Effect of Fine on Paste Thickener Performance Thickening

This case is the first experience of employing paste thickener in copper industries. If there was a hydrocyclone after thickener, addition of coarse particles is possible. if not, we have to looking for another way. To my mind searching for the methods to decrease shear yield stress or producing flocs with lower strength may be a solution.

However, centrifugal pumps can pump paste depending on the rheological properties of tailings (principally the yield stress). High operating costs associated with the thickening and transportation of paste compared to other methods (even filtration). High risk of not achieving paste from the installed paste thickeners.

Rheological Techniques for Yield Stress Analysis

for yield stress analysis of medium viscosity materials. The SR method was found to be useful for very low viscosity materials as yield stresses can be measured accurately as low as 4x10 4 Pa. The DS method was found to be useful over a wide viscosity range and was especially practical for testing high viscosity semi solid materials such as grease.

Bingham plastic

A Bingham plastic is a viscoplastic material that behaves as a rigid body at low stresses but flows as a viscous fluid at high stress. It is named after Eugene C.
