Shaking table gravity separation method is a mineral separation method based on gravity difference. Its working principle is to use the tilting and shaking motion on the surface of the shaking table to make the ore move in different directions under the action of water flow, thereby achieving mineral separation(Comparative Analysis of Gravity Separation Techniques for Ores – Xinhai, n.d.).
The shaking table continuously vibrates, so that the heavier minerals settle below the bed surface, while the lighter minerals stay above the bed surface or flow to the discharge port. Shaking tables are rectangular-shaped tables with ribbed decks with a water film flowing on them. Water flowing along the long axis of the table slurries the fed sample. Low-density particles are transported in the fast-moving film, causing fine, high-density particles to fall into the beds behind rifles. With the rapid backward movement of the table, the particles gain a forward movement thanks to momentum, so each structure is separated from the other. Separation performance in shaking tables is directly related to particle size distribution(4 Common Gravity Separation Methods – Xinhai, n.d.).
What’s the secret to efficiently concentrating minerals based on subtle differences in density and size, even from fine feeds? The answer lies in the dynamic action of a shaking table! What’s a seemingly simple technology in your industry that achieves surprisingly complex separations? Let’s discuss!
