Gold cyanidation Wikipedia

Dec 15, 2003 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 complexIt is the most commonly used leaching process for gold extraction Production of reagents for mineral processing to recover gold, copper, zinc and silver represents Cyanide Process Cyanide process is also called as Macarthurforest Process It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide This process was introduced in the year 1887 by the Scottish chemists naming Robert W Forrest, John S MacArthur, and William ForrestCyanide Process Gold Cyanidation Process Gold Leaching Generally, the gold cyaniding processes mainly include carbon in pulp (CIP process), carbon in leaching (CIL process), pool leaching process and heap leaching process 1 Carbon in pulp (CIP) and carbon in leaching (CIL) The main difference between the CIP process and the CIL process is the order of leaching and adsorptionSummary of Gold Cyaniding Processes XinhaiThe gold ore process is an efficient method of extracting and recovering gold from its ore By cyaniding and carbon leaching crushed gold ore slurry simultaneously, the gold ore process lowers the gold mining operation cost and increases the gold recovery rate to a degree of 99%Gold Mining Equipment Hongji GroupGold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metalCyanide Leaching Of Gold Mine
