Industrially, the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles. An aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and suspensions in air are used in waterdeficient areas, like areas of China, where sand is used to separate coal from the gangue minerals.

A Dual Loop Control System For Dense Medium Coal . dense medium coal washing process. The controller is designed to improve the separation efficiency and energy efficiency of the dense medium cyclone coal beneficiation process simultaneously making use of a model predictive control (MPC) method and a pumpedstorage system.

At this prep plant, all feed coal (ROM) is crushed to 2" before entering the plant circuits. The 2" x 10 mesh coal is screened and goes to the primary dense medium cyclone circuit. The 2" x 10 mesh coking coal is recovered from the refuse here. The middlings (10 mesh x 60 mesh) are processed in the Secondary Dense Medium Cyclone Circuit to ...

The medium density at which the separation between more dense and less dense material occurs is called the cut point density. Invariably, there often is a percentage of the feed coal distribution which gets trapped in an envelope of zero velocity inside the cyclone .
