Sedimentary rocks contain a unique record of the evolution of the Earth system. Deciphering
this record requires a robust understanding of the identity, origin, composition, and post …

The karst bauxites of the Parnassos-Ghiona Unit (Greece) are hosted within Upper Jurassic
to Late Cretaceous carbonate rocks. Three bauxite horizons are intercalated within shallow …

Some belite-ye´ elimite-ferrite (BYF) cements present low mechanical strengths mainly due
to the slow reactivity of belite. A solution to this problem may be the activation of BYF clinkers …

Sulfide ore processing generates finely ground mine tailings that often contain sulfide
minerals such as pyrite, pyrrhotite, arsenopyrite, and gersdorffite. These minerals can …

X-ray diffraction (XRD) analysis, as one of the most powerful methods, has been widely used
to identify and quantify minerals in earth science. How to improve the precision of mineral …

Aeolian dust deposition is an important phosphorus (P) input to terrestrial ecosystems, but its
influence on P dynamics during long-term ecosystem development remains poorly …

The conversion of α-spodumene was performed using two different CO 2/CH 4 thermal
reductive plasma reactors. Using one configuration, particle size was proven to have a major …

Heat-treatment of spodumene concentrate at 1323 K (1050° C) for 30 min in a rotary kiln
yielded a successful decrepitation. Particle size decreased from 2 cm to less than 425 µm for …

Microstructure and thermal stability of high chromium ferritic/martensitic steel 12Cr-2W-2Ni-
0.5 Mo processed by equal channel angular pressing (ECAP) has been investigated using …

This study explains a co-promoting interaction of cerium and barium additives in a cobalt
catalyst used for ammonia synthesis. The results show that a synergistic effect of Ce and Ba …
