Plan, Design and Build a Homemade Gold Rocker Box. Take the time to consider your own plans, review the rocker photos and design drawings on this page and build what is best for you.
One design I idea that I did have, which you might consider, is that if it is properly built with a removable hopper, the rocker base could also be used as a simple sluice box in locations where enough water flow is present to run a sluice so long as the hopper and frame as well as the feet are removed first. This type of dual purpose sluice or rocker would work well with a design made from a sheet aluminum body - the turn of a few wing nuts and with a few bolts one could easily go from a sluice to a rocker or vise versa in just a few minutes - there is a lot of similarity between the two types of equipment.
If you don’t already own a welder, this project might be just the excuse you needed to buy one! The Gold Prospectors Forum. Gold Watch Project. Gold Watch Project.

Modern Day Placer Mining in Yukon - Energy, Mines and Resources - Government of Yukon. Articles:View the articles below, or download a copy of the Modern Day Placer Mining in the Yukon publication The Makings of a Placer MineBy Elaine Schiman When Tara Christie's family first began placer mining in the Yukon in the mid-eighties, she was a child, just eight years old.
She has fond memories of living on their claim at Scroggy Creek near Dawson City during the Yukon summers, and wandering in the bush with her dad, exploring and testing for gold. Fast forward twenty-odd years to the present day and at 30, Tara is now a full participant in the family's placer operations near Dawson City, and serves as the Executive Director of the Klondike Placer Miners' Association. Although still a young woman, Tara, along with other Yukon placer miners, has seen tremendous changes in the way their industry operates in the Yukon. "Placer mining has been a mainstay of the Yukon economy for more than 100 years," says Mike McDougall, the President of the Klondike Placer Miners' Association. Yukon Gold (TV series) Yukon Gold is a Canadian reality television series produced by Paperny Entertainment that airs on History Television.
The series follows four mining crews as they search for gold over the four month Yukon mining season. In the first season, miners Ken Foy, Al McGregor, Bernie Kreft, and Karl Knutson each led one of the crews.[1] Cam Johnson's group replaced Kreft's crew in the second season. The series was acquired in the United States by National Geographic Channel and aired starting in 2013.[2]

TYPE IAO/BR100 -24 Kg/day Gold Refining System -12Kg/Cycle. Introduction to Assaying The assaying process is a necessary step to determine the quantity of precious metals present in an alloy. Cupellation is one operation of the assay process in which a sample of gold, wrapped in lead foil, is melted in a special crucible known as a cupel: this cupel has the capacity of absorbing the non-precious metals contained in the gold alloy. The weight of the gold alloy sample is usually about 250/1000. Although this is the most ancient method to determine the purity of an alloy, assaying by means of cupellation gives greater precision than more modern methods (fluorescent or x-ray spectrophotometry) and is considerably less expensive.

ANALYSE Marché de l'or: du rififi chez les raffineurs suisses En abritant à elle seule la moitié des firmes européennes de raffinage d'or reconnues pour leur standard de qualité par le marché de Londres, la Suisse coule des jours tranquilles en restant l'un des premiers exportateurs mondiaux de lingots. Mais la belle époque des années 1960-1990 est révolue. Les anciennes filiales d'affinage nationales de UBS, SBS et Crédit suisse ont depuis été rachetées, en partie par des capitaux anglo-américains, allemands ou du Moyen-Orient.
Elles sont aussi soumises à une plus rude concurrence: le marché international du métal jaune s'est diversifié et la vente physique se déplacée de Zurich vers Dubaï, pour alimenter l'Inde ou la Chine.
