Here Is The Correct Way To Effectively Recognize Gold Ore
2022-7-22 Scientists think that gold was originally produced in the universe in supernova nucleosynthesis. They also theorize it was produced by the collision of neutron stars and was present in the dust from which the solar system formed. In the earth, during its molten formation stage, most of the native gold sunk into the core.

gold processing Mining and concentrating Britannica
With ores of higher gold content (i.e., greater than 20 grams of gold per ton of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced.

Scanning-electron-microscope imaging of gold (electrum
2019-12-16 In the 1930s, Jumbo produced approximately 25,000 oz (~ 775 kg) of gold from narrow (< 1 m wide) adularia quartz-electrum veins (Willden 1964 ), but the ores available for this study came from veinlets just a few cm in diameter. Thus, Jumbo ores lack the distinctive multiple electrum-silica banding typical of the Sleeper deposit.
