"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.

“In bioleaching we use bugs.. those are bacteria that break down the sulphides and release the copper,” Laing said. “It’s incredibly valuable if you can get it right, but it’s not so easy getting it ...

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) ...
