【 摘 要 】

Present study was focused on the flow characteristics of zinc ore water suspension. The solid concentration was varied in the range of 30-60% (by weight). The rheometer is used to study the flow behaviour of slurry suspension. The slurry exhibits Non-Newtonian behaviour at solid concentration of 30%. Whereas at higher solid concentrations slurry shows Bingham flow characteristics. The increase in temperature shows significant effect reduction of apparent viscosity. Fanning equation was used to predict the pressure drop in horizontal pipe. From the results it was noticed the pressure drop was increased with solid concentration and flow velocity.
