Lead and Zinc - Energy.gov

6.1.2.2 Lead and Zinc Ore Concentration If the mineral veins separate from the rock cleanly, then processing workers can concentrate the ore by taking advantage of the greater weight mineral compared to the rock. Jigging separates coarse lumps. In this process, the crushed ore is agitated or shaken in water with a vertical motion.

When ore is processed (typically very close to the mine), it is ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a concentrate. At a molybdenum mine, for example, this concentrate may be almost pure molybdenite (MoS 2). The rest of the rock is known as tailings. It comes out of the ...
