Studies regarding how environmental risk evolves in abandoned mining areas in the medium term have been seldom carried out. The answer to this question is not obvious despite it is essential in order to evaluate the need to take urgent control measures in these areas. Fifty-two samples corresponding to soils (from natural pasture and arable lands)...

A sepiolite mining by-product (SEP) has been studied as major component for lightweight aggregate (LWA) manufacture. Pellet bursting during firing was avoided by the addition of 2.5 wt% of thermoplastic waste (P) and 2.5 wt% P + 2.5 wt% carbon fiber residue (FC) in powder form. The mixtures were pelletized and then sintered at 1225˚C for 4 minutes...

The suitability of three new lightweight aggregates containing carbon fiber residues (CAs) as components in structural lightweight concrete has been studied. Prismatic concrete specimens were prepared using these CAs as a coarse fraction. Additional specimens of normal-weight aggregate, commercial lightweight aggregate and mortar were prepared for...
Article
Mining activity can release important amounts of toxic metals which are able to move through the soil, water and air, or even to reach the human food chain. Consequently, the environmental and health issue related to ore extraction has led to an increased awareness of the importance of recovering mining sites. In this study, samples taken from tail...
Article
Twelve selected aggregates sintered from granite-marble-sepiolite wastes containing different proportions of powdered carbon fiber (FC) and thermoplastic (P) were studied by Rietveld X-ray diffraction, microscopy and thermal techniques to assess the influence of heating temperature (1100, 1125 or 1150 °C), dwell time (4, 8 or 16 min) and additive o...
Article
Three different wastes have been assessed for lightweight aggregate (LWA) manufacturing: granite and marble sludge (COR), sepiolite rejections (SEP) and polyethylene-hexene thermoplastics (P). A preliminary study of the physical and chemical properties of the raw materials was carried out to design proper batches. It was mixed 10% SEP with 90% COR...

Abbreviations: BCR-SEP: optimized BCR sequential extraction procedure; b.d.l: below the detection limit; F1: weakly adsorbed, exchangeable and water- and acid- soluble fraction; F2: reducible fraction; F3: oxidable fraction; F4: residual fraction; HM: heavy metal; ICP-MS: inductively coupled plasma-mass spectroscopy; LOI: loss on ignition; LWA: li...
Article
Washing aggregate sludge (WAS) from a gravel pit and sewage sludge (SS) from a wastewater treatment plant (WWTP) were analysed in terms of their physical, mineral and chemical characteristics. Both waste materials were mixed, milled and made into granules, pre-heated for 2 and 5 min and sintered in a rotary kiln at temperatures between 1175 °C and...
Article
This work is aimed to the establishment of some clues concerning metal uptake by the holm oak (Quercus ilex L.) in abandoned base metals (Pb-Zn) mining sites from central Spain. The study is based on total contents of potentially harmful elements (PHEs), including Pb, Zn, Cu, As, Sb, Cd and Hg, in leaves from holm-oak trees as well as in the corres...
Article
The effects of the prefiring and firing dwell times on the chemical, physical and microstructural properties of artificial lightweight aggregates (LWAs) produced from mining and industrial waste with a tubular rotary kiln were determined. It was observed that 1.5 and 3 min of prefiring and firing dwell times, respectively, were more adequate than 5...
Article
The chemical extraction of twenty-nine elements in a washing aggregate sludge, a clay-rich sediment, a sewage sludge, the mixtures of these materials and the artificial lightweight aggregates (LWAs) manufactured with them was determined by applying the optimized European Community Bureau of Reference sequential extraction procedure in order to esta...

Ojailén Valley is situated in South Central of Spain, an area where livestock, agriculture, mining and industry coexist. This work tries to assess the relationships between these activities and local environmental compartments: water, soils and heavy metal contents, and establish the most appropriate methodology of sample treatment and analytical t...
Conference Paper
Full-text available
Alcudia Valley is a vast territory recently declared Natural Park, located in South of Spain. It is an area rich in mineral deposits of Zn and Pb and mining exists since the first millennium BC., having its highest ore production between mid-nineteenth century and the middle of the twentieth. This area has been selected because has more than 120 ab...

This paper presents a study about the effectiveness of thermal treatment in the immobilization of different chemical elements within the structure of artificial lightweight aggregates (LWAs) manufactured with contaminated mine soil and fly ash. The heat treatment was totally effective in the immobilization of Cr, Ni, Cu, Zn, Pb, Be, Mn, Co and most...

The optimized BCR sequential extraction procedure was applied to washing aggregate sludge and fly ash, the raw materials used to produce artificial lightweight aggregates (LWAs) in a previous study. The mixtures of the raw materials and the two types of LWAs obtained have also undergone this procedure. As a result, it has been possible to evaluate...

Los yacimientos de mercurio del Distrito minero de Almadén representan una singularidad mundial, al ser el único caso de un metal, el mercurio (Hg), que ha sido obtenido en una tercera parte de su producción mundial a partir de un solo yacimiento. El Distrito está formado por una serie de yacimientos de cinabrio (HgS), entre los que la mina de Alma...

The fractionation of five heavy metals in a washing aggregate sludge, a sewage sludge, a clay-rich sediment, the mixtures of these materials and the lightweight aggregates manufactured with them has been determined by applying the optimized European Community Bureau of Reference sequential extraction procedure in order to evaluate the effects of th...
Article
The microstructure and mineralogy of lightweight aggregates manufactured with washing aggregate sludge, sewage sludge and a clay-rich sediment have been studied. The mineralogical analysis revealed the neo-formation of plagioclase and pyroxene group minerals and a minor presence of gehlenite. Some relationships may be established: (i) heating tempe...
Article
The microstructures and mineralogical compositions of lightweight aggregates (LWAs) manufactured with washing aggregate sludge (WS), fly ash (FA) and used motor oil (UMO) have been studied. Most LWAs with WS and FA exhibited an external layer and a glassy core with isolated pores. LWAs with WS and UMO did not present external shells or signs of blo...

Washing aggregate sludge from a gravel pit, fly ash of the Aliaga thermal power plant (Teruel, Spain) and used motor oil from cars have been physically, chemically and mineralogically characterized. They were mixed, milled and formed into pellets, pre-heated for 5 min and sintered in a rotary kiln at 1150 °C, 1175 °C, 1200 °C and 1225 °C for 10 min...

Increasing generation of wastes is one of the main environmental problems in industrialised countries. Heat treatment at high temperatures can convert some types of wastes into ceramic products with a wide range of microstructural features and properties (Bethanis et al., 2004). A lightweight aggregate (LWA) is a granular material with a bulk densi...

Pollution caused in soil and surface and groundwater by waste from mining activities is among the main environmental concerns at the Spanish, European and global levels. Between the different types of mining, metal mining is especially worrisome due to the dispersion of toxic metals such as Pb, Cd, Zn, As, Cu, etc. and the generation, from the oxidation of the pyrite waste, of the so-called acidic mine drainage (AMD). The E-BIORE2MIN Project proposes an innovative and sustainable approach to the solution of the environmental problem considered, since its objective is the development of novel combinations of biological and electrochemical technologies for the treatment of mine tailings (fine-grained mine waste) and AMD, focusing on the recovery of the resources contained therein, including metals and/or rare earth elements, reclaimed water, biomass and/or energy; that is, in line with the circular economy concept.
