Pasminco Century Mine's slurry pipeline was commissioned in November 1999. It currently transports zinc and lead concentrate slurries in batch form to the Port facility, 304 km away in the Gulf of Carpentaria. The Pipeline and the Port have gone through several stages of continuous improvement to match the successful ramp-up of the concentrator. Improvements in the Pipeline and Port Operations have included: commissioning of the first slurry pipeline that delivers two products in the same pipeline in batch mode; management of batches throughout the pipeline and port system to minimise cross contamination of both concentrates; operation of the slurry pipeline to achieve high availability of the system; operation of the pump station interfaced with preventive maintenance to minimise unplanned shutdowns; continuous monitoring of pressures throughout the single-station, 304 km slurry pipeline; redesign of the Rotary screw feeder; redesign of the Dryer Control System; installation of a larger Induced Draft Fan; optimisation of the dryer internals to achieve a product of narrow size distribution and pellet integrity; redesign of the stockpile ventilation system; and the development of a surface sealant. This paper describes the early commissioning of both the Port and the Pipeline and the continuous learning and Quality Improvement Project initiated at the Port to focus on concentrate quality given the propensity of the fine concentrate to self-heat during storage.
