Electrochemical study of the catalytic influence of Sulfolobus metallicus in the bioleaching of chalcopyrite at 70 °C
(Elsevier, 2006)
The catalytic influence of Sulfolobus metallicus in bioleaching of chalcopyrite at 70 °C and pH 1.7 was characterized from studies of anodic dissolution of a chalcopyrite concentrate at constant potential. Experiments were ...
Silver-rich chalcopyrite from the active Cerro Pabellon geothermal system, northern Chile
(MDPI, 2020)
Active subaerial geothermal systems are regarded as modern analogues of low- to
intermediate-sulfidation epithermal Au–Ag deposits, where minor amounts of Cu are mostly present
as chalcopyrite. Although trace element ...
Cooperative action of attached and planktonic cells during bioleaching of chalcopyrite with Sulfolobus metallicus at 70 degrees C
(Elsevier, 2008)
The catalytic influence of Sulfolobus metallicus in the bioleaching of chalcopyrite at 70 degrees C and pH 1.5 was studied in shake flask experiments. Leaching was conducted in an iron-free basal medium with a -80 #+ 120 ...
Comparison of chalcopyrite bioleaching after different microbial enrichment in shake flasks
(2013)
The bioleachings of chalcopyrite ore were
compared after inoculating different cultures enriched from
the original acid mine drainage sample. The results showed
that the higher bioleaching performance was achieved ...
Occurrence and distribution of silver in the world-class Río Blanco Porphyry Cu-Mo deposit, central Chile
(Soc Economic Geologists, 2020)
Porphyry Cu-Mo deposits (PCDs) are the world’s major source of Cu, Mo, and Re and are also a significant
source of Au and Ag. Here we focus on the world-class Río Blanco PCD in the Andes of central Chile, where
Ag is a ...
In situ recovery of copper sulfide ores: Alternative process schemes for bioleaching application
(Elsevier, 2020)
There is a growing interest in exploring the application of bioleaching for treating copper sulfide ores of decreasing grade and located at larger depth by in situ recovery (ISR) for its potential savings in ore extraction, ...
Attachment of Acidithiobacillus ferrooxidans onto different solid substrates and fitting through Langmuir and Freundlich equations
(Springer, 2013)
Attachments of Acidithiobacillus ferrooxidans
ATCC 23270 onto elemental sulfur, quartz and
complex chalcopyrite were investigated by analysis of
its extracellular polymeric substances as well as
applying Langmuir and ...
Geology, geochemistry and mineralogy of the tareek darreh gold deposit, north of torbat-e jaam, northeast iran
(Departamento de Geociencias, 2010)
The Tareek Darreh gold deposit is located 40km north of Torbat-e Jaam in the Khorasan-Razavi province, NE-Iran. The study area is mainly comprised of slightly metamorphosed, sedimentary rocks of Jurassic age including ...
Nanoscale partitioning of Ru, Ir, and Pt in base-metal sulfides from the Caridad chromite deposit, Cuba
(Walter de Gruyter GmbH, 2018)
We report new results of a combined focused ion beam and high-resolution transmission electron
microscopy (FIB/HRTEM) investigation of platinum-group elements (PGE)-rich base-metal sulfides.
The Ni-Fe-Cu base-metal ...
