Placer Gold Dry Washer

Perhaps the most widely used dry recovery technique is dry washing, using a dry washer. The dry washer is basically a short, waterless sluice. It separates gold from sand by pulsations of air through a porous medium. Screened gravel passes down an inclined riffle box with cross riffles. The bottom of the box consists of canvas or some other fabric.

A basic dry washer is composed of a frame in which a wellbraced, heavy screen is covered with burlap overlain with window or fly screen and covered with fine linen. In operation, dry ore is fed into the vibrating screen of the dry washer where the fines fall through to the riffles and the oversize falls off the edge. The bellows and screen are operated by hand cranking or powered by a small engine.

Portable Gold Panning Plant

The simplest technique to extract gold from placer ore is panning. In panning, some mined ore is placed in a large metal or plastic pan, combined with a generous amount of water, and agitated so that the gold particles, being of higher density than the other material, settle to the bottom of the pan. The lighter gangue material such as sand, mud and gravel are then washed over the side of the pan, leaving the gold behind. Once a placer deposit is located by gold panning, the miner usually shifts to equipment that can treat volumes of sand and gravel more quickly and efficiently.
