Placer mining uses only water, no chemicals, for mineral extraction or separation. A placer gold mining machine, also known as gold trommel, is used worldwide for the majority of placer mining activities. The purpose of a gold trommel is to process the gold-carrying material by separating the bigger boulders and rocks and allowing the smaller material to go through a sluice box.
Surface Gold Extraction Using Placer Trommels Saves Env. Placer mining uses only water, no chemicals, for mineral extraction or separation. A placer gold mining machine, also known as gold trommel, is used worldwide for the majority of placer mining activities.
29-10-2018· It could process tons of gravel per minute and was large enough for a grown man to walk inside. High pressure jets of water help to break up the clays and release gold into the sluices underneath. Trommels are effective on any type of placer deposit where the gold is mixed in with loose gravels, sands, and clay.
High Recovery Rate Gold Mining Plant. 1.Product Description: KEDA Gold Trommel with Patent is easy to move and install, and its capacity can reach300 ton/hour. It only consumes water and electric power without chemical involved, so there is no pollution for the surrounding environment.

Trommels are effective on any type of placer deposit where the gold is mixed in with loose gravels, sands, and clay. It should be noted that many of the best deposits that are mined by large operations are exposed bench deposits and tertiary river gravels.Many of these areas are now “high and dry” above the current river channel, but they can still be mined efficiently if water
Small Scale Placer Mining Activities and Water Use Early placer miners and prospectors used hand-held pans to wash mineralized earth and gravel by agitation to recover placer minerals having the greatest specific gravity. Soon after, prospectors developed methods that allowed them to process pay dirt more efficiently. Sluices and high bankers
We rate these Duplex Jigs up to 56 Tons per hour, with 7/16" minus (11 mm), average water usage of up to 240 Gallon per min (900 liters per minute.) 36 inches Round Single Jig. Jig Support Structures available. Jigs and Sluices compared to: Wheels, Transverse belts, reverse spirals trommels
How much water velocity is directed over the box directly affects how much material will stay behind the riffles. When the correct amount of water force is being put through a sluice, its riffles will run about half full of material, and the material can be seen to be dancing and vibrating behind the riffles (concentrating) when the water is flowing.
As every miner knows, the biggest frustration encountered when Gold Mining is the loss of fine gold, but the Gold Machine drastically reduces those losses. Driven by the desire to catch more gold in all fraction sizes and to make mining more efficient, lower-risk, and profitable in even the leanest ground, Ray has worked for over thirty years to build the best machine possible.
Mobile gold wash plant mobile trommel screen is composed by hopper, trommel, chassis, tires, turntable, generator, water pump, gearing, control panel and gold recovery sluice. The mobile trommel screen is a optimized removable platform for gold recovery, applicable to small or medium scale of placer gold ore processing that need mobile operation.
The 911MPET400 is a 100 to 150 TPH Gold Trommel Washing Plant which features include: A fully welded tube construction main frame Variable speed Electric drive components requiring very low maintenance and zero contamination 10 Sided tube frame drum 3/8” 400F punch plate with scrubber bars Easy clean water filtration systems Emergency stop functions Baseline design of this Gold Trommel
22-07-2019· Gold is heavier than most other particles, so alternative methods typically use motion or water to separate the gold from lighter particles. Panning involves moving sediment that potentially contains gold in a curved pan with water and moving in such a way that any gold will settle at the bottom while the water and other particles will leave the pan.
