Abstract

A pumpable slurry of mineral particles, e.g., coal, in water contains 50 to 85% by weight of mineral particles based on the combined weight of mineral particles and water. The mineral component contains at least 30% by weight of coarse particles having a particle size in the range 5 to 50 mm, 10 to 40% by weight of fine particles having a particle size less than 200 micron and the balance to 100% of intermediate sized particles. The slurry is stable without the use of additives and can be pumped through a pipeline.
