Twenty‐Year Longitudinal Cohort Study of Cancer Incidence and Mortality Among Workers in Two Primary Aluminum Prebake Smelters

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Classified as carcinogenic to humans by the International Agency for Research on Cancer, aluminum production has been transitioning towards lower polycyclic aromatic hydrocarbon‐emitting prebake smelters. This study explored the risk of cancer and mortality over 20 years follow‐up among a cohort of aluminum prebake smelter workers ...

Reclamation of reactive metal oxides from complex minerals using alkali roasting and leaching- an improved approach to process engineering [PDF]

, 2015
In nature, the commonly occurring reactive metal oxides of titanium, chromium, aluminium, and vanadium often chemically combine with the transition metal oxides such as iron oxides and form complex minerals.

Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

Coarse bauxite residue for roadway construction materials [PDF]

International Journal of Pavement Engineering, 2013
About 25 million tonnes of bauxite residue (BR) from alumina refining are generated in Australia each year. Managing this residue is costly, and the reuse of coarse BRs is becoming an increasingly attractive and sustainable solution to the problem. Using coarse BR in road construction has the potential for large volume reuse.

Usability of clay mixed red mud in Hungarian building material production industry [PDF]

, 2015
The naturally occurring radionuclide (226Ra,232Th and40K) content of building Materials (NORM) contributes to the total radiation dose experienced by humans. In this survey 27 clay and 68 red mud samples were surveyed with gamma spectrometry and screened

Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension
