Metal sulfide precipitation: Recent breakthroughs and future outlooks
(MDPI, 2021)
The interest in metal sulfide precipitation has recently increased given its capacity to efficiently
recover several metals and metalloids from different aqueous sources, including wastewaters
and hydrometallurgical ...
Tracking cobalt, REE and gold from a porphyry-type deposit by LA-ICP-MS: a geological approach towards metal-selective mining in tailings
(MDPI, 2020)
High-resolution mineral characterization performed on mine material from a giant porphyry copper deposit shows that critical and precious metals, such as cobalt, lanthanum, gold, silver, and tellurium, are concentrated in ...
Quantum critical metals in 4 − ε dimensions
(American Physical Society, 2014-10)
We study the quantum theory of a Fermi surface coupled to a gapless boson scalar in D = 4 − ε space-time dimensions as a simple model for non-Fermi liquids (NFL) near a quantum phase transition. Our analysis takes into ...
Metallic quantum critical points with finite BCS couplings
(American Physical Society, 2015-11-02)
We study the fate of superconductivity in the vicinity of a class of metallic quantum critical points obtained by coupling a Fermi surface to a critical boson. In such systems there is a competition between the enhanced ...
An evaluation into the potential of biological processing for the removal of metals from sewage sludges
(Crc Press Inc, 1999-01-01)
The use of sewage sludge in agricultural land as a means of sludge disposal and recycling has been shown to be economical and suitable because of the presence of nutrients such as nitrogen and phosphorus. However, municipal ...
