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 transportation when mines are located in remote, inaccessible areas.

| - Un minéroduc est un pipeline destiné à faire transiter un minéral sous forme d'une suspension liquide (slurry) jusqu'à un port d'exportation ou une zone de traitement. À ce jour[Quand ?], plusieurs projets existent pour faire transiter des minéraux par minéroducs mais rares sont les produits, dont le charbon (carboduc), le fer et le phosphate, qui se prêtent facilement à ce type de transport. Le premier minéroduc au monde à voir le jour serait un pipeline réalisé en Australie en 1967 afin de transporter du fer en émulsion sur une distance de 85 km. (fr)

| - Un minéroduc est un pipeline destiné à faire transiter un minéral sous forme d'une suspension liquide (slurry) jusqu'à un port d'exportation ou une zone de traitement. À ce jour[Quand ?], plusieurs projets existent pour faire transiter des minéraux par minéroducs mais rares sont les produits, dont le charbon (carboduc), le fer et le phosphate, qui se prêtent facilement à ce type de transport. Le premier minéroduc au monde à voir le jour serait un pipeline réalisé en Australie en 1967 afin de transporter du fer en émulsion sur une distance de 85 km. En 2014, au Maroc, l'Office chérifien des phosphates (OCP) a inauguré un réseau de minéroducs de 235 km pour transporter le phosphate de son site d'extraction à Khouribga (à 120 km au sud-est de Casablanca), jusqu'au port de Jorf Lasfar, situé au sud de Casablanca. Ce sont 38 millions de tonnes de minerai qui sont acheminées annuellement. (fr)

Slurry pipelines are used as an alternative to railroad transportation when mines are located in remote, inaccessible areas. Canadian researchers at the University of Alberta are investigating the use of slurry pipelines to move agricultural and forestry wastes from dispersed sources to centralized biofuel plants. Over distances of 100 kilometres pipeline transport of biomass can be viable provided it is used in processes that can accept very wet feedstocks such as hydrothermal liquefaction or ethanol fermentation. Compared to an equivalently sized oil pipeline, a biomass slurry pipeline would carry around 8% of the energy. (en)
