Au Extraction

(OP)
Dear All we are involved in intellectual design of gold extraction facility assuming ore composition gold 8ppm, silver concentrations similar, Cu concentrations close to 100ppm. Assuming ore largely free of sulfides and organics for simplicity and propose to use RIP. As process engineer little solution mining experience unable to find help from literature what are best options for leaching? Is heap leach an option for ore of this grade? Should we agitation leach though higher cost? Any help much appreciated.

But, as this is an exercise, check bookstores at

& local university library.

A very brief intro to gold ore processing:
