Gold Ores | SpringerLink

Gold, along with silver and copper, is a member of the IB group of the periodic table, the coinage metals (Table 1-1). Its principal oxidation states are + 1 (aurous) and + 3 (auric). Gold is soluble in cyanide solutions and in aqua regia, forming complexes of the types [Au(CN) 2 ] −, [AuC1 2 ] −, and [AuC1 4 ] − .

Determination of gold in gold ores | SpringerLink

The gold content of placer gold flakes and gold bearing ores has been determined by instrumental neutron activation analysis /INAA/ and radiochemical neutron activation analysis /RNAA/. It was discovered that significant errors result in the instrumental method for gold flakes as small as 10 mg due to sample self-absorption of neutrons during irradiation.

Pressure oxidation

Pressure Oxidation is a process for extracting gold from refractory ore. The most common refractory ores are pyrite and arsenopyrite, which are sulfide ores that trap the gold within them. Refractory ores require pre-treatment before the gold can be adequately extracted.[1] The pressure oxidation process is used to prepare such ores for ...
