Diamonds are created deep within the Earth, in an area around 100 miles under the Earth's surface known as the upper mantle. The carbon that exists there is under a tremendous amount of pressure from all of the material above it and the temperatures are very hot. The carbon atoms bond together to form crystals that …

 — Dense Medium Separation (DMS) stands as a cornerstone in the realm of mineral processing and ore beneficiation. At its core, DMS leverages the inherent density differences between valuable minerals and gangue materials to achieve highly efficient separation. This ingenious process relies on a dense medium—a suspension of finely …

 — For alluvial mines: Through washing, screening, grading to remove mud, separating large gravel and fine mud tailings, and clean sand jigging separation, coarse concentrate can be obtained. In the …

Since most diamonds are small, removing larger gravel with the quarter-inch screen helps process the dirt more efficiently. Two or three people can easily share one screen when wet sifting. While one person searches their wet sifted gravel for a diamond, a second person can use the screen to sift more dirt.
