The mining industry manages large volumes of tailings, sludge, and residues that represent a huge environmental issue. This fact has prompted research into valorization these wastes as alternative aggregates for concrete production, embankments, pavement material, etc. use resource construction presents two benefits: conserving natural resources reducing the impacts mining. In case road constru...

Contamination of soils, water, and sediments by radionuclides and toxic metals from uranium mill tailings, nuclear fuel manufacturing and nuclear weapons production is a major concern. Studies of the mechanisms of biotransformation of uranium and toxic metals under various microbial process conditions has resulted in the development of two treatment processes: (i) stabilization of uranium and t...

Understanding the characteristic heavy metals and their migration-transformation behavior in mining areas is essential for prevention control of pollution. This study selected a gold mine Anqing-Guichi ore-cluster region Middle-Lower Yangtze metallogenic belt as research area, concentrations, mechanisms metalloid As typical (Cd, Zn, Pb, Cu, Cr, Ni) wastes (mine tailings sewage sludge) surroundi...

OBJECTIVES Asbestos is associated with South African diamond mines due to the nature of kimberlite and the location of the diamond mines in relation to asbestos deposits. Very little is known about the health risks in the diamond mining industry. The objective of this study was to explore the possibility of asbestos exposure during the process of diamond mining. METHODS Scanning electron micr...

Lead (Pb) is one the most paradoxical elements, both having diverse practical uses, as well being extremely toxic to humans, especially children. The use Pb records a steady growth with annual production currently...

Mining often results in the contamination of groundwater by metal, sulphate and radionuclide ions following their percolation from tailings impoundments. This chapter discusses the processes by which elements within tailings are transformed and translocated to groundwater and the role of aquifer characteristics and colloids in these processes. The prevention and remediation of contaminated grou...

Mine tailings from copper mines are considered as one of the sources of highly hazardous acid mine drainage (AMD) due to bio-oxidation of its sulfidic constituents. This study was designed to understand microbial community composition and potential for acid generation using samples from mine tailings of Malanjkhand copper project (MCP), India through 16S rRNA gene based amplicon sequencing appr...
