The Detrital Versus Authigenic Origin and Provenance of Mineral Particles in Mesozoic Carbonates of Central Croatian Karst Area

Geologia Croatica, 2010
In 1911, Tucan studied the insoluble residue of limestones and dolomites from the Croatian karst realm, and compared it to the composition of terra rossa and bauxite. He concluded that the insoluble residue represented the source material for terra rossa

Improvement of aggregate-associated organic carbon and its stability in bauxite residue by substrate amendment addition [PDF]

, 2020
Bauxite residue has extreme alkalinity, poor aggregate stability, and low organic carbon content, which limits plant growth on large expanses of bauxite residue disposal areas.

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

Can inorganic fertilizer substitute for organic amendments in the rehabilitation of saline, sodic ore refining residues? [PDF]

, 2003
Organic amendments would generally be attractive additions for revegetation of ore refining residues that mostly contain negligible organic matter. However organic materials may not be available on mine sites in sufficient quantities and are bulky to ...
