How Gravity Separation Works to Recover Metals and Minerals

Gravity concentrators use the same principles of gravity separation at higher velocities. While conventional gravity separation happens at one G force, the Falcon SB uses up to 200Gs to concentrate microscopic particles as small as 20 microns. The same principles apply, just at a smaller scale. Dense particles will settle first, and light ones

Gravity

Gravity (from Latin gravitas 'weight'), or gravitation, is a natural phenomenon by which all things with mass or energyincluding planets, stars, galaxies, and even light are attracted to (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the tides of the oceans. The gravitational attraction of the original gaseous
