Leaching | Hazen Research

The leaching process may employ one of a variety of chemicals such as dilute sulfuric acid, dilute aqueous cyanide, or other reagents. Methods for contacting ore and solution include agitating ground solids and solution (slurry) in open tanks, agitating slurry at a high temperature in a pressure vessel, or percolating solution through crushed ore that has been piled in a heap

What is Gold Cyanidation? (with picture)

The cyanidation process begins after the gold has been discovered and the raw ore separated from the ground, often by explosive means. The ore is ground up to better facilitate the leaching process. Breaking up the ore into finer pieces is called heap leaching. Processing the ore immediately without crushing it is known as dump leaching.
