The shaking table is a vital piece of equipment in the field of mineral processing, particularly for the separation of fine particles based on their density. It is widely used for recovering precious metals such as gold, silver, and tin from ores. In this article, we will explore what a shaking table is, how it works, and its benefits in ore processing.

A shaking table, also known as a concentrator table, is a gravity separation device that utilizes the differences in density and particle size to separate valuable minerals from waste material. The table has a flat surface that is inclined and shaken, allowing lighter materials to be washed away while heavier particles settle.

The operation of a shaking table involves several key components and processes:

1. Feed Material

The process begins with the feed material, which consists of crushed ore mixed with water. The mixture is introduced onto the surface of the shaking table.

2. Inclined Surface

The surface of the shaking table is inclined at a slight angle, typically between 3 to 5 degrees. This slope allows for the effective separation of particles based on their density.

3. Shaking Motion

The table is equipped with a mechanism that creates a shaking motion. This motion can be adjusted in terms of frequency and amplitude. The shaking causes the material on the table to move back and forth, enabling the separation process.

4. Water Flow

Water is continuously added to the table, creating a flow that helps move lighter particles away from heavier ones. The water flow must be carefully controlled to ensure optimal separation.

5. Particle Separation

As the table shakes and water flows over it, lighter particles are carried away with the water, while heavier particles sink and settle on the table surface. The heavier minerals, like gold, remain on the table, while waste material is washed off.

6. Collection

The separated materials are then collected from the table. The valuable minerals can be further processed to extract the desired metals.

details about shaking tables

Shaking tables offer several advantages in ore processing:

1. High Recovery Rates

Shaking tables can achieve excellent recovery rates, particularly for fine particles. They are efficient in separating even small amounts of valuable minerals from the ore.

2. Versatility

Shaking tables can be used for various minerals, including gold, silver, tin, and tungsten. This versatility makes them suitable for different mining operations.

3. Low Operating Costs

Once set up, shaking tables have relatively low operational costs compared to other separation methods. They require minimal maintenance and can be operated continuously.

4. Environmentally Friendly

Shaking tables do not require toxic chemicals for the separation process, making them a more environmentally friendly option compared to some other methods, such as cyanidation.
