Gold solubility in the common gold-bearing minerals ...

1999-12-1  A method is proposed for determining gold solubility in the common gold-bearing minerals (sulfides, etc.) using so-called "gold-assisting elements" (GAE). These elements increase gold solubility in the fluid phase, enabling minerals formed from hydrothermal fluids to be saturated with gold.

8 Types of Gold Ore- Properties and Ways to Process

2021-10-28  Properties of tellurium gold ore Gold-bearing minerals containing tellurium are called "tellurides". Tellurium–gold deposits differ from normal gold mineralization in their significant content of tellurium‐bearing minerals with a close relation between Au and Te.

Calaverite (gold telluride) Western Australian Museum

2021-5-10  The gold-bearing minerals that contain tellurium are called ‘tellurides’. The Golden Mile deposit in Kalgoorlie, Western Australia, is a massive deposit containing greater than 1500 tonnes of gold. Some 70 to 75% of gold in the deposit occurs as native gold, but a further 20% occurs as tellurides.

Prospecting Placer Gold Deposits

2017-3-20  Prospecting for placer gold, except perhaps in the case of buried placers, is the simplest form of prospecting. Gold, platinum, and tin are the principal metallic minerals won from placers, but gold (alloyed with varying percentages of silver) is the only metal that has been recovered in commercially important quantities from placers in the United States.
