A Poor Man's Method of Smelting Gold Sciencing

May 22, 2018· You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.

Gold processing Mining and concentrating Britannica

Gold processing Gold processing Mining and concentrating: 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 piled into heaps for
