Ore Treatment an overview ScienceDirect Topics

Ore Treatment. Mineral processing comprises two principal steps: size reduction to liberate the grains of valuable mineral (or paymineral) from gangue minerals, and physical separation of the particles of valuable minerals from the gangue, to produce an enriched portion, or concentrate, containing most of the valuable minerals, and a discard, or tailing (tailings or tails), containing
