A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006. 15.4.2 Stratification and Hindered Settling. Stratification due to the nearly horizontal action of the table deck and the flow of water is not the only mechanism at work on the table. There is some suggestion that hindered settling may also assist in the separation in some ...

stratification geology Britannica

Stratification in sedimentary rocks may result from changes in texture or composition during deposition; it also may result from pauses in deposition that allow the older deposits to undergo changes before additional sediments cover them. A sequence of strata, therefore, may appear as alternations of coarse and fine particles, as a series of colour changes resulting from differences in mineral ...

Minerals Free Full-Text Jigging: A Review of ...

For centuries, jigging has been a workhorse of the mineral processing industry. Recently, it has also found its way into the recycling industry, and the increasing concerns related to water usage has led to a renewed interest in dry jigging. However, the current scenario of increasing ore complexity and the advent of smart sensor technologies, such as sensor-based sorting (SBS), has ...
