Mining: The Hard Rock Mining Process

Before hard rock mining operations have even begun, companies explore areas where gold may be found and scientifically analyse the rock. The actual gold originates deep within the earth in places called pockets. These pockets are filled with gold, heavy ore, and quartz.

Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and
