sand from a tailings pond in Yunnan were used as the main experimental material and mesh glass fiber was used as the reinforcement material The effects of reinforcement density and reinforcement position on
Variation laws of cement stabilized iron tailings sand mixtures loss of water dry shrinkage strain and temperature shrinkage coefficient have been obtained by the indoor shrinkage test which are compared with cement stabilized gravel Results of test show that its dry shrinkage strain are greater than cement stabilized gravel There is no significant difference of temperature
·The Oil sands tailings ponds are settling ponds that contain the waste byproduct of oil sands extraction and upgrading They are a mix of water sand silt clay unrecovered hydrocarbons and other contaminants The management of tailings ponds is one of the most difficult environmental challenges associated with oil sands and their existence is extremely
The residual compressive strength loss rate at 800 ℃ is 78%; the statistical formula based on the relationship between the residual compressive strength of iron tailings sand concrete and the experienced temperature can provide a reference for the safety
