What is gold method of extraction? - Heimduo
What is the best method for extracting gold from ore? But, the most efficient method for gold extraction is froth flotation. Along with mechanized mining, froth flotation allowed the best recovery of gold from much lower grade ore than before - making it perhaps the most important mining industry innovation of the 20th century.
