Gold From Slag Using Bacteria

15-04-2015· Removal of vanadium from Linz-Donawits (LD) converter slag was investigated by means of three different species of microbial systems: Acidithiobacillus thiooxidans (autotrophic bacteria), Pseudomonas putida (heterotrophic bacteria) and Aspergillus niger (fungi).

This study was undertaken to determine the leaching of Cu and Zn from a smelter slag in acidic, sulfate-rich solutions with, and without, mesophilic Fe-and S-oxidizing bacteria. Cu in the slag was mostly distributed in fayalite, Fe-deficient Cu-sulfides and metallic Cu, and Zn was associated with fayalite, magnetite and glassy silicates. The test culture was enriched from acid mine water using ...

On the way bacteria can dissolve and re-concentrate gold — this process removes most of the silver and forms gold nuggets. “We’ve known that this process takes place, but for the first time we’ve been able to show that this transformation takes place in just years to decades — that’s a blink of an eye in terms of geological time.

Award-winning gold recovery with bacteria. A team of students from Heidelberg University that took part in the international iGEM competition in 2013 have developed a method for the recycling of gold from electronic waste by way of biomineralisation assisted with a bacterial peptide.

It is known that many of the gold and silver deposits are often associated with sulfide minerals, specially pyrite. Some of the precious metals in such ores are often found as very finely disseminated particles inside the sulfide crystals. The encapsulation of the precious metals particles in this manner makes their extraction very difficult, as these metals become inaccessible to leaching ...

In order to precipitate the gold from the solution, they use the skills of specially adapted bacteria. The microbe is called Delftia acidovorans which grows only on gold mines. The microorganism has adapted to the environment except by dissolves the precious metal of relatively low concentration solutions of gold.
