A team led by Rice University bioscientist Caroline Ajo-Franklin has discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their ...

One of the more intriguing employs bacteria to do the actual extraction of metals. Bioleaching, as this process is called, is an old idea: more than 2,000 years ago, the leaching of metal was seen ...

Bioleaching is a proven technology that uses naturally occurring oxidizing bacteria to extract nickel, cobalt, copper and precious metals from sulfides. Operating at low temperatures with minimal ...

Bioleaching processes have been expanded to use microorganisms for the recovery of metals from ores and wastes. This study introduces Palca mine tailings pond in Peru which turned into acid mine ...

"The microorganisms are then separated using a hybrid membrane separation process and the valuable metals are "sorted" by charge and size using selective filter units. This is preferably done by ...

The high sulphur content of the Haggan deposit prompted Aura to look into bioleaching technologies, where bacteria are used to acidify and oxidise ores. The tests were carried out at the Parker ...

In addition to the researchers, the current study involved a number of other key players in the bioleaching process, which is summarized in the joint technology: bacteria of different species.

The attachment of microorganisms to surfaces and the involved EPS play a pivotal role in biocorrosion/ biodeterioration of materials and bioleaching of various minerals (mainly metal sulfide ores) ...
