2013-11-8  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.

2001-6-1  Pyrometallurgical slag, produced 100–150 years ago from lead–zinc ores in the smelting region of Příbram, Czech Republic, contains elevated amounts of Zn and Pb. Knowledge of the distribution of these elements in the main phases and an investigation of natural weathering features represent the first step in the environmental assessment related to dumping of metallurgical slag.
