Effect of Slime and Impurity Removal as a Pre-Treatment ...
Abstract A low-grade zinc-oxide sample (6–8% Zn) from Mehdiabad mine in Iran, with a high amount of slime and iron (17–19% Fe) and manganese (5–7% Mn) impurities was studied. Pre-treatment processes, such as desliming and wet high-intensity magnetic separation were applied for impurity removal. Petrographic studies showed that the zinc minerals were …

Hydrocyclone Feed Pump & Pressure PSI vs Operating Parameters
For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure fluctuation.. First the pump …

Hydrocyclones - an overview | ScienceDirect Topics
Hydrocyclones are cono-cylindrical in shape, with a tangential feed inlet into the cylindrical section and an outlet at each axis. The outlet at the cylindrical section is called the vortex finder and extends into the cyclone to reduce short-circuit flow directly from the inlet. At the conical end is the second outlet, the spigot.
