But using fungi on the other hand allows this whole process to be so much more friendly. Finnish scientists from the VTT Technical Research Center have figured a way to filter out gold with biomats made of mycelium - part of a fungi that lives underground.
The researchers say this process recovers 80 percent of the gold, compared to just 10 or 20 percent in the common but toxic chemical processes.
