UTILIZING CYANIDE RECOVERY TECHNIQUES IN THE CESL GOLD scale leaching of gold alanglovercoza

UTILIZING CYANIDE RECOVERY TECHNIQUES IN THE CESL GOLD SILVER PROCESS By Tom Robinson Teck Resources Limited Canada Presenter and Corresponding Author Tom Robinson Tomrobinson teck ABSTRACT The CESL Gold Silver Process was developed as an important value enhancing technology to recover gold and silver from residues produced from the CESL The cyanide leaching process has been developed very successfully to recover much of the small gold including micron gold from low grade ore however such a process is totally unsatisfactory for a small scale miner because of the toxicity the significant amount of equipment required and the excessive controls over environmental release
