Cavex® Hydrocyclones | Weir Group

Hydrocyclones are integral products to process minerals effectively. Their cylindrical top and conical base create a vortex which creates a centrifugal force to separate and classify different sized particles. This vortex forces lighter particles through the top overflow, while denser or larger solid particles pass through the bottom underflow.

cyclone overflow. From there, the fine gold particles that have reported to the cyclone overflow, are extracted through a cyanide leaching and carbon adsorption process. A high-grade gold solution is then produced for electrowinning which is followed by smelting to create doré bars. Doré is a semi-pure alloy of gold and silver.

Hydrocyclone Working Principle

In gold grinding circuits much of the free gold can lie in the finer size fractions and is amenable to concentration using enhanced gravity. Treating only a fraction of cyclone underflow means that much of the free gold will bypass the gravity concentration circuit and report straight to cyclone overflow.

cyclone overflow stream in a typical gold circuit will have a size distribution of 80% passing 75um but in fact the typical gold size distribution will be far lower at around 40um and the grade will be only that of head grade, or lower if a gravity circuit is operating ahead of the

Overflow to Underflow Flowrate Ratio Effect on Dense ...

In the dense medium cyclone separation of coal, the overflow to underflow (O/U) flowrate ratio has not been considered as a major parameter in correlation with the cyclone performance, since it is not directly adjustable. It is a common practice in the optimization of cyclone performance, however, to stipulate the range of cyclone orifice diameter ratios in respect to the cyclone diameter and ...

Better separation: CycloStack CycloWash | FL

The CycloWash, located in the lower/apex section of the hydrocyclone, injects water into the cyclone, and the injection water displaces the fines-laden water in the partially thickened underflow pulp. The result, essentially, is a second stage of classification taking place, where the displaced water with fines joins the normal cyclone overflow.

gold plant cyclone operations - Macelleria Palermo

Cyclone underflow contains the greatest opportunity for gravity concentration since it is the highest grade. (Please refer to flowsheets included.) Recovery across the enhanced gravity device will be improved by the absence of slime. Free gold that escapes from grinding circuits via cyclone overflow will all be recovered by

How to Improve Cyclone Separation

Cyclone control is best obtained by optimising the feed density. With consistent ore types the cyclone feed density is a good indicator of cyclone overflow sizing. A ropy cyclone underflow indicates a very high-density state with a risk of plugging the 'apex'. If control cannot be exercised either a larger apex is needed, or the addition of ...
