Indian iron and steel producers are aiming for transporting the run-of-mine (ROM) iron ore through slurry pipelines at a competitive price. Thus, it is quite imperative to study the flow characteristics of concentrated iron ore fines slurry for predicting the pumping pressure as well as designing such commercial slurry pipelines.Slurry pipeline - Wikipedia,A slurry pipeline is a specially engineered pipeline used to move ores, such as coal or iron, or mining waste, called tailings, over long distances. A mixture of the ore concentrate and water, called slurry, is pumped to its destination and the water is filtered out. Due to the abrasive properties of slurry, the pipelines can be lined with high-density polyethylene (HDPE), or manufactured completely from HDPE Pipe, although this requires a very thick pipe wall. Slurry pipelines are used as an alternative to railroad tran…WO2012047336A2 - Mineral slurry drying method and system,,The present invention provides a method and system for drying mineral slurry concentrate and high moisture content minerals using activated alumina.
