For instance, in the processing of titanium-bearing minerals, magnetic separation is often used as a pre-concentration step, followed by electrostatic separation for final purification. Factors Affecting Electrostatic Separation. Particle size: Electrostatic separation is most effective for particles in the range of 0.1 to 2 mm.

separation and eventually sorting different particles [2]. When water is removed, and air plays the role of separation medium, the separation method is defined as dry, pneumatic, or air gravity separation [3]. In general, dry gravity separation has the attraction of decreasing capital and operating costs compared to the wet mode.

While the ultrasonic separation may work well on a small unit with dry sand, I am wondering if it is practical to scale this idea up to a unit with a hopper of 20-40 litres capacity. Also, as it is not practical, at the claim site, to dry sand in large quantities, I wonder how feeding damp sand into such a machine would effect its operation.

And while the gold content itself is usually just as valuable, extracting it could be more challenging. To retrieve fine gold you need a recovery tool with fine riffles or some type of fine matting. A normal gold pan will do if handled in a gentle manner, but a finishing pan with small riffles will make retrieving the gold much easier.
