Lead Antimony Alloy | AMERICAN ELEMENTS

Antimony (atomic symbol: Sb, atomic number: 51) is a Block P, Group 15, Period 5 element with an atomic radius of 121.760. ... Lead is obtained mainly from galena (PbS) by a roasting process. Anglesite, cerussite, and minim are other common lead containing minerals. Lead does occur as a free element in nature, but it is rare.

Extraction of Antimony - Element Antimony, Sb, Metalloid

For roasting sulphide ores two methods are used, viz., simple roasting yielding mainly antimony tetroxide, and volatilisation roasting yielding mainly antimony trioxide. In the former, reverberatory furnaces are employed, the flue gases passing through a condensing plant for the recovery of any antimony trioxide that may be formed.

The Behavior of Stibnite in an Oxidizing Roast

In the roasting process the aim may be to leave the oxidized antimony in the ore, or it may be to volatilize as much of the antimony as possible, collect the volatilized oxide as a rich intermediary product and smelt it for antimony, leaving the gangue poor enough to be considered a waste product.

Oxidizing roasting is the classical method used for the pretreatment of dirty copper concentrates to remove the unwanted impurities through the gas phase, a process where arsenic is removed effectively but antimony and bismuth removal is poor at the roasting temperatures (500–700 ℃) due to the formation of nonvolatile oxides [2, 3, 4].
