The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold …
Generally, the ore is crushed into fine particles before being heaped and sprayed with a leaching solution which liquefies and separates the gold from the ore. Our process at Lomati Mine begins with trenches being dug and soil samples being taken at specific intervals within the trenches to test the quality of the ore along that channel.
