Weathering of sulphide minerals produces a large variety of Fe-oxide-bearing ochreous,
varicoloured precipitates and efflorescences of variably soluble sulphate salts. These …

The manganese ore of Praborna (Italian Western Alps) is embedded within a
metasedimentary sequence belonging to a subduction mélange equilibrated at high …

Mining waste residues from the abandoned Pefka polymetallic epithermal deposit
(northeastern Greece) were studied to document the products of sulfide oxidation and to …

Understanding water circulation in rocks represents a very important element to solving
many of the problems linked with civil, environmental and mining engineering. This book …

The efficacy of Zn–Al sulphate layered double hydroxides (LDHs) in removing molybdenum
from aqueous solution was tested through sorption of aqueous molybdate by synthetic …

We have recently discovered significant amounts of zaccagnaite, a natural Zn-Al-CO3
hydrotalcite in the El Soplao cave (north Spain). The El Soplao zaccagnaite is speleothemic …

Ethanol has been used as a renewable hydrogen‐donor in the conversion of a lignin model
molecule in subcritical conditions. Noble metal‐free porous mixed oxides, obtained by …

The adequacy of synthetic Zn–Al-sulphate LDHs to remove arsenic from aqueous systems
was tested through sorption experiments, using a series of aqueous solutions with dissolved …

Heavy metals contained in wastewater are generally removed by adding antalkaline to
increase the pH, and Ni is commonly precipitated as Ni-hydroxides at pH 10. However, a …

The results of a complex investigation of the sulphate and arsenate assemblages forming in
the weathering zone of selected ore deposits in the Sudetes are presented. The …
