Enumeration of Acidithiobacillus ferrooxidans adhered to agglomerated ores in bioleaching processes
(2002)
In bioleaching processes, bacteria adhered to agglomerated ores are frequently determined in the washing solution after treating the mineral with different techniques like sonification or chemical treatment with SDS, Tween ...
Slow release boron micronutrients from pelletized borates of the northwest of Argentina
(Pergamon-Elsevier Science Ltd, 2006-04)
The production of slow release boron micronutrients in water for agricultural fertilizers is presented in this paper. Agglomeration, pelletizing and sinterization techniques are appropriate for manufacturing particles whose ...

Activation of bacteria in agglomerated ores by changing the composition of the leaching solution
(ELSEVIER, 2003-10)
This work presents preliminary results of a study to determine the technical feasibility of heap bioleaching of copper sulfides in a mixed ore that had previously undergone a chemical leach to recover the copper from the ...
Behavior and characterization of titanium dioxide and silver nanoparticles in soils
(Elsevier Science, 2016-09)
The presence and transport of emerging Engineered Nano Particles (ENPs) in the environment is driven by combination of multiple factors comprising their size, charge and aggregation/agglomeration rate along with interactions ...

The European Union established that all its countries acquire a national energy action plan aiming at that 20% of the total energy consumed from renewable sources, such as biomass, until 2020. The Republic of Ireland where ...
Mineral-induced bubbling effect and biomineralization as strategies to create highly porous and bioactive scaffolds for dentin tissue engineering
(2022-01-01)
The objective of the study was to assess the biological and mechanical characteristics of chitosan-based scaffolds enriched by mineral phases and biomineralized in simulated body fluid (SBF) as a possible biomaterial for ...
Influence of mineralizer agents on the growth of crystalline CeO 2 nanospheres by the microwave-hydrothermal method
(2013-02-15)
Cystalline ceria (CeO2) nanoparticles have been synthesized by a simple and fast microwave-assisted hydrothermal (MAH) under NaOH, KOH, and NH4OH mineralizers added to a cerium ammonium nitrate aqueous solution. The products ...
