Because of the uniqueness geological mineralization, tailings obtained from Chenchao Iron Mine have low SiO2 content only 27.80%. Content Al2O3 and MgO is 13.31% CaSO4 22.09%. The fineness modulus ores large enough for convenient mineral separation, thus resulting in 16.03% −5 μm particles 27.76% −10 tailings, respectively. average particle size 69.36 μm; it belongs to category very fine tailin...

Mining activities have been carried out for thousands of years and nowadays have an enormous worldwide use to obtain important metals of industrial use. These include copper, iron, gold and several others. Although modern mining companies have sustainable mining programs that include tailings management and external verifications, it is recognized that these industrial activities are responsibl...

The Certej basin is situated in the North of Deva town, in Apuseni Mountains and was an important nonferrous mining region. In present the mining activities were stopped, but the acid mine drainage is still affecting the underground water quality. Acid Mine Drainage takes place where sulphide-bearing material is exposed to oxygen and water. This drainage water is characterized by low pH, high s...

Cultivation-based and molecular approaches were used to characterize the phylogenetic composition and structure of the microbial community in an extremely acidic (pH 2.0) acid mine drainage (AMD) associated with Pb/Zn mine tailings that were undergoing vigorous acid generation. Acidophilic bacteria were isolated and enumerated on solid media, and were found to be restricted to isolates related ...

In 1998, the Aznalcóllar mine tailings dyke in southwestern Spain broke, flooding the Agrio-Guadiamar river system with acid tailings up to the borders of one of the largest breeding colonies of white storks in the western Palearctic, Dehesa de Abajo. Over the following years, a high proportion of nestlings developed leg defects not seen before the spill, prompting this study. Nestlings with de...

The mining industry produces significant amounts of waste materials, with the greatest volumes generated during enrichment. These materials or by-products, tailings, may be used as alternative civil engineering reducing need for natural resources. In cold climates, frost behaviour is one critical functional requirement in applications. tailings classified sand, silty sandy clayey silt (EN ISO),...
