Placer mining, ancient method of using water to excavate, transport, concentrate, and recover heavy minerals from alluvial or placer deposits. Examples of deposits mined by means of this technique are the goldbearing sands and gravel that settle out from rapidly moving streams and rivers at points where the current slows down.

· The discussed basic features of geology of gold placers in Transbaikalia include: long extent, occurrence of a gold pay streak nearby gutter, small thickness of a gold pay streak and deep occurrence sometimes, majority of fine flattened gold particles. It is suggested to enhance development of such placers using new engineering solutions.

ers mining placers or cobaltrich ferromanganese crusts, for instance, technology must be able to cope with the effects of the ocean environment—storms, waves, currents, tides, and winds. Other problems are specific to a deposit or location (e. g., the presence of ice) and hence require technology specially designed or adapted for that location.
Over 1400 towns or camps were set up along hillsides along mountain streams. Miners worked the streams with long toms searching for gold in the surface gravel, but this supply was depleted rapidly, and placer mining went into a steep decline on the western slope of the Sierra Nevada from 1854 onwards.

the domestic gold placer mining industry and is one of a series of profiles of major mining sectors. Additional profiles describe lode gold mining, lead/zinc mining, copper mining, iron mining, and several industrial mineral sectors, as presented in the current literature. EPA prepared these profiles to enhance and update its understanding of the mining industry and to support mining program
Underground mining took place in both hardrock and placer deposits and used excavation, support, hoisting, ventilation, and drainage technologies. Early miners dug shallow shafts to reach the ore body, which they then followed to create "rathole" or unplanned underground workings. Engineerdesigned or planned underground workings became more typical by the end of the nineteenth century.
Taking gold out of a sluice box, western North America, 1900s Using a sluice box to extract gold from placer deposits has long been a very common practice in prospecting and smallscale mining. A sluice box is essentially a man made channel with riffles set in the bottom. The riffles are designed to create dead zones in the current to allow gold to drop out of suspension. The box is placed in
Mining Mining Placer mining: Placers are unconsolidated deposits of detrital material containing valuable minerals. The natural processes by which they form range from chemical weathering to stream, marine, and wind action. Typical minerals recovered in placers are gold, tin, platinum, diamonds, titaniferous and ferrous iron sands, gemstones (rubies, emeralds, and sapphires), and abrasives

· Unlike hardrock mining, which extracts veins of precious minerals from solid rock, placer mining is the practice of separating heavily eroded minerals like gold from sand or gravel. The word placer is thought to have come from Catalan and Spanish, meaning a shoal or sand bar.
Here is practical, timely information on Placer Mining Methods and equipment used in placer gold recovery. Included is detailed information on equipment, practices, recovery factors, efficiency, design, and, where available, costs. Selected gold recovery operations are described in detail. In addition, the reported efficiency and reliability of various types of equipment used today is
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
Table of ContentsPlacer MiningGeneral Geology of PlacerGold DepositsCharacteristics of Placer Gold Prospecting for placer gold, except perhaps in the case of buried placers, is the simplest form of prospecting. Gold, platinum, and tin are the principal metallic minerals won from placers, but gold (alloyed with varying percentages of silver) is the only metal that has been recovered in
Alluvial gold mining The gold dust particles are mostly granular or scalelike, and the particle size is usually to 2 mm, but there are also gold particles weighing a few kilograms and more powdery to the naked eye. The fineness of the placer gold is usually 850900
Gold mining was at first only carried on in the beds of rivers and ravines or along their banks, where coarse gold was found, with comparatively little labor or expense in the extraction of it. However, as the easy gravels were depleted, the miners moved from one technology to the next in their quest to obtain placer gold. Placer mines are divided into many classifications. The first and most
