Application of lean Six Sigma to improve the dense medium separation performance at a diamond processing plant in Namibia

open access: yesCogent Engineering, 2023
Lean Six Sigma (LSS) is a rigorous, data-driven, and results-oriented process improvement philosophy. To date, there is no evidence of a study of the application of LSS in a diamond plant.

DENSE MEDIUM CYCLONE OPTIMIZATON [PDF]

open access: yes, 2005
Dense medium cyclones (DMCs) are known to be efficient, high-tonnage devices suitable for upgrading particles in the 50 to 0.5 mm size range. This versatile separator, which uses centrifugal forces to enhance the separation of fine particles that cannot be upgraded in static dense medium separators, can be found in most modern coal plants and in a ...

The beneficiation of tailing of coal preparation plant by heavy-medium cyclone

open access: yesInternational Journal of Coal Science & Technology, 2018
Dense-medium cyclones have been used for beneficiation of fine particles of coal. In this study, the usability of cyclones in the beneficiation of tailings of a coal preparation plant was investigated.

Medium Density Control for Coal Washing Dense Medium Cyclone Circuits [PDF]

open access: yesIEEE Transactions on Control Systems Technology, 2015
The dense medium cyclone (DMC) process used in coal beneficiation plants is studied from a control system perspective. Employing the dynamic model of the DMC process derived from mass flow balance, a model-based control strategy is proposed. The controller adjusts the density of medium used to enhance separation in the DMC process according to ...
