Placer Mining Methods PLACER GOLD RECOVERY METHODS

With placer mining, recovery of the gold from the ore is usually the most expensive phase of the mining operation and can be the most difficult to implement properly. The value of gold deposits is based on the amount of gold that can be re-covered by existing technology. Failure to recover a high per-

Placer deposits are masses of gravel or other residual or detrital material that contain one or more valuable minerals that have been concentrated by weathering and mechanical processes. The concentrated minerals are, therefore, resistant to weathering and abrasion, and are typically of greater specific gravity, 3.3–22, than the most common minerals, which have specific gravities of about 2 ...
