In this research, optimization of effective parameters for increasing gold recovery in Cyanidation process was carried out on HamzehQarnein gold ore containing ppm gold. Accordingly, the effect of parameters such as particle size (d 80), pH,
The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even impossible. Extractions are low and the solutions soon become ''foul.'' The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected.

The Refractory Gold Containing Sulfide Ores are characterized by complex structure, by extremely thin impregnation of gold in sulfide ores (so called fineparticle gold with particle size from 1 to 5 micrometer), and by presence of components, which decrease the extraction of gold under cyanidation.
containing aurostibite. For the treatment of high grade silvergold ores (> 100 g/t Ag) efficient cyanidation of high grade silvergold ores (> 100 g/t Ag) was possible with only 500 ppm NaCN.

Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.
The leaching parameters were 800 ppm NaCN, DO 16 ppm and pH for a duration of 120 hours. The associated cyanide consumption was kg/t. Gold leaching was not sensitive to cyanide concentration. Reducing the cyanide concentration to 250 ppm resulted in a gold extraction of % with a cyanide consumption of kg/t.
