Hydrocyclone
The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds …

The effect of screen versus cyclone classification on the mineral
The hydrodynamic classification of cyclones is strongly influenced by particle density. This density bias is highly significant for mineral processing with generally higher density of mineralized particles relative to gangue. In comparison, separation using screens is based on shape and size only.

Metallurgical Plant Sampling Techniques

Improved Mining Operations by Detecting Roping and …
One of the most ubiquitous operations in any mine is the use of hydrocyclones (cyclones) in the comminution circuit to sort particle sizes for mineral processing. Downstream of this process is the flotation circuit, which can be adversely affected if there is an upset with cyclones. Poor cyclone performance will impact …

Technologies in Exploration, Mining, and Processing
In some cases a cyclone is used to provide centrifugal force to assist in the mineral separation. The mineral used as media is recycled magnetically. This method is widely used for coal and to remove shale from construction aggregates. Early work has been done to develop a low-cost, effective, safe, and environmentally acceptable "true ...

Roping HydroCyclone -Bad Operation
HydroCyclone Roping – Incorrect Cyclone Operation is often caused by too high a volume feeding into the cyclone. If the apex capacity is exceeded a condition known as roping may occur. Normally, the underflow sprays out of the apex. When roping occurs, the air core inside the apex collapses and the spiraling motion is almost lost.

How to Improve Cyclone Separation
Good cyclone separation depends upon control of pressure drop, pulp density and apex size. The 'pressure drop' may vary but should not change rapidly, and is held at safe levels by keeping an adequate sump level. A falling sump level causes cavitation in the pump and reduction in feed rate; pressure drop in the cyclone falls and …
