Galena (Illinois) – Travel guide at Wikivoyage
Galena is a city in the Illinois Driftless Area 16 miles east of Dubuque, Iowa and 163 miles west from Chicago is known as "The City that Time Forgot" for its rich 19th century heritage. Named after the local lead deposits, the city was founded in 1826 and was a major port on the Mississippi River.
Word Equation: Lead (II) Oxide + Carbon à Lead + Carbon Dioxide. Chemical Equation: 2PbO + C à 2Pb + CO 2. There is another process in which the galena mineral can be smelted through . It also requires two chemical reactions to occur within the furnace. 1) Due to the sulfur content, carbon from the coke will not be able to reduce lead.

Lead Zinc Separation by Flotation
The relative galena and sphalerite contents do not change the surface chemistry and tend only to have an impact in cases where the galena content is higher than the sphalerite content, e.g. at Cannington where if the lead feed grade relative to zinc is too high, then too much of the faster floating zinc with lower iron content is recovered to ...
