Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined. Most lead is obtained by roasting galena in hot air, although nearly one third of the lead used in the United States is obtained through recycling efforts. abundance Relative proportion (ppm) Abundance in crust (ppm) 1: 8: oxygen: O: 460,000: 474,000: 461,000: 2: 14: silicon [1] Si: 277,200: 277,100: 282,000: 3: 13: aluminium: Al: 81,300: 82,000: 82,300: 4: 26: iron: Fe: 50,000: 41,000: 56,300: 5: 20: calcium: Ca: 36,300: 41,000: 41,500: 6: 11: sodium: Na: 28,300: 23,000: 23,600: 7: 19: potassium: K: 25,900: 21,000: 20,900: 8: 12: magnesium: Mg: 20,900: 23,000: … Reference (Click the next to a value above to see complete citation information for that entry).

It is not considered rare, however, since it is fairly Lead occurs naturally as a mixture of four stable isotopes: 204Pb (1.48%), 206Pb (23.6%), 207Pb (22.6%), and 208Pb (52.3%). Lead is obtained mainly from galena (PbS) by a roasting process. Anglesite, cerussite, and minim are other common lead minerals. Lead has been used by human civilizations for all of recorded history.

“People with a scarcity mentality tend to see everything in terms of win-lose. There is only so much; and if someone else has it, that means there will be less for me. Abundance is measured in one of three ways: by the mass-fraction ; by the mole-fraction ; or by the volume-fraction. Volume-fraction is a common abundance measure in mixed gases such as planetary atmospheres, and is similar in value to molecular mole-fraction for gas mixtures at relatively low densities and pressures, and ideal gas mixtures. And the kings of the earth have committed fornication with her. (On the figure employed, as well as the identical language, see Revelation 17:2.)
