Learn How Gold Bullion is Mined, Refined, and Sold

16-04-2021  Gold is derived from the ground through either placer or lode mining. Placer mining, or panning, is the act of extracting gold from sand or gravel. Think of gold miners squatting alongside rivers, swishing water and sediment around in a circle with a gold pan. The lighter material gets washed away, while the heavier material (gold) stays on the bottom of the pan.

Gold is the most malleable of all metals. It can be drawn into a wire of single-atom width, and then stretched considerably before it breaks. Such nanowires distort via formation, reorientation and migration of dislocations and crystal twins without noticeable hardening. A single gram of gold can be beaten into a sheet of 1 square metre (11 sq ft), and an avoirdupois ounce into 300 square feet
