Background: Fluoride plays an important role in bone and dentin mineralization; however, excess fluoride intake is harmful to mankind. Methods: This study evaluated the performance of bauxite from active Iranian mines in removing fluoride from drinking water. The effects of pH, contact time, adsorbent dose, and fluoride concentration on defluoridation and removal efficiency were determined. Ki...
The Qopi bauxitic horizon is located west of Miandoab, in West-Azarbaidjan province, NW of Iran. It lies along the boundary of Ruteh (middle-upper Permian) and Elika (lower Triassic) Formations. This horizon includes four distinct lithologic facies such as (1) bauxitic iron ore, (2) ferruginous bauxite, (3) Fe-rich bauxite, and (4) Fe-rich clayey bauxite. Microscopic examinations showed variou...
Cu/Ba/bauxite possesses superior NOx storage and reduction (NSR) performances, high thermal stability, strong resistance against SO₂ poisoning and outstanding regeneration ability in comparison with Pt/Ba/Al₂O₃. It can serve as a cheap and promising alternative for traditional Pt/Ba/Al₂O₃ in NOx removal from lean-burn engines.
Sampling is an important tool for gathering information about mineral deposits, helping to estimate the ore grade, and has great relevance at any stage of a mining project, ensure reliable results consequently, project better planning. There are several errors which sampling exposed among them we can mention fundamental error (FSE). This cannot become zero as it related constitutional heterogen...
