Prospecting and Mining Gold
The entire process of gold mining can be broken down roughly into four steps: prospecting, mining, extracting and refining. Early discoveries of gold relied on the blind luck of someone spotting a yellow glint in a stream or in a crack between rocks. But the search today is more systematic and precise.

Gold processing
After cooling, the lead "button" is separated from the slag layer and heated under oxidizing conditions to oxidize and eliminate the lead. The shiny metallic bead that is left contains the precious metals. The bead is boiled in nitric acid to dissolve the silver (a process called parting), and the gold residue is weighed.

Gold processing
Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …
