Feb 29, 2016 · Typically these tests are performed at 80-85% passing 75µm and the ore is leached in slurry form (30-33% solids). The variables to be evaluated are sodium cyanide dosage, pH, leaching time, and oxygen level. For example the program can evaluate 0.5, 1.0, 1.5, 3.0, and 6 gpl of NaCN, the pH can vary from 10.0 to 11.5.

Diagnostic Gold Leach Testing

Jul 15, 2015 · Diagnostic Gold Leach Testing. A Gold Diagnostic Leach Test is used to evaluate the distribution or deportment of gold in various minerals is determined by a series of selective leaches, usually by increasingly stronger oxidative acid leaches. Between each stage, cyanide leaching is used to extract the released gold.
