The main function performed by the equipment is that of processing large volumes of gravel believed to contain gold. Since it takes tons and tons of gravel to recover even a small amount of gold, some sort of mechanism is required to separate out all the bigger gravel and worthless rocks. Once this is done, we can process only the smallest sized materials where the small gold dust and flakes will reside.
This write-up will explain how a trommel can be used to find placer gold.
This picture shows a trommel that was used inside a large bucket line dredge. 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.
First, the miner needs to dig out the gravel and separate the largest rocks. To reduce wear and tear on the trommel, most operators use a grizzly. This is the easiest way to get the big rocks out, and keep the small to medium material. Some larger wash plants contain grizzlies which may be positioned right over the trommel, allowing the separation to occur at the same time that the material is being dropped into the hopper.
After the grizzly, the contents are fed through the hopper. This is the primary feature of a trommel that makes it so efficient. A rotating drum with holes in it. This allows the material to separate as the drum rotates, and the smaller pieces fall through while the bigger rocks stay in the drum.
The hopper of most trommels also have water jets from within, which provides high pressure to break down any clay and dirt even as the drum keeps rotating while the slurry moves through the drum. This is especially important where high clays are present since it can catch and hide the gold.
All of the fine material should fall through the hopper of the trommel. It then drops into a sluice box, where the gold will be captured just as it would normally. If large rocks were fed directly into the sluice box it would blow out a lot of gold and recovery rates would be lousy.As the gold bearing material gets run through the drum, the smaller particles are able to flow through the screen material with which the drum is made, and then the material proceeds to the sluice box or even other systems of operation. The larger rocks run all the way through the trommel and are discarded.
All of the fine material should fall through the hopper of the trommel. It then drops into a sluice box, where the gold will be captured just as it would normally. If large rocks were fed directly into the sluice box it would blow out a lot of gold and recovery rates would be lousy.
Once the trommel has been used to classify the content, then the placer gold can be recovered from the sluice box in a traditional method. Only the finer material is left to run through the sluice which means that it runs very efficiently and once everything is set up properly the capture rates are quite high.
