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

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.
