Gold Rocker Box Mineral Processing & Metallurgy

One of the first devices used after the gold pan was the gold rocker box.

Rocker box Wikipedia

A rocker box (also known as a cradle) is a gold mining implement for separating alluvial placer gold from sand and gravel which was used in placer mining in the 19th century. It consists of a high-sided box, which is open on one end and on top, and was placed on rockers. The inside bottom of the box is lined with riffles and usually a carpet (called Miner's Moss) similar to a sluice.
