Processing metallic ore (e.g., gold, silver, iron, copper, zinc, nickel, and lead) can involve numerous steps including crushing, grinding with water, physically separating the ore minerals from non-ore minerals often by density, and chemically separating the metal from the ore minerals using methods such as smelting (heating the ore minerals ...

Modern Uses of Lead. Prior to the early 1900s, lead was used in the United States primarily in ammunition, burial vault liners, ceramic glazes, leaded glass and crystal, paints or other protective coatings, pewter, and water lines and pipes. Following World War I, the demand for lead increased because of growth in the production of motorized ...

In the case of the zinc and lead-zinc mines analyzed, the average zinc ore grade is 9.6% and the average lead ore grade is 3.4%. These mines produced more than 1 million tonnes in 2009, which corresponded to approximately 16% of the total zinc world production that same year [ 42 ].
