A method of transportation of mineral ores by pipeline. The method comprises the steps of crushing the ore into relatively fine particles, mixing (3) the crushed ore with a liquid carrier to form a relatively high density mineral slurry, injecting a gas to aerate the slurry and produce a relatively low density mineralised froth, and pumping (5) the aerated slurry and froth along a fluid pipeline (6). A corresponding apparatus is also provided.
L'invention concerne un procédé d'acheminement de minerais par pipeline. Le procédé consiste à concasser le minerai en particules relativement fines, à mélanger (3) le minerai concassé avec une charge liquide pour former un coulis minéral de densité relativement élevée, à injecter un gaz pour aérer le coulis et produire une mousse minéralisée de densité relativement faible, et à pomper (5) le coulis et la mousse aérés dans un pipeline à fluide (6). L'invention concerne aussi un système de mise en oeuvre du procédé.
