VII. SUMMARY 

Paste technology is proved to be beneficial for disposal 
of tailings. 

As the plasma concentration increases, viscosity and 
yield stress both increases. 

Viscosity decreases while yield stress increases with 
increase in shear rate especially at high plasma 
concentration. 

For less particle size yield stress and viscosity both 
increases. At high concentration curve becomes steeper. 

Rheological properties increase with solid concentration, 
no response shown ratio of tailing/cement but slump is 
affected by the ratio. 

Large initial shear stress and strong internal structure is 
observed for Bingham type rheological model. 
VIII. CONCLUSIONS 
It can be concluded that it is beneficial to have high 
concentration with small particle size with low moisture 
content because it will have high yield stress and viscosity. 
Also, appropriate shear stress to cohesion ratio is decided to 
avoid clogging of pipeline.
