THIOSULPHATE LEACHING AN ALTERNATIVE TO

Thiosulphate leaching is a process that removes gold from gold bearing ores without the use of cyanide. Although not as aggressive a leaching agent as cyanide, thiosulphate offers several technological advantages including its lower toxicity and greater efficiency with gold deposits associated with preg robbing ores. The thiosulphate leaching process, followed by resin in pulp gold extraction, has been developed by SGS to the point where it is a technically and economically viable alternative to cyanidation for some gold bearing
