mineral processing - mineral processing - Dewatering: Concentrates and tailings produced by the methods outlined above must be dewatered in order to convert the pulps to a transportable state. In addition, the water can be recycled into the existing water circuits of the processing plant, greatly reducing the demand for expensive fresh water.

Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the ...

Again the addition of polymer aids in the separation and thickening process. The disc filter uses vacuum to dewater the magnetite iron ore concentrate and discharges a relatively dry cake which is sent for pelletizing. This process allows ore of very low magnetite content to be processed into a high quality product. Tailings

Extracted minerals are fed to the thickener as a slurry via a trough. The solids are settled out into the bottom of the tank, in a process accelerated through the addition of flocculants. Precise density measurement of the slurry underflow is necessary for effective control of the ore thickener.

The present invention is related to a high aspect ratio column thickener and a process thereof useful for dewatering of iron ore tailings. The column thickener has been developed with multiple feed inlet points and an auxiliary inlet point for water to clear the jam of high concentration slurry, if required. The column also consists of a conical portion at the bottom.

The particles pass over the screen while the water passes through the apertures in the screen. This process is only viable for coarse ores that have a close size distribution as the apertures can allow small particles to pass through. Sedimentation operates by passing water into a large thickener or clarifier.

Filtration and thickening are areas of mineral recovery technology that are often overlooked. Nonetheless, they represent an important component of the entire process, since without dewatering, it would be hard to produce concentrates to transport specifications while water recycling from tailings streams is becoming increasingly important as energy costs for pumping steadily increase.

Running a thickener properly isn't as easy as it looks. True enough, a thickener doesn't make a racket like a ball mill, or spew out froth like a flotation machine, or bounce up and down like a jig, but down inside that big tank there is a lot going on just the same.

How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids.
