Lead Geoscience Australia

Lead was the first metal mined in Australia at Glen Osmond in South Australia in 1841, after the wheel of a cart being pulled up a rough track accidentally exposed some lead-zinc ore. In 1876, lead-silver ore was discovered and mined at Thackaringa, near Broken Hill in New South Wales, but the mines closed in 1877.

Copper, lead, and zinc are frequently found in massive sulfide deposits. Many such deposits are believed to have been formed by precipitation from volcanic exhalations on the seafloor or by metasomatic replacement (a process of simultaneous solution and deposition).

The ore has first to be separated from clays and other silicates ('gangue') after which the lead ore and the zinc ore are separated. The process used is froth flotation, a succession of stages each delivering a greater concentration of the lead ore. The ore, containing gangue (which typically contains 3-8% lead) is ground with water to a particle size similar to that of fine sand (0.25 mm).
