Sluicing and the sluice box

Sluicing is much quicker, nevertheless the only problem is that it causes the little flakes of gold to be lost and a lot of water is necessary if you are going to be doing it this way. Rockers are not as quick as sluicing but they are still quicker then panning and the advantage you have with them is that you do not waste as much water as you would with a sluice. You are still going to need to employ your pan in order to search and once you have found a good spot, you should set up the rocker or the sluice and start throwing dirt.

A sluice is in general defined as an artificial canal, which causes flow-controlled amounts of water. In gold placering, the sluice consists of sluice boxes that collect the gold by a diversity of configurations of riffles, corrugations, mats, expanded metal, etc that then catch the heavier specks and particles while at the same time allowing the waste to go through.

A necessary element of any sluicing operation is the water supply it has to have, and if you are working in a place where there is not a great amount of water, pumps, pipelines, or even dams, it is possible special head gates may be necessary.

Small scale sluicing by hand methods has been called pretty suitably shoveling into boxes. On the other hand, in ground sluicing, usually a more proficient operation, most of the digging is accomplished by the action of water flowing freely over the materials that are going to be mined. In whatever case, the materials go through a sluice, where gold is attained behind riffles.

A variant of the sluicing technique, where water is accumulated and let out adjoining to or diagonally from the materials sporadically, is known as booming.

The sluice box in its easiest structure may be a 12-foot long board of 1 by 2 inch pine lumber, and the sides that are around 10 to 12 inches in height are nailed with braces held at a number of places across the top. Bigger sluices can be arranged with strips of wood to cover up joint in between boards where the gold may perhaps fall out, and with support built around the outer part of the box for improved firmness.

A sluice is a very uncomplicated thing to use. All you have to do is set up the head a little higher than the tail. You can practice by setting the angle at ten degrees to start off with and observe if that works if not you should carry on until you get it right. You will then need to dig a channel so the tailing that comes out of the bottom do not build up and cause it to obstruct the flow of the water. The head needs to be set close to the stream and so that you are able to redirect some of the water in the stream into the sluice, and then you will need to shovel dirt in the head end through the growler.

The water will take care of rinsing the dirt away at the same time as the gold gets stuck in between the riffles. You will need to keep on shoveling and sluicing until the sluice is full of gold or until you become tired of it. Once the sluice is full or you are tired, you can stop the water and the get gold out and this can be done by either picking it out, amalgamating it with mercury or by scraping the sand out from behind the riffles and then using the pan to pan it.

Within the sluice box, a variety of kinds of riffles might be used, depending on the handiness of the material and whatever you prefer using. The riffles, which go on the bottom, are commonly set diagonally in the box, but they can also be proficient when situated lengthwise. They may be of wood, or of strap or angle iron, or an arrangement or combination of both of them. Straight, round poles or a pattern of square blocks or stones can be used as riffles as well. Rubber or plastic strips can also be used.
