The accumulation of tailings from gold mining and smelting may result in PTE pollution. We investigated PTE contamination from a large amalgamated gold mine tailings pond in Pinggu County, Mining activities often leave behind a legacy of environmental challenges, with aging tailings ponds representing a significant concern due to their potential for leachate formation and subsequent contaminant release. Thus, this study employs Electrical Resistivity Tomography (ERT) to investigate the intricate pathways of Mapping Leachate Pathways in Aging Mining Tailings Pond

Geochemical Characteristics of Tailings from Typical
With the exploring and developing of mineral resources in the Tibet Autonomous Region for many years, a large number of tailings have been produced. A total of 17 tailings samples from borehole cores This study assesses the feasibility of reusing tailings from a gold mining area in southern Ecuador in concrete block (CB) manufacturing. For this purpose, physical, chemical, and mineralogical analyses were performed to characterize the tailings. Furthermore, the tailing samples were subjected to the European Standard EN 12457-2 Sustainability Free Full-Text Use of Tailings as a MDPI

Emergency Monitoring of a Tailings Pond Leakage Accident
The utilization of mineral resources plays an important role in supporting and promoting economic development and social progress. As a necessary facility for the development and utilization of mineral resources, tailings ponds will cause a series of safety and environmental problems once accidents occur. Based on the Sentinel-2 Mine pollution from mining activities is often widely recognised as a serious threat to public health, with mine solid waste causing problems such as tailings pond accumulation, which is considered the biggest hidden danger. The construction of tailings ponds not only causes land occupation and vegetation damage but also brings Tailings Pond Classification Based on Satellite Images and Machine

Sustainability Free Full-Text In-Pit Disposal of Mine Tailings for
In the next decades many of the old tailings storage facilities (TSFs) could be re-processed if one considers the prices of metals, new uses of metals which today are not valuable, and the application of new, more efficient metallurgical technologies. In this context, in-pit disposal of mine tailings (IPDMT) is an attractive alternative to be used as In mining operations, geotextiles are increasingly being used for building access roads, capping existing tailing facilities, and dewatering tailings and surface water runoffs. There have been many projects worldwide in which geotextile tubes have been used to reduce the slurry volume, increase the strength of tailings, and contain contaminants Dewatering of Mine Tailing Slurries Using Geotextile Tube: Case

Tailings Storage Facilities Sustainability Gold Fields
Tailings are the mineral waste remaining after ore processing to extract mineral concentrates and are typically stored within an engineered containment structure known as a tailing storage facility or TSF. Tailings differ from overburden: the waste rock or material that overlies an ore or mineral body and is displaced unprocessed and stockpiledTailings ponds are one of the three major production facilities in metal mines. The volume of tailings increases year by year, but the storage capacity of existing tailings ponds is limited. Therefore, tailings dams must become more fine-grained and larger. The potential hazard they represent should not be underestimated. This paper Regional Distribution and Causes of Global Mine Tailings Dam
