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

Gold Processing AppNote XRT1336: Gold Processing Background Gold ore processors commonly utilize the cyanide leaching technique to recover trace gold content. After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), or Carbon Column CC).
