Precipitation/Bioaccumulation of gold is the precipitation of fine-grained gold colloids by microbial activities.
Nugget. A natural gold grain (>5 mm, >200 mg).
The impact of the use of microbial activity for the solution and precipitation of gold was undervalued for a long period, thus affording the opportunity for economic and environmentally friendly gold bio-processing. Furthermore, the current high price of gold has led to intensive research into the precipitation of gold.
