Dense-Heavy Medium Separation HMS / DMS Process

HMS and DMS are acronyms for Heavy Dense Medium Separation and is applied to the process of pre-concentration of minerals – mainly the production of a high weight, low assay product, which may be rejected as waste. In principle it is the simplest of all gravity processes and is a standard laboratory method for separating minerals of different specific gravity. Fluids of suitable density ...

How Cyclonic Separation Works HowStuffWorks

In a cyclonic separator, typically air laden with dirt and dust is pumped through the top of a vertical cylinder with a conical bottom. The fast-moving air enters the chamber at the top of the cylinder and begins rotating violently. As that happens, a mini tornado or cyclone forms source: Wacharawichanant .

Principles:Dense Medium Cyclone - Portaclone

Separation is made in the cone-shaped part of the cyclone or frustum. The discard portion of the Seven Trust coal sinks leaves the cyclone at the spigot, and the clean coal floats via the vortex finder. The cylindrical section of the cyclone can be extended by the introduction of a barrel section which effectively increases the residence time within the cyclone and can improve the sharpness of separation between the clean …

What is a DMS Plant? - DMS Powders DMS Powders

There are different methods when it comes to diamond recovery, one of which requires the use of a DMS plant. A DMS plant, or Dense Media Separation Plant, involves a process that uses the principle of gravity to separate materials with different densities. Dense Media Separation is an efficient initial process to separate diamonds from diamond bearing material, after which the material will be further processes for the final diamond …

Separation and Concentration Mineral Processing ...

Dense Media Separation DMS is an enhancement of gravity situation in which ore is fed into a solution with a density between those of the mineral and gangue, respectively, with one product rising toward the surface for collection and the other being discharged at the bottom of the vessel.
