Galena, LEAD ORE - Gunloads.com

May 28, 2010· Galena is lead sulfide, PbS. Heating galena in open air (exposed to oxygen) causes the lead sulfide to react with oxygen and create pure lead and sulfur dioxide: PbS+O2 ---> Pb+SO2 Very simple chemical reaction. Reducing or smelting a small amount of galena would be very easy-- a candle, a pipette, and a block of charcoal is all it would take ...

The most important lead ore is galena (PbS) followed by anglesite (PbSO4) and cerussite (PbCO3). The latter two minerals are formed from the weathering of galena. Five lead mines in Missouri plus lead-producing mines in Alaska, Idaho, Montana, and Washington produce most of the primary lead. In 2003, Alaska and Missouri (“lead-belt” in southeastern part of the state) accounted for 96% of ...

What is the percentage by weigh of lead in Galena? | Yahoo ...

Dec 04, 2009· Galena is the most common ore of lead; chemically it's lead sulfide, PbS. The atomic weight of lead is 207.2 and that of sulfur is 32, so the molecular weight of PbS is 207.2 + 32 or 239.2. The percent by weight of lead is 207.2 / 239.2 = 86.62 % by weight Pb So the closest answer is D; galena is nearly 87% lead by weight.
