Centrifuge: Principle, Parts, Types, and Applications
The ultracentrifuge is a highly developed and sophisticated centrifuge that can separate tiny molecules that conventional centrifuges can't separate at a fast rate. Ultracentrifuge rotor speeds can range from 60,000 to 150,000 rpm. They run samples in groups or as continuous flow systems and are larger. Types of Ultracentrifuges

The myth of gravity concentration to eliminate mercury use in …
In terms of gravity separation equipment, centrifuges outperform all other equipment, as they are adequate to separate coarse and fine gold particles. The centrifugal force exerted on the particles substantially increases the difference of terminal settling velocities between the gold and the gangue minerals (Sampaio and Tavares, 2005). For ...

1.16: Methods for Separating Mixtures
One of the approaches taken to isolate the gold from the soil was called "panning". Dirt would be placed in the pan and covered with water. After thorough mixing, the pan is gently swirled to remove dissolved material while the heavier gold settles to the bottom of the pan. The gold is then separated from the mixture of soil and water.

How To Separate Gold From Dirt
One of the easiest and most inexpensive ways to separate gold from dirt is through panning. This age-old technique has been around since the Gold Rush, and makes a great outdoor hobby that can pay for itself. With a minimum of equipment, the beginner gold prospector can separate gold flakes and nuggets from the surrounding strata in a nearby stream.

If the gel plug does not move to separate the cells from the plasma (as may be evident with refrigerated tubes), the tubes should be re-centrifuged. The blood collection tubes contain a gel plug that separates the plasma from the cells when centrifuged. 3.
