“…The mineralizations were discovered in 1842, and the exploitation of the polymetallic deposits (with 20% Zn and 15% Pb average content) started in 1950. After the independence of Algeria in 1962, SONAREM (Société Nationale de Recherches et d'Exploitation Minières) undertook a prospection campaign in 1967, while the exploitation continued until 1975, when the main mineralizations were exhausted [20]. In 1975 an extensive barite body (850 m in length) was discovered, and currently, barite mining is still active in various underground mines (Sidi Lakhdar, North, Sidi Belabbes, Colonne 2, Belkheiret, Ammal, Sidi Diaber, and Sidi Ouadah).…”

The barite and Pb-Zn (Fe, Cu, and F) ore deposits of Bou Caïd are of the veinand karst-type [20,21]; the main orebodies are at Sidi Ouadah, Sidi Omar, Ammal, and Sidi Djaber, in the massif of Srâa Abd El Kader and in the massif of Grand Pic (Figures 2 and 3).

The ore deposits of Bou Caïd (Ouarsenis, Algeria) occur in Jurassic and Cretaceous sedimentary rocks. The barite and Pb-Zn (Fe, Cu, and F) ore deposits of Bou Caïd belong to vein- and karst-type. The mineralization is represented in the whole area by a mixture of barite (currently still exploited) and nonsulfides consisting of hemimorphite, smithsonite, cerussite, hydrozincite, and Fe-oxy-hydroxides, with remnants of galena and sphalerite in variable proportions. Mineralogical and geochemical analyses were carried out on the Bou Caïd nonsulfides. Several samples representing nonsulfide mineralization (Grand Pic and at Srâa Abdelkader) were subjected to a multidisciplinary analytical approach, using optical microscopy (OM), powder X-ray diffraction (PXRD), Scanning Electron Microscopy with Energy Dispersive Spectrometry (SEM-EDS). Nonsulfide mineralization consists of a mixture of hemimorphite, hydrozincite, smithsonite, cerussite, and Fe-oxy-hydroxides, often with zebra-like textures. In the proposed paragenetic scheme, covellite and chalcocite are followed by cerussite, jarosite, smithsonite, and hydrozincite. Then, hemimorphite crystallizes, accompanied by mimetite, traces of malachite and clay minerals (also Zn-bearing), precipitate. Fe-(Mn)-oxy-hydroxides can form during various phases of the supergene stage. Small amounts of late barite can be related to partial remobilization and occur as reprecipitation products. Stable isotope analyses were performed on the calcites and metal carbonates of the supergene ores. Carbon and oxygen isotope values of smithsonite and hydrozincite were comparable to published supergene Zn carbonate data. The isotope values of the Bou Caïd calcites fell both into the hydrothermal carbonate and in the supergene fields.

“…Following the studies conducted by [5], it has been found that mining waste from abandoned barite mines leads to water contamination with very high concentra tions of heavy metals such as arsenic, barium, iron, mercury, manganese, nickel, lead, and zinc. The studies carried out by [3,6], on the pollution assessment of the mining region of Ain Azel, and the region of Boucaid showed that the enrichment of polymetallic ore is the potential source of soil contamination by heavy metals, whose concentrations of metals in the sedi ments were high: 94.79 of Pb, 89.79 of Zn, 21.73 of Cu, 21.46 of Cr, 3.25 of Cd and 44190 of Fe (mg/kg).…”

Purpose. To study the dielectric properties of porcelain obtained from a mixture of sand, kaolin, and feldspar. The latter has been partially substituted with solid barite wastes (SBWs). Methodology. The study involves preparation of porcelain using conventional solid-state reaction methods, employing two firing temperatures (1200 and 1300 °C) and a soaking time of 3 hours. SBWs are progressively added to the mixtures at levels of 0, 10, 20 and 30 wt%, replacing feldspar content. Structural and dielectric characterizations are conducted to examine the influence of SBWs substitution on macroscopic dielectric properties. Microstructural observations reveal various crystalline phases and micropores, contributing to property effects. Following sintering at 1200 °C, primary mineralogical phases include mullite, anorthite, and quartz. At 1300 °C, the celsian phase emerges alongside anorthite and quartz phases. The technological attributes of the produced porcelain samples, encompassing dilatometric properties, apparent density, and porosity, are determined. Findings. Dielectric characterization, conducted within the frequency range of 102–105 Hz, demonstrates that the relative constant permittivity values rise from 4.3 to 7.4 for samples sintered at 1200 °C and from 5.1 to 9.9 for those fired at 1300 °C, specifically for samples containing 10 wt% SBWs. Additionally, the dielectric loss tangent decreases with increasing sintering temperature. The macroscopic permittivity of porcelains can be accurately calculated using a mixing rule, which aligns well with experimental results. Originality. The original contribution lies in the use of 10 wt% Solid Barite Wastes (SBWs) from the Boucaid mine in order to effectively create environmentally friendly porcelain insulators. The study showcases the potential of SBWs as a partial substitute, thus promoting sustainability in porcelain insulator production. Practical value. The results of this study hold practical significance for the ceramics and insulator manufacturing industries by providing insights into enhancing the dielectric properties of porcelain through the incorporation of SBWs. This approach contributes to the production of environmentally friendly insulators.

“…Many researchers have found that there is a strong correlation between the concentration of heavy metals and magnetic parameters through studying the soil near factories, the soil near roads and other sediments contaminated by various heavy metals [9,10]. Traditional methods of geochemical studies usually take a long time and involve complicated procedures and high costs, while environmental magnetism provides a simple, economical, rapid and non-destructive method that is useful to soil pollution monitoring [11][12][13]. Analysis of magnetic susceptibility of soil shows that some magnetic minerals in soil are produced by human activities such as vehicle emissions, and that magnetic susceptibility of topsoil is higher than that of deep soil [14,15].…”

The magnetic characteristics and heavy metal elements of surface soil samples in Baoji urban street greenbelts were systematically analyzed in order to explore the feasibility of using magnetic parameters to indicate heavy metal pollution in urban street greenbelts soil. The results of the study showed that ferromagnetic minerals with low-coercivity and coarse magnetic grains dominated magnetic properties of the samples. The average values of low-frequency magnetic susceptibility (χ lf ) was 200.65×10 -8 m 3 /kg, which was much higher than the background value. The spatial variation of magnetic mineral content was remarkable, with high levels observed in heavy traffic areas and industrial gathering areas, and low content in areas heavily covered by short vegetation, which was basically consistent delineated by pollution load index (PLI). Magnetic parameters χ lf , saturated isothermal remanent magnetization (SIRM) and soft remanent magnetization (SOFT) can be used as the effective indicators for monitoring heavy metals pollution in soil of urban street greenbelts.
