GTEK gravity feed three product dense medium cyclones are capable of not only separating coal particles but also concentrating and the heavy media at the same time to produce three qualified clean, middling, and reject products at one time.
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 .
density range, pure ferrosilicon, pure magnetite, or a blend of ferrosilicon and magnetite are used as the heavy media. The separation by density occurs in the cyclone, with denser particles reporting to the cyclone underflow and less dense particles reporting to the cyclone overflow. The density of the

Index Terms—Optimal control, dense medium cyclone, coal beneﬁciation, density control. I. INTRODUCTION Run-of-mine (ROM) coal has different impurities such as ash and sulfur contents depending on the geologic conditions and mining technique used . Clean the ROM coal to remove excessive impurities for efﬁcient and environmentally safe
However, cyclone application in magnetite grinding circuits can cause inefficient operation due to the density difference between magnetite and waste minerals (silica). Magnetite has a specific density of about 5.15, while silica has a specific density of about 2.7. In hydrocyclones, dense minerals separate at a finer cut size than lighter ...

The effect of solids loading ratio or the medium-to-coal (M:C) ratio is the most important operational parameter of the Dense Medium Cyclones (DMC) that are widely used in the coal industry to upgrade the run-of-mine coal by separating gangue from product coal. However, its effect is still not well understood so far, since the flow [.]

Dense medium cyclones are used extensively in the minerals processing industry around the world and cyclones with larger diameters have been introduced in recent years. Although cyclones have been in use for well over 60 years, the influence of the different process variables such as cyclone dimensions, feed pressure, medium properties and feed rates are not yet fully understood.
