Estudo da dissolução oxidativa microbiológica de uma complexa amostra mineral contendo pirita (FeS2), pirrotita (Fe 1-XS) e molibdenita (MoS2)
(2007-09-01)
This work aims to study the oxidation of a complex molybdenite mineral which contains pyrite and pyrrotite, by Acidithiobacillus ferrooxidans. This study was performed by respirometric essays and bioleaching in shake flasks. ...

Geophysical prospection in tin mineral occurrence associated to greisen in granite São Sepé (RS)
(Fundação Gorceix, 2018-04-01)
Abstract The discovery of new mineral resources involves various research techniques through direct and indirect studies. The geophysical methods are important tools in the detection of deep deposits because they use the ...
Chalcopyrite and bornite differentially affect protein synthesis in planktonic cells of Acidithiobacillus ferrooxidans
(2007-12-01)
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 ...
