Welcome to GWP, where we make high-quality, affordable gold wash plants for sale. Our product lineup is designed to efficiently handle anywhere from 30 to 300 tons of material per hour. Each wash plant has three proportionately sized sluice boxes designed to optimize gold recovery in all conditions.
Each machine is a complete portable plant; there is no need for additional screens or sluice boxes! At the top is an extreme duty grizzly bar section that will take up to 24-inch rocks (91 cm). Classification begins when the material is placed on the grizzly bars, and high-pressure water separates the sub-1 (25.4 mm) material from the large rocks. Next, the screen deck further classifies the material, and sub-.25 (6.35 mm) material drops into the sluice boxes, remaining sub-1 material passes through the nugget trap into the final riffle set for capture, and larger rocks get discarded.The sluicing system has three boxes that are independently adjustable, and with anywhere from 20 feet of sluice box on our 50-ton units to 40 feet of wider boxes on the 200-ton units, gold recovery is excellent. It often exceeds 95%, even with fine gold down to 200 mesh! Whats the key to such remarkable recovery? Science. This portable gold mining equipment was based on the performance data found in a landmark technical report on sluice boxes and riffle systems. Watch the video of our M50 wash plant.
Our wash plants for sale are always mercury-free, and they require no additional recovery equipment. Setting up your wash plant is fast and easy--it usually takes less than 2 hours. When you need to move the mining site, you can drag the excavator and enjoy the ease of a highly portable wash plant.
Our machines range from 30 to 300 tons per hour while maintaining a long life and less downtime. Reliability is essential to save time and increase profits. We ship worldwide so that you can pay less money and recover more gold than other machines.
~ Reinforced 3/16 steel hopper base (most built with 1/8 steel), side loading (either side) with a hopper length of 10(120) and a width of 52(62), ideal for backhoe, front-end loader or skidsteer loading, which feeds down to 32 x 25 screen (3/8 classification) to sluices (reinforced below screen for stability).
~ Height of the hopper for transport is 78 (66) tall at about a 3% grade, but two front jack stabilizers increases pitch up to 18% grade, with center jack with two locking pin guides with multiple setting heights.
~ 4 heavy duty springs (rated at 2k lbs each) between the hopper and the frame to allow for hopper to vibrate more freely. Hopper weight is approximately 600 700 lbs, so even with a full yard of material (around 2500 lbs), the springs are more than adequate.
~ Reinforced with galvanized steel pipe water lines over hopper sides and screen deck (to protect lines when feeding hopper). Screen deck water lines were made adjustable, to adjust pitch of spray through the wash chute.
~ Flared slick plate, which is to send pay material from the collection to the sluices, this is 17 (to match to sluice), so set up to run into 18 wide sluices, which seem to work ideal with 2 to 3 water pump.
~ 3 concrete vibratory motors (along with carriage bolts) with this unit, one (already installed) on the steel plate mounted directly to the screen deck and two new additional concrete vibrators for the hopper. As this is brand new, it is better to start running water and material first through hopper area, before determining the best position for those concrete vibrators. These can be easily ran from a small generator.
New, basic units like this sell for $12k+ (when you can find them, without shipping costs, and without as many adjustable features). Again, I am not planning to include hoses (to and from pump and to connect to wash plant), generator, sluices or trash pump in the package, but can make a bundle package for it all, for $7,000.
Selling because; In the spring of 2019, a fellow mining colleague and I, built an additional wash plant (the grey one you see being loaded) to use for taking samples and running material at one of our side operations. We found that this is an excellent unit for someone to run solo, perhaps with a backhoe or small piece of equipment. But as our other operations expanded we found little use with our larger operations and other trommels and equipment we ran. The first (grey) wash plant was a great unit, easy to maneuver into place, no hauling issues whatsoever. In the fall of 2019, we posted an ad, and the unit sold in two days. I had several of my long-term clients a bit upset that it sold so fast, so over this last winter (while I wasnt able to mine), I committed to build 4 more identical wash plants for clients. I did add in a few extra features that the grey one didnt have, and the 3 clients the other plants already went to, are pretty pleased with how their units turned out. What I will make pretty clear though, after this project taking many months to complete (longer than anticipated), I do not intend to build any more of these in the future, unless it is for my own operation, it is just not worth it to me. I have had others already inquiring, so please do not contact me to build you something, and when this unit is gone, well, that is it.
We offer consulting services and can help you decide the viability of your potential site and what mining equipment is right for you. Our gold wash plant prices are set based on the intensity of usage at these sites.
After the gold mining equipment has been transported to the site, a camp is set up for the duration of the season The mining season generally lasts from June until the ground freezes in late September or October. The camp usually accommodates from two to five people with support faculties for maintenance and storage. After the camp is established, the associated physical mining infrastructure is constructed with a bulldozer or other earth moving equipment. This Infrastructure usually consists of two or more settling ponds, associated dikes and spillways, drainage ditches to prevent erosion and collect runoff and groundwater, and working areas for the washplant, pumps, and motors. If the area to be mined is within an active stream channel, a bypass is built to route the water around the mining area. The bypass is diked to withstand ordinary floods and to keep contaminated mine water from entering the stream.
