Lead and Zinc - Energy

2013-11-8  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.

Zinc: smelting, producing and classification-Metalpedia

Zinc ores contain 5-15% zinc. To concentrate the ore, it is first crushed and then ground to enable optimal separation from the other minerals. Typically, a zinc concentrate contains about 55% of zinc with some copper, lead and iron. Zinc concentration is usually done at the mine site to keep transport costs to smelters as low as possible. Zinc ...
