Development of slurry transportation technology in Sweden

• A system-oriented development project has been started by the LKAB mining company and Chalmers University of Technology (CTH), in co-operation with manufacturers and inventors. The development work has concentrated on improvements of some components and better understanding of specific problems, which, seen together, are believed to be of great interest in slurry transportation applications. So far, a rubber-lined plastic pipe for high-pressure applications has been developed, and a high-pressure pump without large external devices and with a minimum of moving parts is to be patented. Simultaneous laboratory and in-plant tests of the new components have been started, and studies on freezing problems, chemical additives, and secondary flow have also been carried out. A pilot-plant investigation on hydraulic hoisting of heavy ore by centrifugal pumps has been completed at CTH.
