Pilot-scale heap-leach tests may be conducted on a tonnage scale if it is desirable to confirm results obtained in laboratory column-percolation tests, or to further quantify reagent requirements (fig. 2). ... or deposits too small to justify construction of milling facilities. Although the process is analogous to heap leaching of copper ores ...
The use of "chanchas" is beneficial since no additional investment in equipment is necessary to convert to ... a very poor result when compared with the cyanidation test, when 93% of the gold was extracted after 6 h of mill-leaching process. This indicates that the artisanal gold miners from Talawaan can easily increase their …
