Portabel Alluvial Placer Gold Washing Plant Trommel Sluice Box

Short Description:

Gold Trommel washing plant  is easy to move and install,  and its capacity can reach 300 ton/hour. It is mainly used to recover the alluvial or placer gold particles in the black sand.It only consumes water and electric power without chemical involved, so there is no pollution for the surrounding environment.

It can be also redesigned by the specific requirement of the customer, other machines and equipment can be installed easily to the plant in order to increase the recovery rate and to achieve a higher efficiency. Such as shaking table, sluice box and etc.


Product Detail

Product Tags

The gold wash plant is a complete set plant which including the feeding hopper, rotary trommel screen or vibrating screen (depending on the mud amount in the sand),water pump and water spray system,gold centrifugal concentrator,vibrating sluice box and fixed sluice box, and the mercury amalgamator barrel and induction gold melting furnace.

Based on your technical requirements, we can design and build a plant to target your minerals. If you want assistance with getting your plant setup on site and operational, we provide those services based on decades of our successful mining.

Advantages Of Gold Trommel Equipment

1.It is a highly economically viable option adequately suitable for small to large volume processing of materials.

2.The screen features various filters for different heavy duty drums that ensure complete separation of fine materials.

3.The design has a end user flexibility that allows for screen replacements depending on mesh sizes

4.Multiple layers of screen to enhance the sifting process.

5.It features changeable screen plates so that worn out parts can be replaced.

6. Trommel screen has high efficiency and a big capacity for different volumes of materials

7.The screen is uniquely designed to facilitate higher capacities, provide longer screen life and avoid material clogging.

Working Process Of The Placer Gold Washing Plant

After finishing installtion of the whole plant. Usually use excavator or payloader to feed the river sand into the hopper, then the sand go to the trommel screen. When the rotary trommel screen is rotating, big size more than 8mm sand will be screened out, small sizes less than 8mm will go to the gold centrifugal concentrator or vibrating gold sluice ( usually we recommend concentrator, as it can achieve high recovery rate for different gold particle sizes from 40 mesh to 200 mesh). Following the concentrator is gold sluice with gold blanket, which is used to recover the remaining gold in the concentrator.

Gold centrifugal concentrator is to use the gravity centrifugal force to collect the gold concentrate in the river sand or soil, it is suitable to collect the gold mesh size from 200 mesh to 40 mesh, the recovery rate for free gold particles can reach high to 90%, it is a perfect partner working with the gold trommel screen plant.

Gold Sluice With Blanket

After collect the gold concentrate fromo the centrifugal concentrator and gold sluice blanket, the most common way is then put it on the shaking table to further improve the gold grade.

The gold ore concentrate collected from the shaking table will be put in the small ball mill, or we call itmercury amalgamation barrel. Then it can mix with the mercury and form the gold and mercury mixture.

Electric Gold Melting Furnace

After get the mixture of gold and mercury, you can put it in the elctric gold melting furnace and heat it, then you can get the pure gold bar.

Gold mercury distiller separator

The mercury distiller separator is the device of separating mercury and gold. Mine Gold Mercury Distiller is widely used in small gold mining plant for evaporation of the Hg from the Hg+ gold mixture, and refining the pure gold.Due to mercury gasification temperature is below the melting point and boiling point of gold. We commonly used the method of distillation to separate the gold from amalgam mercury.
