About this site

Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.

Zinc and Lead

Zinc (Zn) is a bluish-white lustrous metal that is brittle at room temperature, but malleable when heated. It has a low melting point (419.5°C) and a moderately high specific gravity (7.13). Lead (Pb) is a soft, ductile, malleable, bluish-white metal with a low melting point (327.4°C) and a high specific gravity (11.3). Zinc and lead minerals often occur together because, as elements, they ...
