this paper reviews a series of alternative lixiviant systems for the recovery of gold from ores and concentrates. for over 100 years, cyanide has been the leach reagent of choice in gold mining the gold mining process. In addition to cyanide processing, gold ore is also processed with gravity separation. advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. for example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed to 2770 metric since valuable metals such as copper and gold can also be found in sulfide mineral deposits, mining exploration companies will often look for soil and water with a naturally high arsenic content as a means of locating an ore body.
