This relies on the difference in densities between the ore minerals and the gangue. This method has appliions in various stages of a flowsheet; from initial processing to final upgrading. Some of the earliest methods were utilized by the prospectors of the gold rush where they used simple panning techiniques to concenrate their ore. Thoughrudimentary, it is still an applicable process .

The principal gold minerals that affect the processing of gold ores are native gold, electrum, AuAg tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the AuAg tellurides, and very finegrained gold (<10 µm) locked ...
Indonesia is the largest exporter of nickel ore and tin in the world and ranks among the biggest for copper and gold production. To add value to these minerals, Indonesia imposed an export ban which has recently been relaxed due to private sector pushback and falling revenues. While the shortterm costs of the ban are apparent, the longterm
gold recovery. However, cyanidation after dissolving the ore sample in hydrochloric acid (HCl), sulfuric acid (H 2 SO 4), ferric chloride (FeCl 3) and nitric acid (HNO 3), respectively, increased the gold recovery to %. This shows that the ore is a sulfide refractory gold ore (Saba et al., 2011).
