TEXT FILE:
Pure gold is a soft, dense, yellow metal with a specific gravity of 19.32 and a melting point of 106°C.
In the natural environment, gold is invariably alloyed with silver or copper.
Native gold commonly contains approximately 85–95% gold with the balance typically as silver.
Gold containing at least 20% silver is called electrum.
Gold is also associated with telluride.
Gold tellurides were discovered in Kalgoorlie in June 1896, an event recorded on a plaque at the KCGM superpit lookout.
Vein gold is commonly associated with sulfide.
