A process for the wet concentration and cleaning of fine coal is provided which comprises the steps of desliming and thickening a dilute slurry of fine coal and contaminant particles having a size of less than about 10 mm by introducing the same to a hydrocyclone separator to retain a slurry of particles having a size greater than about 0.1 mm, wet concentrating the last named slurry and.
This grade of magnetite is required for washing coal re duced to 100 mesh and is the grade expected to be used at Homer City. Only one brand of magnetite was used on the advice of Bureau of Mines personnel. The magnetite is mined, crushed, and ball mill ground until the 325 mesh re quirement is met. It is dried by the supplier.
Magnetite is the most widely used material for heavy media because of its higher stability in suspension, higher specific gravity, lower viscosity and easy avai lability.Worldwide, almost 60 of total coal beneficiation is carried out by heavy media process. In India in 80 cases the heavy media used is magnetite.
The dense medium cyclone (DMC) process used in coal beneficiation plants is studied from a control system perspective. Employing the dynamic model of the DMC process derived from mass flow balance.
What is magnetite for in a coal washing plant. The dense medium separation process used in most coal washing and magnetic separation plants requires a suspension of finely milled magnetite in water Magnetite for coal washing must be of overall high purity and be devoid of contaminants such as hematite sulphides or other minerals.
In coal preparation, the mineral magnetite (FeO, Fe 2 O 3) has become the most commonly used material, not only because it fulfils all the above criteria, but also because of its worldwide occurrence either as an iron ore or as a by product of mining operations for other minerals. Like any mineral, magnetite rarely occurs in the pure state and.
