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

AMIT 145: Lesson 3 Dense Medium Separation Mining Mill

For example, a 400 tph feed to a dense medium process equates to a volumetric flow rate of 1000 gallons/min or 3.785 m 3 /min. At a 4:1 medium-to-coal ratio, the volume of medium is 15.14 m 3 /min. To achieve a Ï m = 1.50 RD, the required amount of magnetite in the medium is 704 kg per m 3 of medium or 10664 kg/min = 10.7 tonnes/min. Magnetite

Development of the density distribution model in a gas

The air dense medium fluidized bed dry coal separator uses gas-solid phases as the dense medium for coal separation, where the solid phase is magnetite powder. When fluidized, the state of the gas-solid phases of the bed performs like a fluid, and the heavy and light materials are separated by their densities. There are several factors
