Jun 20, 2011· Panning gold was slow work and very early in 1848 Isaac Humphrey, a miner who’d been at the gold finds in the mountains of Georgia in the 1830’s, introduced a new device that sped things up a great deal. Called a rocker or a cradle, it resembled a baby’s bed. At the upper end was a hopper with moderately high sides and covered with a sheet metal or rawhide sieve with holes a half-inch in
Feb 04, 2016· Using a standard sluice box is a great way to find gold. They are simple, lightweight, and can be used in most creeks and rivers to separate fine gold from sand and gravel. Most commercially-made sluice boxes are very good at catching and holding gold, but a
Jun 03, 2018· Like a sluice box, the cradle has riffles and a carpet for trapping the gold. Rocker, probably invented by Cornish miners, was one of the tools used to easily extract gold from rocks and riverbeds during the California Gold Rush. Isaac Humphrey, generally known as "Major" is said to have introduced the rocker to the California gold fields.
Interested in using a simple sluice box to find gold? This is my page of information on placer mining for gold with a sluice. It is a close cousin to the rocker box. It is simply a short sluice with a bottom of one by 12 inch lumber, with 6-inch-high sides and a 1 to 1-1/2 inch end piece. To catch gold, the bottom of the box is covered with
One of the first devices used after the gold pan was the gold rocker box. The rocker allowed small operators to increase the amount of gravel handled in a shift, with a minimum investment in equipment. Rockers vary in size, shape, and general construction, depending upon available construction materials, size of gold recovered, and the builder’s mining experience. Gold Rocker Boxes generally
Locating the richest gold bearing areas primarily involves research, planning, dedication and funds. In other words, those who study geological surveys, land formations, rock structures and gold prospecting history prior to prospecting may have a better chance of finding desired amounts of gold. (See References 1 and 3.)

Tons of free gold panning and gold prospecting tips and tricks of the mining trade. Look below for guides on getting started in gold panning, metal detecting for gold nuggets, finding placer gold in a river, how to corectly use a sluice, and setting up a new suction dredge.
The rocker is used for the same type of work as the gold pan in that it is mainly a prospecting tool. A man is able to wash 3 to 5 times more yardage than with the gold pan, and the use of the rocker eliminates much of the backbreaking strain of continuous panning. On the other hand, the easy mobility of the pan as a prospecting device is lost.
To find a lot of gold, you have to pan a lot of dirt. Panning is not a good method for separating the gold from a lot of dirt. It takes too long and is far too much work. There are other methods besides panning to separate gold from dirt though. A sluice is a device that separates gold from dirt using
Isaac Humphrey is said to have introduced the rocker, or cradle, to the California gold fields as well. A rocker was simply a rectangular wooden box, set at a downward angle and mounted on a rocking mechanism, usually like the rockers on a rocking chair. At the top was a sieve, and at the bottom was a series of cleats, or “riffles.” The
After many shovel loads of gravel were pushed through the rocker, the miner would then use his gold pan to sort out the heavy minerals and, with luck, find gold. The long tom was similar in theory to the rocker but was much more elaborate. A paddlewheel ensured a constant source of water. Again gravel was shoveled into the top end and the water

Roller rockers are constructed of both aluminum and steel. While steel roller rockers may weigh more than aluminum, steel rockers use less mass at the rocker tip, so therefore require no more force to move than aluminum rockers. The aluminum rocker on the left is a Crane Gold Race while the steel rocker on the right is a COMP Cams Hi-Tech

A gold dredge is a placer mining machine that extracts gold from sand, gravel, and dirt using water and mechanical methods.. The original gold dredges were large, multi-story machines built in the first half of the 1900s. Small suction machines are currently marketed as "gold dredges" to individuals seeking gold: just offshore from the beach of Nome, Alaska, for instance.

Apr 13, 2013· What I saw was the fine gold was acting as a lag deposit. The lights were gently skimmed off by the rocking action and the thin film of water. Now you know why I'm a fan of thin-film recovery systems. In the case of the above rocker, there can be no thin-film action. The fine gold and everything else is trapped in the expanded metal.
Nineteenth century gold miners used wooden sluices that were at least 12 feet long, but modern gold prospectors primarily use sluice boxes made of plastic or metal which are typically 24, 36 or 48 inches long and 6 to 10 inches wide. The idea is to position a sluice box in a running stream so that the water does the work-- separating the dirt
