Phytomining of gold: A review
The uptake of gold by plants has fascinated scientists for over 100 years. Lungwitz (1900) was the first to suggest the analysis of plant tissue for gold to locate the gold deposits. Further research on biogeochemistry of gold and the use of plants as an exploration tool for gold rich deposits was followed in the Soviet Union.
