Lead is naturally occurring in rocks that make up the Earth's crust, mostly in the form of the minerals galena (lead sulfide), anglesite (lead sulfate) and cerussite (lead carbonate), and can be spewed into the atmosphere by erupting volcanoes, eventually settling onto agricultural soils and reservoirs.
Mar 09, 2015· Galena, Kansas is a former mining town, named in 1877 for galena, a lead sulphide ore extracted locally. U.S. Route 66 was designated in 1927; by 1929 Kansas and Illinois were the first to completely pave their respective segments of this highway.

The lead telluride mineral altaite has the same crystal structure as galena. Within the weathering or oxidation zone galena alters to anglesite (lead sulfate) or cerussite (lead carbonate). Galena exposed to acid mine drainage can be oxidized to anglesite by naturally occurring bacteria and archaea, in a process similar to bioleaching.
At the end of the Ryder Cup five captains are chosen to lead their team of four into a Best Ball Scramble. Some of the best stories come from these 4 hours which include - 1) Smitty's Cutout T-Shirt. 2) Fagan's Attempt at Teeing off with Zajeski's Glasses. 3) Paul's Muff. 4) Football after the 18th Hole
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.

deposits virtually guarantee that our state will be a leading producer of lead for years to come. Since 1720 galena has played an important role in the history and economics of Missouri. Thus, it was most fitting that in 1967 the 74th Missouri General Assembly designated GALENA the official mineral of the State of Missouri.
As part of the U.S. Bureau of Mines program to improve base metal leach systems, pressure leaching of galena (PbS) concentrates in fluosilicic acid (H2SiF6) solution was investigated. Lead extraction was 93 pct when PbS was pressure leached in H2SiF6 at 95° C with 200-psig O2 pressure for 40 min, using ferric nitrate [Fe(NO3)3] as a catalyst.
Upon completion of the merger, Galena's board of directors will resign, and a new board of directors will be constituted consisting of seven members that will include five representatives appointed by SELLAS, two of whom will be independent directors, and two representatives designated by Galena subject to SELLAS' approval.
