Pipelines must be suitably engineered to resist abrasion from the solids as well as corrosion from the soil. Some of these pipelines are lined with high-density polyethylene (HDPE).
Slurry pipelines are also used to transport tailings from a mineral processing plant after that the ore has been processed to dispose of the remaining rocks or clays.
For oil sand plants, a mixture of oil sand and water may be pumped over a long distance to release the bitumen by attrition. These pipelines are also called Hydrotransport Pipelines.
One of the longest slurry pipelines was to be the proposed ETSI pipeline, to transport coal over a distance of 1036 miles (1675 km). It was never commissioned. It is anticipated that in the next few years some long distance slurry pipelines will be constructed in Australia and South America where mineral deposits are often a few hundred kilometers away from shipping ports.
Slurry pipelines are also considered to de-silt or remove silts from deposits behind dams in man-made lakes. After the Hurricane Katrina disaster there have been proposals to pump silt to the shore and remedy the environment. Proposals have also been made to de-silt Lake Nubia-Nasser in Egypt and Sudan by slurry pipelines as Egypt is now deprived of 95% of its alluvium that used to come every year. These projects to remedy the environment will be very beneficial to the damage caused by large dams and man-made lakes.