Actual mining activities usually begin after the Infrastructure has been constructed. Trees and brush are cleared, and topsoil and overburden are stripped from the area to be mined. The stripped topsoil and overburden are stockpiled (separately if possible) usually near the mine cut, and are protected from erosion and flooding. With adequate planning, these stockpiles may be placed in a manner that promotes efficient site reclamation through reduced material handling and shorter hauling distances. Topsoil may have been stripped during the preceding mining season to allow permafrost. In layers of overburden or gold-bearing gravel to thaw. If not, frozen overburden and top-soil may be ripped and stocked by bulldozer. The extent of the area to be stripped depends upon the expected rate of production. On a typical mine, one to two acres are usually stripped
Exposed gold-bearing gravels are usually mined using a bulldozer that pushes and stockpiles the gravel near the washplant. A few operations use a dragline for these tasks. The stockpiled gold-bearing gravel is then fed into the washplant by a front-end loader or large back hoe. This practice promotes equipment efficiency by allowing the bulldozer or dragline to continue mining while the loader or backhoe feeds the washplant at a steady rate. Hydraulic stripping is another method of removing overburden and is particularly efficient when the overburden thickness is considerable. This method usually requires a very large water treatment system due to the huge quantities of water used in washing away the overburden. The removed overburden is captured in settling ponds designed for that purpose.
When the mined gravel is fed into the washplant it is classified by size using various stationary or vibrating screens. Classifying provides for more efficient gold recovery, reduced water consumption. and facilitation of mine site rehabilitation, and is practiced by most mine operators. The over-size material, usually larger than two inches, slides out of the washplant into a pile where it is moved by a front-end loader or bulldozer. The undersize material and gold-bearing gravel is mixed with water and flows through the sluice box where the gold and heavy black sands are concentrated. Tailings are the gravel, sand, and other materials which accumulate at the end of the sluice box. Tailings are routinely removed by a loader or pushed away by a bulldozer.
The water that carries the gold-bearing gravel through the sluice box becomes sediment laden and turbid. This muddy process water flows from the end of the sluice box through a pile of deposited tailings and into a series of settling ponds. These ponds are designed to hold the muddy water long enough to allow the fine sediments to settle out. A limited volume of process wastewater as defined by EPA may be discharged to the adjacent stream. The physical requirements of the ponds are dependent upon the amount of water flowing through the system, the sediment characteristics of the gravels being worked, and the physical characteristics of the site. Most mines utilize a series of small settling ponds to permit flexible water management the site. Most mines utilize a series of small settling ponds to permit flexible water management. Small ponds are usually easier to build, repair, clean, replace, bypass, and rehabilitate. The use of pre-settilng ponds is encouraged.
Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.

This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate. When the mined gravel is fed into the washplant. It is classified by particle size using various stationary or vibrating screens. Classifying gravels provides for more efficient gold recovery, reduced water consumption, and facilitation of mine site rehabilitation, and is practiced by most operators. The oversize material, usually larger than two inches, slides out of the washplant into a pile where it can be moved by a front-end loader or bulldozer. The undersize material and gold-bearing gravel is mixed with water and flows through the sluicebox where the gold and heavy black sands are concentrated. Tailings are gravel, sand, and other materials accumulated at the end of the sluicebox. Tailings are routinely moved away from the sluicebox by a loader or bulldozer.
The water that carries the gold-bearing gravel through the sluicebox becomes sediment-laden and turbid. This muddy process water flows from the end of the sluicebox over a pile of fresh tailings into a series of settling ponds. These ponds are designed to hold the muddy water long enough for the fine sediments to settle. The physical design of the ponds depends upon the amount of water flowing through the system, the sediment characteristics of the gravels being worked, and the physical characteristics of the site. Most mines use a series of small settling ponds to permit more flexible water management. Small ponds are usually easier to build, repair, dean, replace, bypass, and rehabilitate than larger ponds. The use of pre-settling ponds is encouraged. A pre-settling pond is located in the tail race between the sluice and the first settling pond. Sands and other heavy settleable solids are collected here where they are easy to wash.
However, some zero-discharge systems do have occasional discharges, usually due to water seepage through pond dikes. This seepage almost always meets the settleable solids effluent standards, and in most cases, Is probably of better quality than the water discharged from typically operated settling ponds. I.e., less settleable solids and lower turbidity. Carefully designed and Implemented water management practices are required to achieve zero discharge of muddy water into adjacent streams. Water used in the sluicing process Is pumped from the nearby stream through the washplant and into the settling ponds. Water Intake from the stream Is suspended when the ponds contain adequate water to support continued sluicing operations by recycling pond water to the washplant. In some cases, groundwater seepage Into the settling ponds may be sufficient to eliminate the need for adding stream water to the system. The practice of zero discharge and the recycling of mine water contributes to compliance with federal effluent limitations and State water quality standards.
Placer mining involves equipment ranging from a simple gold pan all the way up to trucks, excavators, and a gold wash plant.This type of gold prospecting usually involves less investment and will consistently yield small amounts of gold, with occasional bonanzas for those who are persistent. If you can learn to reliably return from every trip with decent concentrates, so that over time you fill a five-gallon bucket, and then maybe even a fifty-five-gallon drum, with black sands, magnetite, ilmenite, rare earth elements (REEs), and gold, you will be rewarded in the long run.
