A company in Leadville wants to truck 1.2 million tons of mining waste to a mill on the edge of town, use cyanide to extract gold and silver from the rocks, then return the hills to a more natural …
A type of green algae known as Chlorella vulgaris has been observed to extract more than 90% of gold from very dilute solution (Hosea et al., 1986; Ting et al., 1995). Moreover, fungal cells such as of those of Aspergillus niger, Mucor rouxii and Rhizopus arrihus, have shown the ability to remove gold (Das, 2010).
