DIAMOND MINING AND THE ENVIRONMENT FACT SHEET
Diamond mining uses water, rather than chemicals, for extraction, but of course, water is scarce in many parts of Africa, where diamond mining companies often operate. This makes it even more important that the diamond mining process does not pollute natural water sources and that it uses as little as possible.

Gold Mining Methods Ground Truth Trekking
Placer Mining. The stereotypical grizzled goldrush prospector panning for gold was searching for "placer gold", or gold deposited in a waterway. Placer mining takes a variety of forms, including panning, "sluiceboxing", hydraulic mining, and dredging. All of these techniques use gravity and water to separate the dense gold from the lighter sand and gravel.
