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 leadzinc ore. In 1876, leadsilver ore was discovered and mined at Thackaringa, near Broken Hill in .
As nouns the difference between lead and leed is that lead is (uncountable) a heavy, pliable, inelastic metal element, having a bright, bluish color, but easily tarnished; both malleable and ductile, though with little tenacity it is easily fusible, forms alloys with other metals, and is an ingredient of solder and type metal atomic number 82, symbol pb (from latin plumbum ) or lead can be ...
Lead ochre PbO. Extraction: Lead is mainly extracted from the sulphide ore galena. Galena contains lead sulphide and small quantities of silver. 1. Concentration: The ore is concentrated by froth floatation process. 2. Smelting in a Reverberatory furnace: The concentrated ore is roasted in a reverberatory furnace at a moderate temperature.
