Slurry pipeline
The concentrate of the ore is mixed with water and then pumped over a long distance to a port where it can be shipped for further processing. At the end of the pipeline, the material is separated from the slurry in a filter press to remove the water. This water is usually subjected to a waste treatment process before disposal or return to the mine. Slurry pipelines offer an economic advantage over railroad transport and much less noise disturbance to the environment, particularly when mines are in extremely remote areas.
