Microbial diversity in engineered haloalkaline environments shaped by shared geochemical rrivers observed in natural analogues [PDF]
, 2015 Microbial communities in engineered terrestrial haloalkaline environments have been poorly characterized relative to their natural counterparts and are geologically recent in formation, offering opportunities to explore microbial diversity and assembly ...

Induced shear in reinforced concrete beams with synthetic aggregate
Revista IBRACON de Estruturas e Materiais, 2023 The increasing aluminum production demands larger volumes of bauxite residue (BR) to be stored in the Amazon region. There are millions of tons of waste without reuse but with high potential for use in civil construction as artifacts or components for ...

Iron electrowinning from bauxite residue
, 2019 Η παραγωγή πρωτόχυτου σιδήρου βασίζεται στην ανθρακοθερμική αναγωγή των μεταλλευμάτων του σε θερμοκρασίες άνω των 14000C, παράγοντας μεγάλες ποσότητες καυσαερίων τα οποία περιέχουν διοξείδιο του άνθρακα (CO2). Στα πλαίσια της μείωσης των εκπομπών του διοξειδίου του άνθρακα (CO2) κατά την παραγωγή του πρωτόχυτου σιδήρου, αναπτύσσεται η τεχνολογία ...

Use of inorganic fertiliser in place of poultry manure for rehabilitation of gold and bauxite ore refining residues [PDF]
, 2000 Ore refining residues are difficult substrates for revegetation because they often contain extremely low plant available levels of one or more essential elements (Hossner and Hons 1992).
