Reference,A water filtration system with magnetite has a more aggressive backwash in the cleaning phase, as well as the ability to recover the magnetite by using a magnet.
Magnetite Oresome Resources. Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore.

The Chance washer utilized sand and water as a medium. Today, the “heavymedia” process using magnetite is standard for coarse coal cleaning.
The most common process for upgrading coarse coal (>12.5 mm) is the heavy media bath. A common type of heavy media bath is the Daniels vessel (Fig. 10).This unit consists of a large open vessel through which an aqueous suspension of finely pulverized magnetite (SG=5.2) is circulated.Promoting the reduction reactivity of magnetite by ,Magnetite supplied by an oredressing plant in China was used as the raw material in this study. The chemical compositions of the impurities within the magnetite were obtained using Xray fluorescence (XRF), as shown in Table 1, and Xray diffraction (XRD) showed that Fe 3 O 4 was the major component.

The amount of magnetite retained would be much greater than it would be in its use as a secondary separator but it has been shown that HGMS separators can retain 80% or more of the solids in a 40% density stream of iron ore without plugging.

Magnetite is produced as a byproduct of the phosphate mining process of Foskor. At our processing plant in Phalaborwa Idwala Magnetite upgrades this material by magnetic separation and fine milling for supply to the Washery Bharat Coking Coal Limited,Introduction: Coal Washing is a process of enrichment of combustibles in coal by removal of noncombustible impurities utilizing industrial separators mainly based on difference in Specific Gravity of Coal and associated impurities like Shale, Sand & Stones etc. so that we get marketable coal suitable for the target consumers. The Washed Determination of Magnetite in DenseMedium Coal ,Abstract. Magnetite losses are generally significant in commercial coal cleaning plants using highdensity medium techniques. It is common practice to monitor the cleaned coal, slurries, and refuse using a Davis Tube method in order to isolate and correct unnecessary losses.
The report describes a demonstration of the successful recovery of magnetite from mixtures of magnetite and coal, like those found in a coalwashing circuit, by High Gradient Magnetic Separation.

Coal Preparation and Cleaning T.D. WHEELOCK and R. MARKUSZEWSKI 1. INTRODUCTION Most coal requires some preparation before use. Preparation may range from simply crushing to provide a size consist suitable for certain types of boilers to extensive size reduction and cleaning to remove sulfur and ash Welcome to Eprints@NML eprints@NML,Welcome to Eprints@NML eprints@NMLHigh Magnetite Consumption CR4 Discussion Thread,Leaks & Spillages. Magnetite losses are usually expressed in kilograms of magnetite per tonne raw coal processed (kg/t ROM), although it is becoming more common to express losses in terms of kilograms of magnetite per dry coarse coal feed (kg/t dccf). Modern coal plants typically have consumption in the order of 0.5kg/t ROM."
