Rocker boxes were also popular during the Klondike gold rush for working the hillside placers that were far above the creeks. The ''rocker'' is a box with a hopper about 3 to 4 ft. long and 1 to 2 ft. wide, sloped like a cradle, and is mounted on semicircular pieces of wood and worked by a, handle to give it a side motion; and it is also inclined so as to carry the material down to the lower end
Gold USGS. used gold lavishly in decorating tombs and temples, and gold objects made more than 5,000 years ago have been found in Egypt. Particularly noteworthy are the gold items discovered by Howard Carter and Lord Carnarvon in 1922 in the tomb of Tutankhamun. This young pharaoh ruled Egypt in the 14th century
Gold rush era (1896~1899) During the gold rush some gold was found in the creek beds, but most was in the valley gravels near and in bedrock. The recovery had two steps: bringing the gravel containing gold to the surface and then separating the gold from the gravel using water and gravity separation, as a result access to water was important since it was necessary for the separation process
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 highsided 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.

The price of gold was controlled as a gold standard of 20 per ounce from 1792 until the 1930s during the Depression President Franklin D Roosevelt stopped the run on the banks and hording of gold in 1934 also raising for the first time the price of gold to 35 per ounce
Bronze Age gold objects are plentiful, especially in Ireland and Spain, and there are several well known possible sources. Romans used hydraulic mining methods, such as hushing and ground sluicing on a large scale to extract gold from extensive alluvial (loose sediment) deposits, such as those at Las was under the control of the state but the mines may have been leased to
The rocker box, or quot;cradle,quot; was a popular tool used by miners during the early gold rushes. They were portable devices that were able to capture much more than just a gold pan alone. Their design was relatively simple. Rather than using an active flow like a sluice, water was fed into the head of the rocker box manually using a tin can.
#0183;#32;One of the most popular pieces of equipment used during gold rush times in XIX century was a rocker box, sometimes called a cradle. Collier''s New Encyclopedia from 1921 defines this device as a mechanical contrivance used in placer mining, consisting of a box on rockers and moved by hand, used for washing out the goldbearing soil.

Jul 15, Isaac Humphrey may or may not have introduced the rocker box to the California gold fields around 1848 during the Gold Rush. Popular Use in the Early Goldfields The rocker box replaced panning for many prospectors searching for placer gold deposits, particularly once a deposit was found and the miner wanted to process more gravel..
A mining tool called a rocker (also known as a cradle) was widely used during the Gold Rush to separate lighter gravels from heavier gold bearing sands, at a Gold Rush reenactment in Coloma. Buy this stock photo and explore similar images at Adobe Stock
A rocker, also known as a cradle, separated gold from dirt. This tool consisted of a box for shaking dirt and water back and forth so miners could find gold fragments. A miner would load the rocker with water and soil. Another would rock the box, bucket load after bucket load, to search for signs of precious metal.
This gold cradle was the first to be used in Australia. It was made by William Tom Jr following directions from Edward Hargraves and was based on similar cradles (also called rockers) used to wash for gold in California. The cradle was a box with two metal sieves. Earth and water were shovelled on t...
Rocker boxes were generally very inefficient and it took a very long time to process any appreciable amount of material. They are almost never used today because they are generally much better equipment to use, but during the early gold rushes throughout the they were very common.
Who Used The Rocker During Gold Eyewitness to the Discovery of Gold at Sutter''s Mill 1848 An eyewitness to the discovery of gold at Sutter''s mill in 1848 describes how the discovery was made, and what happened during the first weeks following the finding
A long tom is a method used for small scale mining that is far more efficient then either the gold pan or the rocker as it is less work then these other methods. The long tom was originally used by the fortyniners in late 1848 just when the California gold rush was just getting underway.
Panning gold was slow work and very early in 1848 Isaac Humphrey, a miner whod been at the gold finds in the mountains of Georgia in the 1830s, introduced a new device that sped things up a great deal. Called a rocker or a cradle, it resembled a babys bed. At the upper end was a hopper with moderately high sides and covered with a sheet metal or rawhide sieve with holes a halfinch in
The rocker box was especially useful in localities where limited water flow prevented the use of sluices and other techniques. In addition to its use in smallscale placer mining operations, the rocker box found fairly extensive application in sampling gold prospects. The rocker
