Shaker Tables
Less dense, higher volume material (as in sulfides in gold ore) forms a band at the base of the ramp, reporting to the middlings tray. The lightest material stays behind and reports to the tailings tray. Other design features of the table were added to minimize turbulence, hence higher fine gold recovery to <325 mesh.

The Gold Ball Mill: A Crucial Tool in Gold Ore Processing
A gold ball mill is a type of grinding mill used in the mining industry to crush and grind gold ore into finer particles. It is an essential component of the gold extraction process, as it helps to liberate gold from the surrounding rock matrix, making it easier to extract using various methods such as cyanidation, amalgamation, or gravity separation.
