In ore-dressing the crude ore is crushed and ground to the point where each mineral grain becomes essentially free. By means of various physical methods the mineral grains are separated in various fractions, some of which contain the valuable elements, whereas others are discarded as worthless. The principles of ore dressing have found application also at later stages in metal production.
