So was wondering if any one could recommend any good books or reading on Cyanide methods with gold or polymetallic ores? Have read C.W. Ammen and searched this forum abit, im fairly comfortable with garage/bootleg inorganic chemistry and the motions and saftey of working with dangerous chemicals but am not a chemist by trade so please nothing super deep, technical/doctorate level. Also correct me if I am wrong but in using a cyanide based leach you are pretty much looking at electrowinning, zinc, or carbon/ash/AR as the three main recovery methods correct?
