Materials
Building a sluice requires some basic materials. You need a sturdy wooden frame, a metal or plastic screen for the sluice, and a few rocks. It is best to choose a fast moving water stream. Then, find the place where the current is strong. Build the sluice as close to the water's flow as possible, with the input end higher than the discharge end. Brace the sluice in the current with rocks.
The bottom section of your sluice will be the largest piece of your sluice, so start by cutting the boards that will make up the sluice box. Next, measure and mark the riffles. If you're using plywood, cut it to a size that will cover the entire riffle width. Once that's done, you're ready to build the sides.
The riffles are what will catch the gold. You'll need some materials beneath the riffles, such as miner's moss. Or, you can use home carpeting material. In the early days, riffles were the only materials used. These early sluice boxes did capture a large amount of gold, but did not have access to matting materials. You can purchase pre-made matting if you don't have it yet.
Another material you'll need is gravel. Gravel acts as a rock brace and provides stability to the sluice box. If you're planning to use a pump, make sure it's powered. Your pump will have to be able to supply water at the correct pressure. You'll also need a valve to control the flow of water. Afterward, attach the spray bar to the box using bolts and steel strappings.
Methods
Depending on the circumstances, a sluice can be built from wood or metal. The sluice tapers to a narrow width that is midway up the sides. It may be necessary to weigh down the sluice in the water, or the strong current can carry it downstream. If the water flow is too fast, placing large rocks on the sides of the sluice will hold it down. The sluice should be designed so that water flowing over it is fast enough to catch material.
Sluice boxes come in many configurations and can be purchased from manufacturers. However, if you want to build one for your own use, you can make your own. It is not difficult to build one yourself. Over time, sluices have become more sophisticated and are available in many variations, including long toms and dip boxes. Listed below are some of the most popular types. To build your own, follow these steps.
First, you should determine the amount of water needed to process a ton of rock. One ton of water is equivalent to approximately 2,000 pounds of rock, so a sluice with a higher slope would be more effective. Besides, larger rocks require a higher volume of water, which leads to more gold losses. Another important consideration is how many collectors you want to use. You can use plastic, indoor-outdoor carpet, or cocoa matting for the sluice bed.
Pump
Pumping a sluice is an essential part of gold prospecting. You'll want to use a pump if you want to recirculate the water and avoid having to scoop the gold concentrate out. There are two types of pump available, the traditional sluice and the recirculating pump. Both will work to recirculate water and keep the gold concentrate in the bucket.
Design
A sluice gate is one of the main components of an irrigation channel. Various calculations must be performed to determine the best gate design. These calculations include the field topographic survey, soil and hydrological investigations, and design of the sluice gate and spillway. Depending on the size of the water channel, a sluice gate can be made of several parts. Listed below are the parts of a sluice gate.
Sluice boxes are commonly used for gold and black sands recovery. They may be small enough for home-use, or they may be large enough for commercial use. The design of a sluice box should take into account the volume and speed of the water to maximize the recovery of fine gold. This will ensure a higher level of gold recovery. For smaller-scale operations, however, high flowrates will produce high throughput rates and increased fine gold losses.
A basic hand-fed sluice box doesn't have to be very long. It can be anywhere from three to five feet in length. It can also be as short as a foot or two, with a height of six to twelve inches. It should be located in a shallow section of the stream. The depth of the sluice doesn't need to be very deep, just enough to capture the water and retain gravel in the bottom.
Using miner's moss
Using miner's moss in your sluice box is an excellent way to catch gold and heavy black sands. Because of its endless loops of rubber filaments, it can easily load with fine gold and heavy heavies and clean them up by vigorous stretching in water. You can use miner's moss to build a new sluice or simply refresh an old one. If you don't have any of these materials, you can use a floor slip-resistant waterproof PVC CARPET in your home or office.
Miner's moss is also available at industrial suppliers and hardware stores. They are inexpensive substitutes for miner's moss. You can also use plastic or rubber mats for the sluice bottom. Just be sure to cut the backing of the synthetic mat before using it. It's important to use a thick mat that prevents the moss from moving around during the gold mining process.
To build a sluice, you should start with a ribbed mat that stretches from the top of the flare to the bottom of the mat. Then, lay a layer of miner's moss over the mat and make it slightly shorter than the mat. Once the mat is set, you can now place the metal mesh on top of it. The metal mesh should be the same length as the miner's moss. These two layers will form the riffles of your sluice.
Water flow through sluice box
The first step to achieving a good water flow through a sluice box is to level the surface. A level surface means that the sluice box is level sideways. If possible, angle the box 5-7 degrees lengthwise to improve the flow. The next step is to construct the sluice box itself. Here are some tips for making your box level. In addition, place rocks to prevent the water from running through.
The height of the water flow through a sluice box will vary depending on the amount of material you're sifting through. Ideally, the water should flow about one inch lower than the far upper portion of the sluice box. If the water level is higher than this, processing will be less effective. In order to stabilize your sluice box, add a large rock.
You'll need a sluice box that is large enough to handle a large amount of water. To achieve a fast water flow, a medium-sized sluice box will do the trick. If you're planning to use your sluice box for mining purposes, you should choose a medium-sized one with a downward slope. A short water-elevator can also be used to increase the velocity of the water flowing through the box.
