Panning. Gold panning is mainly a manual gold separation technique from other materials. Large, shallow pans are filled with gold-containing sand and gravel. The pan is submerged and shaken in water, sorting the gravel gold and other material. It quickly settles down to the bottom of the pan as gold is much denser than rock.

In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

What: The challenge of investment in mining. Commodity prices are notoriously cyclical—mining has seen five cycles since 2000. 3 Going forward, we can expect to see similar cyclicity and greater volatility within cycles, as declining ore grades and deteriorating mine conditions cause operating costs to rise and the cost curve to steepen. 4.

Ore containing copper and gold is crushed to a coarse size before the ore is sent to the treatment plant via a conveyor. At the treatment plant, the ore is crushed further and ground finely to slurry. The ore is initially processed by flotation, which produces copper / gold concentrate with between 15% and 20% copper.
