Quarry Fines and Waste COnnecting REpositories
Quarry fines are generated by processes related to blasting, processing, handling and transportation. Particle shape, as well as grading and fines content, are a function not only of the crushing process but also of the mineral composition and texture of the rock. As a rule of thumb, a coarse-grained rock will generate fewer fines than a fine-grained rock. This is because it takes less energy
