The gold trommel is one of the most commonly used mining machines, and it is very popular among the miners all over the world. The gold trommel is used for mining operations of all sizes, but the main purpose is to separate gold by removing large pebbles, boulders and rocks. Explained in another way, a gold trommel is a rotating cylinder with holes that acts like a classifier, allowing only gold materials to pass through the holes, while the large materials go out of the machine.
When a material that contains gold is added into the hopper, the machine sprays high pressure water on material so that the gold particles can be extracted. Different gold trommel models use different amounts of water jets, but the main objective is to break any mud or clay that could hide the gold and prevent it from being caught in the sluice box. The hopper of the gold trommel usually has a metal grate that keeps the large rocks from entering into the machine. This device is known as a grizzly.
The procedure starts when the gold bearing material enters the rotating drum. The rotating drum is mainly constructed of screen material, which allows the smaller gravel to fall freely into the sluice box. The combination of rotating drum and high-pressure water enables the machine to break any dirt and clay inside the rotating drum. This action continues until the material is broken into small gold bearing pieces that can exit the gold trommel through the cylinder holes.
The trommel is very simple to install and use, regardless of the type. There are different types of gold trommels and they are all used for the same purpose. The only difference is the capacity of gold they can process in a specific period of time. Many operators are confused and believe that the trommel separates the gold itself. The reality is different, because the gold trommel is used to separate and classify the material for further processes.
For efficient operation, two operators are required. One to feed the material into the trommel, and another to monitor the working procedure of the gold trommel. Also, one of the operators need to ensure that the gold is being processed properly.
1) Movable, towable
2) Capacity:10~150 tph
3) Washing together with concentrators or sluices
4) Replaceable screen
Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.
Bucket Line Dredge is most effective to operate, they are indeed efficient at recovering gold.

Dredge Bucket
Trommel/Vibrating Screen
Sluice Box/Concentrator
Water Pump
Generator

Hard rock mining is usually done on a large scale, and although a few small-scale hard rock operations still exist, it's not an easy operation to start up and run profitably. The main problem for individuals or small groups interested in hard rock gold deposits is the high capital costs both for the mining equipment to dig and remove the rock as well as the equipment to crush and process hard rock ore in order to extract the gold from its solid rock enclosure. Because of this, many prospectors who look for hard rock gold seek instead to sell their finds to large companies that possess the resources to develop them.
Gravity Concentration methods are systems which use gold's high density to capture the precious metal. Gravity based equipment includes concentrators, spirals, sluices and tables. Gravity systems are often the lowest cost system, but only a certain part of the gold is usually coarse enough to be recovered with gravity systems. It is common that gold ore be processed by two methods - gravity is used to remove the coarser gold from an ore and afterward the ore is processed by cyanide to recover the fine particles of gold and silver. Gravity concentration methods are the ones most commonly used by the individual prospector.
Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold.
