Gold and Silver Metallurgy Technology

An ore may be treated experimentally with cyanide solution and 90 per cent, of the gold or silver dissolved. This may be quoted as an ex­traction of 90 per cent., but it is preferable not to do so, since it is, at best, only an experimental extraction; and by no parallel method of operation in practice could such an “extraction” be actually realized as a recovery. The percentage obviously