Either way, your long-term goals are your own.Very few prospectors are simply in it for the money, looking at this as a way to become a millionaire overnight. Some of us just like to get out of town, camp in the mountains, and enjoy the spirit of the outdoors. Some people like to work up a little sweat and appetite, improve their health, and learn a little. Some of us like to solve problems and run machinery, and enjoy the challenge of keeping a pump going or making sure the sluice is running right. Still others like the wildlife, the scenery, and the historical importance of the Wild West, and bring back their riches as photos and videos. In each case, if you toss in a little gold fever as motivation and stay scientific about your sampling and exploration, you will prosper far and above the value of your recovered material.
Still, a nice payday is always a treat. One sure way to reach that goal is to keep trying. Keep practicing, keep exploring, and keep getting out in the field. Another truism that seems to hold is that the farther away from civilization you get. the better your chances.
The development of a load/placer mine and the selection of the proper gravity recovery plant is more difficult than most people realize. Television shows have glamorized mining making it look like anybody can start a mine with little to no experience. What people dont realize is that mining is a structured engineering discipline taught at university. Just as you should not build your own bridge without knowledge of civil engineering, you should not think becoming a miner is a simple task. If you have no experience in the mining field you need to get educated about the process before you embark on this adventure. We have compiled a basic guide to assist in that process.
The terminology used for this type of mining is often interchanged. The term for the type of deposit under consideration is alluvial. Alluvial deposits are formed when the gold has migrated from its original deposition by weathering to a new location often inactive stream beds or in historic watercourses now overlain by sediments or glacial sediments.
In general Placer Mining is typically the recovery of gold from stream sediments through the use of dredges and sluices or other gravity means. Load mining generally involves the stripping of an overburden layer (soil) to uncover the underlying gravels that contain the gold. These deposits are often mined with mobile equipment and the ore trucked to a gravity treatment plant.
1. Permitting am I allowed to disturb the land excavating pits, leaving tailings behind, water usage, noise, air quality. In most cases you are not allowed to simply start mining even on your own land without the proper permits.
2. Resource estimation how much gold is present (grade and tonnage) and what does the deposit look like over burden depth, ore depth, gravel size. Generally, a placer resource is established by drilling or augering holes around the deposit to delineate the extent of the gold. This is often combined with field gravity recovery testing to provide an estimate of the recoverable grade.
6. Mine plan do you have a mine plan where are you going to mine first, where is the overburden going to be placed, where are the tailings going to be placed, is the plant going to be in one spot or moved during the mine life, what are the haulage distances. Is this a seasonal operation?
Mine Conditions Where is your project located? terrain, climate, infrastructure variables How large is your concession? Is a mobile or fixed plant right for this application? How many yards/hour (m/hr or tons per hour) do you want to process? How much water do you have available (GPM or m/hr)? Is there power available from the grid or do you required generation?
Plant Characteristics Are you looking for a mobile machine that you move regularly or a stationary plant that you haul your ore to? What type/size of equipment will you be feeding the plant with (front end loader, dredge pump, other)?
Feed Characteristics Ore consistency: What is the estimated maximum boulder size (in, mm)? Is there significant clay present? What is your maximum gold size (mm or um)? Is there fine gold present, what is the typical size (um)?
8. Economic Model Once you have made some initial assumptions you need to develop an economic model (even a basic one) so that you know if the project is viable before you start. No matter what type of project you should try and establish some basic economics unless this is just going to be a small hobby operation where profit does not matter. There are a lot of assumptions required to develop the model and you need to be realistic in your assessment. Add contingencies for operating costs of 10-15% and 20-30% for capital costs.
A trommel is composed of a slightly-inclined rotating metal tube (the scrubber section) with a screen at its discharge end. Lifter bars, sometimes in the form of bolted in angle iron, are attached to the interior of the scrubber section. The ore is fed into the elevated end of the trommel. Water, often under pressure, is provided to the scrubber and screen sections and the combination of water and mechanical action frees the valuable minerals from the ore. The mineral bearing ore that passes through the screen is then further concentrated in smaller devices such as sluices and jigs. The larger pieces of ore that do not pass through the screen can be carried to a waste stack by a conveyor.
Before entering hopper of trommel, raw materials are sent to the grizzly to separate large rocks, if any. After materials enter the trommel hopper, often with high pressure water pipe around the hopper to help feeding, the materials will be fully washed at the first section scrubber part, materials will be fully turned and separated inside drum. There are blades inside the drum for breaking clay, then materials enters to double drum trommel. Deya designs and produces trommel with double drums, inside drum is welded by steel bars diameter 30mm to 50mm depends on size of the trommel. This drum is to separate gravels to protect outside drum. Outside drum with screen mesh, normally 5 mm or 8 mm depends on the gold particle size potentially contained. Large rocks are separated to end of the trommel, while slurry with gold particles flow to bottom of the trommel for further process to extract gold. In brief, above steps as follows:
