PCR-mediated detection of acidophilic, bioleaching-associated bacteria [PDF]

open access: yes, 1997
The detection of acidophilic microorganisms from mining environments by culture methods is time consuming and unreliable. Several PCR approaches were developed to amplify small-subunit rRNA sequences from the DNA of six bacterial phylotypes associated ...

Bacterial leaching of an Indonesian complex copper sulfide ore using an iron-oxidizing indigenous bacterium

open access: yesMicrobiology Indonesia, 2018
The bioleaching of an Indonesian complex copper sulfide ore was studied in shake flasks over a period of 14 days using an iron-oxidizing indigenous bacterium at room temperature (28 oC) and various pulp densities (5% and 20%). The bioleaching suspensions

Electrochemical behaviour of L-cysteine on massive chalcopyrite (CuFeS2) bioleached by leptospirillum ferrooxidans

open access: yesInternational Journal of Electrochemical Science, 2019
This study introduces a mechanism for speeding up the bioleaching process. We examine the effects and kinetics of L-cysteine on the bioleaching of chalcopyrite via Potetiodynamic polarisation, electrochemical impedance spectroscopy (EIS) and cyclic ...

Effects of Bioleaching on the Chemical, Mineralogical and Morphological Properties of Natural and Waste-Derived Alkaline Materials [PDF]

open access: yes, 2012
Bioleaching is a potential route for the valorisation of low value natural and waste alkaline materials. It may serve as a pre-treatment stage to mineral carbonation and sorbent synthesis processes by increasing the surface area and altering the ...

Bioleaching of rare‐earth elements from phosphate rock using Acidithiobacillus ferrooxidans

open access: yesLetters in Applied Microbiology, 2022
Phosphate rock containing rare‐earth elements (REEs) is considered one of the most promising potential secondary sources of REEs, as evidenced by large tonnages of phosphate rock mined annually.

Interrelationship of hydrology, microbial colonisation and hydrometallurgy in a simulated chalcopyrite heap leach [PDF]

open access: yes, 2008
Includes bibliographical references (leaves 104-115).Chalcopyrite is the most abundant primary copper sulphide mineral found worldwide. As copper grades of ores available for extraction decrease, heap bioleaching is gaining interest as a potential ...

Bioleaching of copper- and zinc-bearing ore using consortia of indigenous iron-oxidizing bacteria [PDF]

open access: yes, 2018
Indigenous iron-oxidizing bacteria were isolated on modified selective 9KFe(2+) medium from Baiyin copper mine stope, China. Three distinct acidophilic bacteria were isolated and identified by analyzing the sequences of 16S rRNA gene.
