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.

In this condition, the best gold’s recovery rate may reduce silver.The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
