New Gold Recovery Method
p. 58 · Read in the full issue
A REVOLUTIONARY process enabling the profitable recovery of gold from the lowest-grade ores was described to the convention of the American In stitute of Mining and Metallurgical Engineers in New York early in April.
The new method is based on the dis covery that gold adheres to charcoal rather than being precipitated by it, as previously thought. The process consists of adding activated carbon lime to cyan ide in the grinding mill. The mixture is then agitated, and the gold is finally sep arated from the carbon by a flotation method.
