However, gold is readily dissolved in a number of solvents, including oxidizing solutions of hydrochloric acid and dilute solutions of sodium cyanide. Gold readily dissolves in these solvents because of the formation of complex ions that are very stable. Gold (Au) melts at a temperature of 1,064° C (1,947° F).

Abstract. Gold is considered a store of value and has been a sought-after metal since the dawn of human civilization. It was known to Egyptians as early as 3100 BC. The value of gold was reported to be two-and-one-half times the value of silver in the code of Menes, the founder of the first Egyptian dynasty. A gold mine in Nubia in Nile valley

· Eventually, the hydrogen in the star’s core runs out, and gravity causes the star to collapse. What happens next depends on the star’s mass, but gold is formed when the collapse creates a massive shockwave. During the explosion, a tremendous amount of energy creates heavy elements through the rapid neutron-capture process.

· Pretreatment is required to improve the recovery of gold from refractory gold ore by exposing the gold surface for leaching. Several oxidation pretreatment methods have been proposed. Roasting is the primary method for pretreating refractory gold ores ( Jin et al., 2019 ; Liu et al., 2019 ; Qin, 2021 ).

Gold Mining Operation: 10-30 years. The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold.
