Geoelectrical prospecting for a copper-sulfide mineralization in the Camaqua sedimentary basin, Southern Brazil
(Inst Geophysics Unam, 2016-07-01)
In this paper are presented the results of the combination between a resistivity method and geological surface mapping, applied to the study of an area with potential mineralization of copper sulfides sited on the northern ...
Chalcopyrite and bornite differentially affect protein synthesis in planktonic cells of Acidithiobacillus ferrooxidans
Acidithiobacillus ferrooxidans is used in bioleaching industrial operations to recover metal ions from mineral sulfides. Chalcopyrite and bornite are copper sulfides that have the same elemental composition, but differ in ...
Geoelectrical prospection of disseminated sulfide mineral occurrences in Camaquã Sedimentary Basin, Rio Grande do Sul State, Brazil
The mineral exploration is a complex activity that should involve a combination of direct and indirect techniques of geological investigation. The growing demand for base metals in the national and international market ...

(PERGAMON-ELSEVIER SCIENCE LTD,, 2000)
Aqueous Nanofluids Based on Copper MPA: Synthesis and Characterization
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2017-01-01)
The application and use of efficient cooling fluids have become increasingly important due to the increasing industrial and energy demand associated with the miniaturization of various electronic devices. The search for ...
Biological and chemical control in copper bioleaching processes: When inoculation would be of any benefit?
© 2014 Elsevier B.V. All rights reserved.Bioleaching of secondary and low-grade copper ores in heaps and dumps today is a well-established technology. However, there is still a strong need to improve the copper leaching ...
PHOTOELECTROCHEMICAL CHARACTERIZATION OF NATURAL COPPER SULPHIDE ELECTRODES IN ALKALINE MEDIA: EFFECT OF XANTHATE ADSORPTION

COPPER REMOVAL FROM MOLYBDENITE BY SULFIDATION-LEACHING PROCESS
(JOHN WILEY & SONS INC, 2013)
Molybdenite (MoS2) concentrates are produced by differential flotation from bulk copper-molybdenum concentrates. However, complete separation of molybdenum by flotation is very difficult, thus, molybdenum concentrates ...
